    Description: Daily sea surface temperatures have been acquired at the Hopkins Marine Station in Pacific Grove, California since January 20, 1919.This time series is one of the longestoceanographic records along the U.S. west coast. Because of its length it is well-suited for studying climate-related and oceanic variability on interannual, decadal, and interdecadal time scales. The record, however, is not homogeneous, has numerous gaps, contains possible outliers, and the observations were not always collected at the same time each day. Because of these problems we have undertaken the task of reconstructing this long and unique series.We describe the steps that were taken and the methods that were used in this reconstruction. Although the methods employed are basic, we believe that they are consistent with the quality of the data. The reconstructed record has values at every time point, original, or estimated, and has been adjusted for time-of-day variations where this information was available. Possible outliers have also been examined and replaced where their credibility could not be established. Many of the studies that have employed the Hopkins time series have not discussed the issue of data quality and how these problems were addressed. Because of growing interest in this record, it is important that a single, well-documented version be adopted, so that the results of future analyses can be directly compared. Although additional work may be done to further improve the quality of this record, it is now available via the internet. [PDF contains 48 pages]

Principal subjects covered in this paper include a definition of marine habitat improvement and determination of its attainment, the present applications of reef construction technology to environmental situations both generally and in three case-studies, and suggested desirable attributes for incorporation into future use of this technology. (PDF has 11 pages.)
    Description: Authors’ note: This document was the basis for a keynote presentation at the 2004 World Fisheries Congress, in a session on Marine Fisheries Habitat Improvement. Several of the slides shown there are included here, without captions.

    Description: Increased boating activities and new waterfront developments have contributed anestimated 3,000 dismantled, abandoned, junked, wrecked, derelict vessels to Floridacoastal waters. This report outