    Description: As a program supporting academic research that addresses recognized societal needs, theFlorida Sea Grant Program is developing a research theme area on estuaries to provide a uniquely academic product that will augment mission-oriented research undertaken by government and bythe private sector. This report is not a call for proposals. It does not prescribe a specific researchplan. Rather, it is a concept paper designed to focus research on two broad "organizing themes":(1) the hydrology of Florida's estuaries, and (2) the impact of cyclic environmental variability onestuarine function.

    Description: A brief analysis of the bsics of artificial reefs as well as the methods and techniques in use are provided. The need for clear objectives and the design of artificial reefs for long-term goals is emphasized. Several principles are established. First, artificial reefs must target the enhancement of biological and fishery production of the Cuban shelf. This principle introduces major changes in current concepts, which are bsed exclusively on the increase of catch per unit effort. Second, an adequate balance between fishing effort, refuge capacity, food availability and fish recruitment must be established. Therefore, the use of artificial reefs siwth many cavities as habitats for algae, invertebreates and fishes, in place of artificial reefs exclusively employed as fish aggregators, is discussed. A methodology for a national development program, including the materials, structures, reef configurations, quantities, and distributions is proposed. As a result of examinations of habitats on the four sections of the Cubman shelf, an area of 12,500 sq.km. is defined as adequate for artificial reefs and isolated refuges. Eight-hundred and fifty reefs, each one formed by 200 refuges, are proposed. The use of artificial reefs for recreational fisheries is recommended for Cuba.(English & Spanish editions, 46 pgs in each edition; full text searching unavailable)

    Description: The shoaling and bank erosion at Ponce de Leon channel, Punta Gorda, Florida, havecaused concern of harming the mangrove community along the channel. Three factorswere identified that could contribute to the bank erosion of Ponce channel. Theyare tidal induced current, wind waves penetrating from the Charlotte Harbor, andwakes caused by boat traffic. According to the field experiments and numericalmodeling studies, it was determined that the combined wind wave and tidal currentforce is the major cause to the bank erosion. Wind wave appears to play a moreimportant role because of its dynamic nature. For the present cross-sectionalchannel condition the tidal current alone is only a moderate erosional force.It was also found that reopening the barge canal would cut the tidal currentstrength in the Ponce channel by a half. This current reduction would reduce butnot eliminate bank erosion in the lower reach as the wind-wave induced force willremain to be an important erosional factor.A number of remedial alternatives were given in the report. The most direct methodis to provide bank protection. The extent of the protection depends upon theextent of wind wave penetration which could be as deep as 150 m into the channelunder the present channel entrance condition.

    Description: This is the first of a pair of reports documenting the effects of storms on barrier island systems.The present report (Volume 1) investigates storm effects on natural island conditions whereasVolume 2 addresses the effects of seawalls. With the aim of simulating the effects of overwashon barrier islands and characterizing their response, a series of nine experiments was conductedat the Coastal Engineering Laboratory of the University of Florida. The barrier island wassimulated by a 400 feet wide (prototype units) horizontal crest and an initially planar (1:19)beach. The effects of various storm surge levels and accompanying overtopping were investigated.Experiments were conducted with both regular and irregular storm waves. Regularwaves without overtopping caused the formation of a substantial berm in the swash zone and aprominent longshore bar offshore. Increasing degrees of overtopping resulted in substantial lossof sand from the barrier island system. The longshore bar was considerably more subtle for thehighest water level tested (11.5 ft. above mean sea level). Simulation of a storm-surge hydrographwith rising and falling water levels indicated that the presence of the bar tends to occuronly during a relatively steady or slowly changing water level. The experiments with irregularwaves were conducted with reasonably similar wave heights and carrier periods as those withregular waves. The major difference was in the characteristics of the longshore bar response. Incomparison with cases with regular waves, the bar was less distinct without overtopping, subtlewith minimal overtopping and absent in cases with substantial overtopping. These experimentsseem to indicate that offshore bars are simply break-point bars which require a fairly steadybreak-point and undertow (return of mass transport) for optimal formation.

    Historical shoreline response to inlet modifications and sea level rise (2021)

    Description: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.

    Description: This is the second of a pair of reports documenting the effects of storms on beach systemsincluding the presence of seawalls. With the aim of simulating the effects of overwash onbarrier islands with seawalls and characterizing their response, a series of eight experimentswas conducted at the Coastal Engineering Laboratory of the University of Florida. The barrierisland was simulated by a 400 feet wide horizontal crest and an initially uniform mildly-sloped(1:19) beach. The effects of positioning the seawall at two different locations as well as the effectsof various storm surge levels and accompanying overtopping were investigated. Experimentswere conducted with both regular and irregular storm waves. With the seawall located at theslope break between the crest and the sloping beach of the barrier island, and the crest of theseawall just submerged in sand, the effects on the sediment transport process were found to beminimal. For the same position of the seawall but with the crest of the seawall raised above thesurrounding ground level, overtopping caused washover of sand indicating substantial transportin suspension. Increased levels of overtopping tended to accentuate bed profile changes butsupress bar formation (as did irregular waves). Positioning the seawall at the Mean Sea Levelshoreline caused significant scour both immediately landward as well as immediately seawardof the seawall. A prominent scour trough developed further seaward. The longshore bar washighly three-dimensional. It appears that seawalls need to be located adequately landward of theshoreline to discharge their function effectively without adverse effect to the beach. In addition,concerns for safety warrant the presence of an adequate buffer-zone between the seawall andthe upland property. (61 pp.)

    Description: Red imported fire ants (Solenopsis invicta) invaded peninsular Florida morethan 30 years ago. Highlands and Polk counties, Florida, were probably first invaded inthe late 1960s. Since then, fire ants have continued both to spread and to increase inabundance. Experimental evidence has shown that red imported fire ants may have adetrimental impact on native species, both invertebrate and vertebrate, and that theseimpacts may be both direct and indirect. This segment of research was designed todetermine if fire ants have a negative impact on Florida grasshopper sparrow(Ammodramus savannarumfloridanus) populations at Avon Park Air Force BombingRange, Florida. The sampling reported herein was conducted during June and October,1997, and all analyses are restricted to data collected during those periods. As assessedby baits, fire ants were dominant on about half the sites, and absent from others. Inparticular, OQ Range sites tended to have fewer fire ants present, while Delta Trail siteswere more heavily infested, although there were exceptions. June fire ant abundance wasstrongly negatively correlated with both native ant abundance (r = -0.743, P = 0.006) andnative ant species richness (r = -0.730, P = 0.007). October fire ant abundance wasstrongly negatively correlated with both native ant abundance (r = -0.690, P = 0.013) andnative ant species richness (r = -0.736, P = 0.006). The patterns of fire ant abundance asassessed by pitfalls were very similar to those determined from bait sampling. June fireant abundance was negatively correlated (p 〈 0.05) with native ant richness, but otherJune comparisons were not statistically significant (P 〉 0.05). October fire antabundance was negatively correlated (P 〈 0.05) with native ant richness and abundance,but other comparisons were not statistically significant (P 〉 0.05). There was nosignificant correlation between overall insect biomass as assessed by light traps and fireant abundance as assessed by baits or pitfalls. Total biomass varied considerably amongthe two sample periods because of changes in overall insect abundance during differentseasons. There was a negative spatial correspondence between fire ants and nativeinvertebrates. Over most of the intensive study areas, there was a negative spatialrelationship between fire ants and the abundance of native invertebrates. Over about50% of the intensive study areas, there was a negative spatial relationship between fireants and the abundance of Florida grasshopper sparrows, although the relationship wasnot as strong as that between fire ants and native invertebrates. Fire ant and nativeinvertebrates were negatively correlated at grasshopper sparrow count locations (r =0.347,P = 0.03). A multiple regression model was fit to the data, using fire ants andnative invertebrates as independent variables, and grasshopper sparrow 100-m populationestimates (n = 39) as the dependent variable. The influence of fire ants on grasshoppersparrows was negative while the influence of native invertebrates was positive.However, the overall model, while suggestive, was not significant (r = 0.304, P = 0.17).Fire ant abundance was a better (negative) predictor of sparrow populations (P = 0.13)than was invertebrate abundance (P = 0.59). The overall model and influence of fire antson sparrow populations was suggestive of a negative influence warranting analyses ofdata for 1998 and 1999. (Document has 93 pages)

    Description: The Kemp's ridley (Lepidochelys kempo is considered the most endangered ofthe seven extant marine turtle species (Ross et al. 1989). The US Fish and WildlifeService (USFWS) and the National Marine Fisheries Service (NMFS) estimate thebreeding population at 1,500 to 3,000 individuals. The nesting population has beenreduced from approximately 40,000 on one day to no more than 700 annually(Magnuson et al. 1990, USFWS & NMFS 1992). Conservation measures for thespecies have focused on the protection of the nesting beach, captive rearing (headstarting), and the implementation of turtle excluder devices (TEDs) on shrimp nets. Fivehundred to 5,000 ridleys are still taken incidentally yearly by shrimp trawls (Magnuson etal. 1990). Lack of knowledge about early life stages of the Kemp's ridley sea turtlecurrently hinders recovery efforts for this federally listed species. (Document has 18 pages.)

    Description: The value of the natural resources of the White River Basin (Basin), AR isrecognized by the area's designation as a "Wetland of International Importance". TheBasin constitutes one of the Nation's largest remaining intact forested wetlandlandscapes, second only to the Atchafalya Basin. It supports the North Americancontinent's largest concentration of over-wintering mallard ducks, a world-class troutfishery, the last vestige of a big river fishery remaining in the Mississippi River Basin,and numerous threatened and endangered species. The continued viability of thiswetland ecosystem depends on the suitability of the hydrologic environment to theresident flora and fauna. Numerous modifications of the Basin hydrologic features in thepast century have seriously impaired the sustainability of these resources. The Basinwidealterations of hydrologic processes (e.g., impoundment and regulatory releases offlows and volumes in the upper reaches, navigational modifications of lower reaches, andconsumptive demands for agricultural use throughout) have affected the hydrology of thesystem profoundly. The result is highly regulated flows and stages, vastly alteredhydrologic patterns, over-stabilized water levels, and disruption of seasonal waterdistribution patterns. Given the critical nature of hydrology in regulating the structureand function of wetland ecosystems, the impacts have been devastating, particularly tothe critical bottomland hardwoods that support the Basin's fish and wildlife resources.To date these piece-meal, system-wide, hydrologic alterations have cornmutativelydegraded the habitat value of this resource for fish and wildlife in the Basin, and havelead to changes in their numbers and distributions. In spite of the enormous stakesinvolved, there has been no comprehensive characterization of the Basin hydrology.System alterations such as channel deepening, dam construction, water allocationplans, and flood control measures are currently pending. These projects will potentiallyhrther modify the hydrologic environments of the Basin, and no doubt require mitigationmeasures. In addition, there is genuine interest in restoring aspects of the Basin's historichydrologic regime within some set of reasonable limits. In order to proceed with thiseffort, the anticipated effects of these modifications and restorations on the Basin ecologyrequire thorough study of the area's historic hydrology, so that connectivity among Basinprecipitation patterns, flow fluctuations, and land use changes can be made. A basinhydrologic characterization is an initial component of this effort. The focus of this effortwas to determine and assemble the data set from which characterization of the hydrologicenvironments of the Basin using historic and recent water level, flow, (primarily byUSGS-WRD) at locations throughout the Basin could proceed.

    Description: This report presents the results of a bathymetric surveying program carriedout on the beach and nearshore region about 1 km to the north of the PortCanaveral inlet. The survey data covers a period between March 16 and July 21,1988. The data was collected in support of a field study on directional wavemeasurement and Bragg reflection from artificial, shore-parallel bars, performedduring June-July, 1988. The topography at the experiment site was generallymonotonic in the on-offshore direction (except near the end of the experimentalprogram) and uniform in the longshore direction. (64 pages)

    Description: Loxahatchee can be grouped into three zones according to the patterns of change of treeislands observed from 1950 to 1991. 1 ) the edge ofthe refuge adjacent to the canals, 2) the eastern interiorof the refuge, and 3) the western interior ofthe refuge. The general trend is for tree islandsAlong the edge of the refuge to have decreased insize, number, and percent cover, while those on theinterior increased in size, nunber, and percentcover.Results from this study illustrate the importanceof flow magnitude as well as hydroperiodand depth in stucturing patterns of tree islandswithin this peat wetland. Restoration of historichydroperiods and depths without historic flow patternsmay not be sufficient to restore or maintainthe historic pattern and function of the system. (60 pages)

    Description: We present a new modeling method for use in large-scale physical systems, such as the Everglades ecosystem.The current work that has been done in the ATLSS (Across-Trophic-Level System Simulation) project-whichfocuses on simulating key Everglades system components-relies on code integration. While this represents anecessary first step in analyzing the dynamics of species within the Everglades, it falls short of true modelintegration. We have constructed a methodology called object-oriented physical modeling (OOPM), which allowsa comprehensive knowledge representation to be constructedfor large-scale systems. OOPM enforces theidea that an implementation ofcomputer code can be accomplished in an incremental fashion by starting with aconceptual model and progressing to more detailed models. During this evolutionary procedure, a minimal amountof code is written, since the emphasis is on developing the conceptual model so that it not only represents theintuitive aspects ofthe model, but is also executable. OOPM provides a kind of "blueprint" for ecologists, biologistsand hydrologists to communicate and integrate models effectively. (14 page document)

Transect methods sample a representative portion ofthe total study area, thus allowing for statistical extrapolation to the total area. Otheradvantages of transect methods are less flight time and less cost than total coverage, easeof navigation, and reduced likelihood of double-counting.Our objectives were: (1) to identify visibility biases associated with the transectsurvey method and to adjust the counts accordingly; (2) to derive a population estimatewith known variance for the Banana River during summer; and (3) to evaluate thepotential value of this survey method for monitoring trends in manatee population sizeover time.

    Description: Along EAFB on Cape San BIas, the only sea turtle species nest observed has beenthe loggerhead turtle. The first green turtle nest documented along the Florida panhandlecoast was observed on EAFB property, however (D. Atencio, EAFB, pers. comm). SantaRosa Island, located approximately 150 miles west of Cape San BIas supports a small butconsistent, group of nesting green turtles (Fig. 2). Although erosion is not as severe alongSanta Rosa Island as it is on Cape San BIas, and vehicular traffic is not permitted, seaturtles nesting on this barrier island must survive severe tropical storms, predation, andartificial lighting to be successful. Because this area supports a rare group of nesting greenturtles and is disturbed by intense artificial lighting from Air Force missions and adjacentresort towns, continued monitoring is necessary. The sea turtle species that nest along thisbarrier island, and the human activities that disturb those sea turtles present uniquecircumstances for management ofthis area. Protection ofthe significant nestingpopulations of sea turtles on EAFB properties on Cape San BIas and Santa Rosa Islandrequires yearly monitoring of the nesting activity and the natural and human disturbancesinfluencing the nesting females.The objectives ofthis study were to monitor sea turtle nesting along EAFB onCape San BIas to determine number of nests and hatching success, assess disturbances,and determine proper management to ensure successful nesting and hatching.(56 page document)

    Description: This report responds to the 1986 Beaches Bill which, in recognition of thepotential deleterious impact on Florida's beaches of inlets modified for navigation,mandated a study of those inlets with identification of recommended action to reducethe impacts. This report addresses west Coast inlets; East Coast inlets are thesubject of a companion report.There are 37 inlets along that portion of Florida's West Coast commencing fromPensacola Bay Entrance to Caxambas Pass at the south end of Marco Island. Compared tothose on the East Coast, most West Coast inlets have not had the deleterious effectson the adjacent beaches, yet all modified inlets without proper management have thepotential of impacting unfavorably on the adjacent shorelines. Moreover, at presentthere is interest in opening three West Coast entrances which either have been openin the past (Midnight Pass) or which have opened occasionally (Navarre Pass andEntrance to Phillips Lake).A review of inlets in their natural condition demonstrates the presence of ashallow broad outer bar across which the longshore transport Occurs. These shallowand shifting bar features were unsuitable for navigation which in many cases has ledto the deepening of the channels and fixing with one or two jetty structures. Inlets in this modified state along with inappropriate maintenance practices have thepotential of placing great ero$ional stress along the adjacent beaches. Moreover.channel dredging can reduce wave sheltering of the shoreline by ebb tidal shoals andalter the equilibrium of the affected shoreline segments. The ultimate in poor sandmanagement practice is the placement of good quality beach sand in water depths toogreat for the sand to reenter the longshore system under natural forces; depths of 12ft. or less are considered appropriate for Florida in order to maintain the sand inthe system.With the interference of the nearshore sediment transport processes by inletsmodified for navigation, if the adjacent beaches are to be stabilized there must bean active monitoring program with commitment to placement of dredged material ofbeach quality on shoreline segments of documented need. Several East Coast inletshave such transfer facilities; however. the quantities of sand transferred should beincreased. Although an evolution and improvement in the technical capability tomanage sand resources in the vicinity of inlets is expected, an adequate capabilityexists today and a concerted program should be made to commence a scheduledimplementation of this capability at those entrances causing greatest erosionalstress on the adjacent shorelines.A brief summary review for each of the 37 West Coast inlets is presentedincluding: a scaled aerial photograph, brief historical information, several itemsrelated to sediment losses at each inlet and special characteristics relevant toState responsibilities. For each inlet, where appropriate, the above infor~tion isutilized to develop a recommenced action. (PDF has 101 pages.)

    Description: Current plant canopy wind flow models require three aerodynamic parametersto predict the effects of wind on sand transport--the plant drag coefficient, Cd, the leafarea density profile, LAD, and the turbulent eddy transfer coefficient, 6,. The LADand Cd characterize the plant canopy and its effects on air flow and, prior to thisstudy, data on these parameters for dune vegetation did not exist. The purpose of thisstudy was to design and test a methodology for measuring the wind drag coefficient ofcoastal dune plants. The objectives were 1) to measure and record the parametersneeded to calculate Cd, namely, the force, relative velocity and air temperature; 2) tomeasure the leaf area density of sea-oats; 3) to validate the method by measuring thequantities needed to compute the drag coefficient for a right circular data exists; and 4) to explore the Reynolds number dependence of the canopy dragcoefficient.

Further, the level andbreadth of activity in Florida makes it a bellwether, nationally and worldwide, for interestsconcerned with aquatic science, ecosystem management and environmental technology forhabitat restoration or creation.Recent developments in Florida have prompted increased interest and effort in “monitoring”of reefs. These include extensive studies and disseminating results by the academicresearch community and the advent of governmental funding for monitoring projects in Floridacounties. In response, this study was undertaken to gauge this growing field. Assessment of reefperformance—including evaluation of how well they meet objectives for which they werecreated—has been a neglected subject in many areas of the world. More immediate issues ofreef materials selection, siting and deployment usually take precedence in the short-term.A principal readership for this paper is the network of county-level organizations andindividuals whose largely independent efforts, taken as a composite, make up much of theFlorida reef “program.” Information presented here describes the extent and nature of reefmonitoring in Florida counties, how data are managed and aspects of communication aboutreefs.

    Description: Vacuum-packed Yellowfin tuna steaks were individually frozen in either liquid Freon or in an air storage freezer, and evaluated for keeping quality after 1, 3, and 6 months of frozen storage (-27OC). The resulting freezing rates were used to project the economic feasibility of a small scale commercial processing plant. Regardless of freezing method the vacuum-packed steaks demonstrated keeping quality comparable to fresh control samples handled as in normal distribution channels. The estimated cost to manufacture allowed sufficient profit at competitive selling prices to generate a rate of return of 132%. This would pay back the estimated cost of plant and equipment in less than one 6-month season of operation at full capacity (16pp.)

    Description: The critical need to predict the turbidity in water due to fine-grained sediment suspensionunder wave action over mud deposits for sedimentation and erosion studies, as well assorbed contaminant transport, is well known. Since fall velocities of fine sediment particlesare very small, they can be easily transported by hydrodynamic flows such as waves andcurrents. The presence of these particles in the water column affects accoustic transmission,heat absorption and depth of the eutrophic zone (Luettich et al., 1989). Because these sedimentsalso have a strong affinity for sorbing nutrients and toxic chemicals, sediments whichhave been deposited on the bottom may function as a source of contaminants to the watercolumn if they are disturbed by eroding forces resulting, for instance, from wave action. Anoutstanding example of a water body for these problems is Lake Okeechobee, the largestshallow lake in Florida. This lake shows typical signs of artificial eutrophication mainly dueto increased phosphorus loading associated with the surrounding region. Resuspension of sediment at the bottom of Lake Okeechobee composed of fine-grainedmaterial has been examined. A sediment transport model was used to simulate likelytrends in the evolution of the vertical suspended sediment concentration profile resultingfrom wave action, and the corresponding eroded bed depth was calculated through massbalance. Requisite information on characteristic parameters and relationships related tofine sediment erodibility were derived from field sampling of bottom sediment in the lake,and through laboratory experiments using this sediment and lake water.

The model is very stable and is capableof handling complicated topographies including inlets and irregularly-shapedstructures such as curved jetties and breakwaters.The purpose of three-dimensional models is to predict the change of bottomtopography from the spatial distribution of the sediment transport rates, which areevaluated from the nearshore wave and current fields computed point by point insmall areas defined by a horizontal grid placed over the region of interest. Modelsof 3-D beach topography change require much fewer idealizations than do the linemodels. (Document has 43 pages.)

    Description: The Cabo Rojo Salt Flats, at the southwestern tip ofPuerto Rico, provide important autumn stopover and winteringhabitat for migratory shorebirds. I studied the abundanceand distribution of shorebirds and their food resources atthis site during autumn of 1990 and 1991.Small calidrids (primarily Calidris pusilla and C.mauri) were the most abundant shorebirds at the salt flats.The maximum weekly counts of small calidrids in 1990 (2,690)and 1991 (3,532) occurred in mid October. Calidrids foragedprimarily in the Fraternidad lagoon system; roosting tookplace most often at the neighboring Candelaria Lagoon.The macroinvertebrate prey important to calidrids in theFraternidad system were Dasyhelea (Diptera), Trichocorixa(Hemiptera), and Artemia (Anostraca). Changes in invertebrateabundance coincided with fluctuations in salinity. (100 page document)

    Description: West Indian manatees (Trichechus manatus) occur throughout the year inrivers, estuaries and coastal areas of Florida (Moore 1951, Hartman 1974,Irvine and Campbell 1978, Irvine et al. 1981). Manatees are widely dispersedalong the Gulf and Atlantic Coasts of the southeastern U.S. during the summermonths and aggregate at traditional warm water wintering sites during coolermonths (Hartman 1974, Powell and Waldron 1978, Rose and McCutcheon 1980,Rathbun et al. 1982, Powell and Rathbun 1983, Shane 1983). Their winterrange on the east coast of Florida extends as far north as Jacksonville(Hartman 1974, Rathbun et al. 1983, Kinnaird and Valade 1983) but manateesare sighted most frequently in the northeastern region of the peninsuladuring the summer months (Moore 1951, Hartman 1974, Irvine and Campbell1978). Recent evidence suggests that manatees in northeastern Florida arenot discrete subpopulations and that manatees make seasonal north/southmigrations along the eastern coastal waterways (Hartman 1974, Shane 1983,Rathbun et al. 1983, Kinnaird and Valade 1983).Northeastern Florida has the highest known manatee mortality in thestate, including the highest incidence of deaths due to collisions withboats, particularly in the St. Johns River and Brevard County (O'Shea et al.in prep.). It is difficult to develop wise management policies for thisregion because spatial and temporal use of northeastern Florida by manateeshas not been fully documented. The nature and extent of boat traffic alsohas not been described. I conducted aerial surveys for one complete year over the lower reachesof the St. Johns River and the northeastern section of the ICW (southernVolusia County to Kings Bay, Georgia) to document the spatial and temporalpatternLt~at characterize manatee use of northeast Florida, and to describethe nature and extent of boat traffic. The development of managementpractices based on these patterns should help minimize resource conflicts andpossibly reduce manatee boat/barge mortality. (60 page document)

    Description: This report documents breeding numbers, reproductive success, and foragingdispersion of long-legged wading birds in the Water Conservation Areas (WCAs) of theEverglades during the first six months of 1993. Briefly, the 1993 spring had abnormallyhigh water and windy conditions throughout the season, and produced poor nesting effort,low to moderate nesting success, and low production of young. Some species, like WoodStorks and White Ibises, did not nest at all in the WCAs. Others, like Great Egrets andTricolored Herons, showed considerably tenacity under the extremely poor nestingconditions. The 1993 season provided a rare chance to record the reproductive responses ofwading birds during sustained high water conditions. (108 page document)

    Description: This comprehensive final report summarizes the results of a four-year researchand monitoring effort (1998 - 2001) designed to document nesting effort and success bywading birds, and to investigate the reproductive physiology and ecology of White Ibises(Eudocimus albus) in the Everglades ecosystem. The monitoring of nesting has beenaccomplished bystandardized systematic aerial and ground surveys and study of nestingsuccess of nesting colonies in Water Conservation Areas (WCAs) 2 and 3 ofthe centralEverglades. The White Ibis work was accomplished through 1) investigation of thenutritional, behavioral, and hormonal aspects of "normal" breeding in a captive colony ofScarlet Ibises (Eudocimus ruber, considered by many to be the same species as the WhiteIbis), and 2) documenting the physiology, nutritional state, breeding phenology,contaminant load, and hormonal status of free- living adult White Ibises in the centralEverglades.

    Description: Fibropapillomatosis (FP) is a growing threat to the survival of green turtle,Chelonia mydas, populations worldwide and has been shown to be affectingloggerhead, Caretta caretta, and olive ridley, Lepidochelys olivacea, populations aswell. Transmission studies in captivity carried out by this laboratory have demonstratedthat FP in green turtles is caused by an infectious subcellular agent. (Herbst, et al,1995), (Herbst et ai, 1996a). We have demonstrated a new Chelonid herpesvirus inexperimentally induced and spontaneous fibropapillomas of green turtles using electronmicroscopic,molecular, and serological techniques (Jacobson et ai, 1991), (Herbst, etai, 1995), (Herbst, et ai, 1996b), (Lackovich, et al 1998a), (Herbst, et ai, 1998), (Garber,et al 1998). Recent studies by others have confirmed our early characterization of thisvirus as a member of the Alphaherpesvirinae subfamily (Quackenbush, et al, 1998,Herbst, et al, 1996b, Garber, et ai, 1998).Although this herpesvirus is considered a candidate for the etiology of FP, it hasnot yet been cultivated in vitro. Fulfillment of Koch's postulates through a controlledtransmission study using cultured herpesvirus would test its role as the etiologic agentof FP. These studies were initiated to provide previously unavailable information aboutthe prevalence of this virus in tumors and skin of green and loggerhead turtles in Floridaand to attempt to cultivate it in vitro.

    Description: Research conducted under this RWO from July 1, 1997 through June 30, 2000 hasprovided important new information about the pathogenesis, virology, andimmunology of marine turtle fibropapillomatosis. In particular, we have providedstrong evidence for the association of a herpesvirus with fibropapillomatosis of thegreen turtle,Chelonia mydas, and the loggerhead turtle, Caretta caretta, in Florida. Inaddition we have provided new evidence for the absence of papillomaviruses fromsea turtle fibropapillomas. Although unsuccessful, important new attempts were madeto cultivate the FP-associated herpesvirus in vitro in collaboration with the NationalWildlife Health Center. During this period of time, we completed publication of the firstcomprehensive description of the comparative pathology and pathogenesis ofexperimentally induced and spontaneous fibropapillomas of green turtles (Cheloniamydas). We initiated innovative studies on the persistence of a Chelonianherpesviruses in the marine environment demonstrating for the first time that theenvironmental survivability of Chelonian herpesviruses makes them real threats tomarine turtle health. Finally, we explored development of a serological assay for FPusing synthetic herpesvirus peptides and developed methodologies for detection ofantibodies to LETV [Iung-eye-trachea virus] a disease-associated herpesvirus of thegreen turtle, Chelonia mydas.. This last initiative is ongoing and will further our effortsto develop specific immunological assays for the FP-associated herpesvirus and FP. (17 page document)

    Description: Inlets are common coastal features around the world. Essentially aninlet connects a lagoon, a bay or an estuary to the ocean (or sea), and theflow through the inlet channel is primarily induced by the tidal rise andfall of water level in the ocean. When speaking of the hydraulics of an inlet,one is interested mainly in determining the flow through the inlet andthe tidal variation in the bay, given the following:(1) Inlet geometry(2) Bay geometry(3) Bottom sediment characteristics in the inlet(4) Fresh water inflow into the bay (and out throughthe inlet)(5) Ocean tide characteristicsA combination of all these factors can produce a rather complex situation.

Sediment budget methodology can beuseful in a number of coastal engineering and research applications,including: inferring the amount of onshore sediment transport for a nearshoresystem that contains an "excess of sediment", determining sediment deficits todowndrift beaches as a result of engineering works at navigational entrances,evaluating the performance of a beach nourishment project, inferring thedistribution of longshore sediment transport across the surf zone, etc.This chapter reviews briefly the governing equations for sediment budgetcalculations, considers various measurement and other bases for determiningthe sediment flux components necessary to apply the sediment budget conceptand finally for illustration purposes, applies the sediment budget concept toseveral examples.

    Description: A fixed-bed hydraulic model of Jupiter Inlet, Florida, wasconstructed for the purpose of testing measures designed to remedyproblems of sediment erosion and deposition in the inlet area. Bothtide-induced flows as well as waves were simulated in the model whichwas built on an undistorted scale of 1:49. Model verification was basedon prototype measurements of waves, tides and currents. Results havebeen interpreted in terms of the influence of various proposed remedialschemes on flow velocity magnitude, distribution and wave height atvarious locations within the study area. A stability parameter has beenutilized for evaluating the degree of sediment erosion or deposition ata given location.Various structural solutions were examined in the model. It isproposed that, in the initial phase of solution implementation, sedimentremoval/nourishment methods be used primarily to mitigate the existingproblems. New structures, as per model test results, should beinstalled under subsequent phases, only if sediment managementprocedures do not prove to be adequate. The currently followedprocedure of periodic sand trap dredging may be extended to include thenew dredging/nourishment requirements. (PDF contains 245 pages.)

    Description: Registered boats less than 26 feet in Florida have expanded from 449,995 in 1982 to 620,548 in 1993,a 38 percent increase. Boats of this size are likely to be trailered to boat ramps for access towater bodies in and around the state. This increased demand for boat ramps has been accompanied bymany studies and surveys indicating a need for more public boat ramps and that existing ramps needimprovement. This report covers boat ramp issues and boaters' willingness to pay for manatee protection. (106pp.)

    Description: The objectives of this study were 1) to determine the maximum structure-inducedlocal sediment scour depths for the proposed bridge piers for the Merrill BarberBridge over Indian River on.State Road 60 in Indian River County, Florida and 2) todetermine the feasibility of predicting equilibrium local scour depths near complexmultiple pile bridge piers from bottom shear stresses on the prescoured bed. Aseries of hydrodynamic tests were conducted in a laboratory flume (100 ft long x 8 ftwide x 2 ft deep) where flow velocities near model piers were measured with a twocomponent constant temperature anemometer at a height of 3 mm above the bed. Bottomshear stresses were then estimated from the flow measurements. The piers (which are1/15 scale models of proposed Merrill Barber Bridge piers) consisted of thirtysixsquare piles (3 columns of 12) and a pile cap that was positioned at differentelevations above the bottom. Two different pile cap shapes were also considered. Asimple relationship between the prescoured bottom shear stress and the equilibriumlocal scour depth was postulated.Sediment scour tests were then conducted in the same flume with the samemodels. The average duration of these tests was 28 hours. Scour depths weremeasured periodically throughout these tests using an acoustic transponder. Thescour measurements were used 1) to establish the maximum scour depths for the MerrillBarber Bridge piers and 2) to calibrate and test the scour-shear stress relationship.Even though the range of conditions tested was somewhat limited, the approach appearspromising and should be pursued further. A number of interesting findings were maderegarding the rate at which scour occurs in these complex structures. (Document contains 134 pages.)

    Description: This report presents the results of laboratory studies which were carried out in the Coastaland Oceanographical Engineering Laboratory to investigate the effects of ground water tableelevations on the beach profile changes over the swash zone. The experiment was conducted atthree different water table levels while the other experimental conditions were fixed to constantvalues with regular waves. The water table levels included (1) normal water table level whichis the same as mean sea level, (2) a higher level and (3) a lower level than the mean sealevel. Special attention was given to the higher water level to investigate whether this levelenhances erosion of the beach face and also to methods of interpreting the experimental data.The experiment described herein was carried out with a fairly fine sand and has demonstratedthe significance of beach water table on profile dynamics. The increased water table levelcaused distinct effects in three definite zones. First, erosion occurred at the base of the beachface and the sand eroded was carried up and deposited on the upper portion of the beachface. Secondly, the bar trough deepened considerably and rapidly and the eroded sand wasdeposited immediately landward. This depositional area changed from mildly erosional tostrongly depositional. Third, the area seaward of the bar eroded with a substantial deepening.The lowered water table appeared to result in a much more stable beach and the resultingeffects were much less. The only noticeable trend was a limited deposition in the scour area atthe base of the beach face. (Document has 37 pages.)

    Description: The focus of this study was the flow patterns of a flood tide near an inlet. The objectiveswere to examine flood flow patterns with particular reference to non-uniform or selectivewithdrawal as influenced by bottom topography and longshore currents, and to test theapplicability of conceptually simple analytic solutions to realistic sandy inlet bottom topographies,which often include an ebb shoal. Specifically, the applicability of three analytic solutions, twoof which include offshore selective withdrawal, to modeling of tidal water withdrawal duringflood tide under variable bottom topography and varying ratios of longshore current to inletvelocity, was examined. The three analytic solutions, including those for a horizontal (flat)bottom, a linearly sloping bottom and a logarithmically sloping bottom, together with a uniformlongshore current, were derived using potential flow theory. These solutions exhibit uniformlydistributed flows, selective offshore withdrawal, or an exaggerated offshore withdrawal,respectively, depending on the bottom slope. In order to investigate the flow patterns that exist during flood flow at a real inlet, experiments were conducted in a fixed bed hydrodynamic modelof Jupiter Inlet, Florida. Measurements were made to determine streamlines and velocities. Afield study at the prototype also tracked drogue patterns to determine streamlines and velocities.The physical model tests compared well with the field data. Comparison of thelaboratory and field data was then made to the analytic solutions to determine whether thetopography at Jupiter Inlet, which includes a well-developed ebb shoal, simulates a flat, meanlinearly or logarithmically sloping bottom. By comparing velocities at six selected points, asignificant relationship between the physical model and field data to the flat bottom analyticsolution was evident. The physical model tests and field data suggested that the flood tidal prismwas drawn from the region predominantly shoreward of the ebb shoal, thus implying a nearshoreselective withdrawal. Because the flood tidal prism was drawn from the nearshore, the flowpatterns at Jupiter Inlet did not resemble the analytic solutions of a linearly or logarithmicallysloping bottom, even though over a relatively long distance offshore, the bottom topography doesslope offshore at this inlet. In general, different inlet topographies would lend themselves todifferent analytic solutions, two examples being 1) the linearly sloping bottom of Koombana BayInlet, Australia, which shows an offshore selective withdrawal and 2) the basin-like nearfieldtopography of Jupiter Inlet which shows a more uniform nearshore withdrawal. The implicationsof this study are relevant to inlet management issues such as the mining of an ebb shoal for useas a source of beach sediment and changes in larval transport patterns due to jetty modifications.

    Description: During 1983 and 1984 the effect of low level military trainingflights on the establishment. size and reproductive success of wadingbird colonies was studied in Florida. Based on the indirect evidenceof colony distributions and turnover rates in relation to militaryareas (training routes designated to 500 feet or less above groundlevel and military operations areas). there was no demonstrated effectof military activity on wading bird colony establishment or size on astatewide basis. Colony distributions were random with respect tomilitary areas and turnover rates were within 2% when military andnon-military areas were compared. Colony distributions and turnoverrates, however. were related to the amount and type.Les tuer-tne orfreshwater) of wetland. respectively.During two breeding seasons the behavioral responses andreproductive success of selected species were monitored in anon-habituated treatment colony (military overflights) and a controlcolony (no overflights). Breeding wading birds responded to F-16overflights at 420 knots indicated airspeed. 82-84% maximum rpm. 500feet above ground level and sound levels ranging from 55-100 dBA byexhibiting no response. looking up or changing position (usually to analert posture): no productivity limiting responses were observed.High-nesting Great Egrets responded more than other species, nestlingGreat Egrets and Cattle Egrets responded significantly (r 〈.05) moreintensely than adults of their respective species, and adultsresponded less during incubation and late chick-rearing than at othertimes. In addition, no differences in adult attendance, aggressiveinteractions or chick feeding rates were observed to result from F-16 overflights. No evidence of habituation to overflights was noted.Humans entering the colony or airboats approaching the colony vicinityelicited the most severe responses (flushing and panic flights)observed at both sites.Since relatively little coastal military activity occurs at lowlevels ( ~500 ft) and only one Brown Pelican colony (5-6% of thebreeding population) was located in such an area, the reproductivesuccess of five, more lIexposedll study species (Great Egrets, SnowyEgrets, Tricolored Herons, Little Blue Herons, Cattle Egrets) nestingin interior freshwater colonies was studied. Reproductive activityincluding such factors as nest success, nestling survival, nestlingmortality, and nesting chronology was independent of F-16 overflightsbut related to ecological factors including colony location, colonycharacteristics and climatology. The responses to and effects of F-16overflights, as reported here, should not be considered representativeof military aircraft at lower altitudes or greater noise levels. (194 pages)

    Description: We have developed immunological tests that can identify marine turtles in Florida (green and loggerhead) that have been exposedto the LETV herpesvirus. The seroepidemiological data collected provides critical evidence about the relationship betweeninfection with the FP-associated herpesvirus and the LETV herpesvirus. The data supports the hypothesis that LETV and FPHVinfections are independent infections of marine turtles. The data shows that wild green turtles in Florida are exposed to theLETD-associated herpesvirus, which is the first description ofLETV infection in free-ranging marine turtles. To our knowledge,the antigenic proteins identified in this study are not only the first proteins from a reptilian herpesvirus to be cloned andexpressed, but they represent the first reptilian herpesvirus proteins to be identified as immunogenic in their host species.

    Description: To predict the hydrodynamics of lakes, estuaries and shallow seas, a two 'dimensionalnumerical model is developed using the method of fractional steps. Thegoverning equations, i.e., the vertically integrated Navier-Stokes equations of fluidmotion, are solved through three steps: advection, diffusion and propagation. Thecharacteristics method is used to solve the advection, the alternating direction implicitmethod is applied to compute the diffusion, and the conjugate gradient iterativemethod is employed to calculate the propagation. Two ways to simulatethe moving boundary problem are studied. The first method is based on the weirformulation. The second method is based on the assumption that a thin water layerexists over the entire dry region at all times. A number of analytical solutions areused to validate the model. The model is also applied to simulate the wind drivencirculation in Lake Okeechobee, Florida.(135 page document)

    Description: Inlets which require frequent channel dredging due to gradual shoaling,exhibit migration, or shoal up during storms, are in general unstable andpose a problem to the engineer. This problem of inlet stability is a complexone, because of the rather large number of variables that go into definingstability. The reference here is to inlets on sandy coasts only, becausethe absence of sand or similar sedimentary material the problem does notarise. Shell is also found in varying proportions with sand. Some of thisis. new, whereas in some areas it is ancient reworked material whose sizedistribution is close to that of the sand with which it is associated. (PDF has 24 pages.)

    Description: Part I. Relationships between the rate of bed fluidization and the rate of wave energy dissipation, by Jingzhi Feng and Ashish J. Mehta and Part II. In-situ rheometry for determining the dynamic response of bed, by David J.A. Williams and P. Rhodri Williams.A series of preliminary laboratory flume experiments were carried out to examine the time-dependentbehavior of a cohesive soil bed subjected to progressive, monochromatic waves. The bed was an aqueous,50/50 (by weight) mixture of a kaolinite and an attapulgite placed in a plexiglass trench. The nominal bedthickness was 16 cm with density ranging from 1170 to 1380 kg/m 3, and water above was 16 to 20 cmdeep. Waves of design height ranging from 2 to 8 cm and a nominal frequency of 1 Hz were run fordurations up to 2970 min. Part I of this report describes experiments meant to examine the rate at whichthe bed became fluidized, and its relation to the rate of wave energy dissipation. Part II gives results onin-situ rheometry used to track the associated changes in bed rigidity.Temporal and spatial changes of the effective stress were measured during the course of wave action,and from these changes the bed fluidization rate was calculated. A wave-mud interaction model developedin a companion study was employed to calculate the rate of wave energy dissipation. The dependence ofthe rate of fluidization on the rate of energy dissipation was then explored.Fluidization, which seemingly proceeded down from the bed surface, occurred as a result of the lossof structural integrity of the soil matrix through a buildup of the excess pore pressure and the associated loss of effective stress. The rate of fluidization was typically greater at the beginning of wave action andapparently approached zero with time. This trend coincided with the approach of the rate of energydissipation to a constant value. In general it was also observed that, for a given wave frequency, the largerthe wave height the faster the rate of fluidization and thicker the fluid mud layer formed. On the otherhand, increasing the time of bed consolidation prior to wave action decreased the fluidization rate due togreater bed rigidity. Upon cessation of wave action structural recovery followed.Dynamic rigidity was measured by specially designed, in situ shearometers placed in the bed atappropriate elevations to determine the time-dependence of the storage and loss moduli, G' and G", ofthe viscoelastic clay mixture under 1 Hz waves. As the inter-particle bonds of the space-filling, bedmaterial matrix weakened, the shear propagation velocity decreased measurably. Consequently, G'decreased and G" increased as a transition from dynamically more elastic to more viscous responseoccurred. These preliminary experiments have demonstrated the validity of the particular rheometrictechnique used, and the critical need for synchronous, in-situ measurements of pore pressures and modulicharacterizing bed rheology in studies on mud fluidization.This study was supported by WES contract DACW39-90-K-0010.(This document contains 151 pages.)

    Description: With the rapid growth and development of barrier islands, understanding the long-termstability of these islands is an integral part of future coastal planning. The overwash process isthe largest influence on the long-term stability of these islands and thus a correspondingunderstanding is of major importance. A laboratory experiment was undertaken to physicallymodel the wave and current forcing as they pertain to the overwash process. The physical modelwas subjected to various storm conditions common to the occurrence of the overwash.Combinations of wave height, wave period, and overwash depth were tested in an attempt toisolate the significant parameters. Water surface gradients were also applied to observe theirinfluence on the overwash process. Wave height, current, and bed profile measurements weretaken at different locations throughout the tank. In addition, wave height transformationmodeling and mean current prediction were performed and compared to the laboratory results inan attempt to model the overwash process through computer simulations.

    Description: The mechanism by which fluid mud is formed by water wave motion over coastal andestuarine cohesive soil beds is of evident interest in understanding and interpreting themicrofabric of flow-deposited fine sediments in shallow waters, and hence the erodibilityof muddy beds due to hydrodynamic forcing. This study investigated water wave-inducedfluidization of cohesive soil beds composed of a 50/50 (by weight) mixture of a commercialattapulgite and a kaolinite in a laboratory flume. Temporal and spatial changes of theeffective stress were measured during the course of wave action, and from these changesthe bed fluidization rate was calculated. A previously developed hydrodynamic wave-mudinteraction model of the two-layered water-mud system was employed to study the natureand the degree of wave dissipation, in terms of energy dissipation rate, during the bed fluidizationprocess. By evaluating the mud rheological properties separately, a mud viscositymodel was developed, which was then used in conjunction with the wave-mud interactionmodel to obtain an effective sheared thickness of the bed resulting from wave action. Thisthickness, considered to be a representative of the fluidized mud thickness, was comparedwith the latter obtained from pressure measurements. Also, through this wave-mud modelthe relationship between the rate of fluidization and the rate of wave energy dissipationduring fluidization was examined. In general, for a given wave frequency, a larger wave fluidized the bed at a faster rateand to a greater depth than a smaller one. Furthermore, increased bed consolidation timedecreased the rate of fluidization due to increased mud rigidity. The rate of bed fluidizationwas typically greater at the beginning of wave action and decreased with time. Eventuallythis rate approached zero, while in some cases the wave energy dissipation rate approached aconstant value, which increased with wave height. As the fluidization rate approached zero,there appeared to occur an equilibrium value of the bed elevation, and hence a fluid mudthickness, for a given wave condition. During the fluidization process the bed apparentlylost its structural integrity by loss of the effective stress through a build-up of the excesspore water pressure. After wave action ceased, the bed structure exhibited recovery bydissipation of the excess pore water pressure.Further studies will be required in which the hydrodynamic model must be improved viaa more realistic description of mud rheology and relaxation of the shallow water assumption,and better pressure data must be obtained than in the present study. Nevertheless, thisinvestigation has been instructive in demonstrating relationships between the degree of mudfluidization, wave energy dissipation and bed consolidation time, and thus offers insight intoan important mechanism by which coastal and estuarine muds are eroded by wave action.

    Description: In this final report on the investigation of the potentialities of improvedcoastal engineering management of Jupiter Inlet, Florida, three management-guidingissues were considered: better control of the erosion of the south beach, betternavigation access and safety, and better control (reduction) of sediment influx into theinlet channel and upstream points in the Loxahatchee River estuary. The first twoissues have been particularly outstanding, due to persistent concern for the inherentdeficiencies in the protocol for sand pumping and placement on the beach that tends toerode away rapidly, and the concern for conditions for navigation of vessels in theproximity of the inlet in open waters. With regard to the third issue, despite thereasonably successful ongoing program to pump sand out of the borrow areas within theinlet channel, other areas such as some of the marinas in the inlet area, as well as theregion of the Loxahatchee River west of the Florida East Coast Railroad bridge, havebeen experiencing slow but persistent sedimentation.Contingent upon a series of coastal and environmental engineering investigations,a range of engineering actions that could mitigate erosion, navigation and sedimentationproblems were considered. Based on the physical and ecological impacts that would becaused by these actions, two sets of action options that have net beneficial impacts dueto action implementation have been proposed. The first is a set of interdependentaction options that must be instituted inherently in a time-wise phased manner. Thesecond is a set of independent action options which can be instituted as and when desired. For determining the overall feasibility of any action option, it will benecessary to weigh the technical benefits against costs, which are provided. It shouldbe emphasized however that, considering the overwhelmingly observational nature ofcoastal science, the estimates of potential benefits are essentially and inherentlysubjective, and the costs very approximate, especially in cases where the desiredtechnology is in the "bench" stage.
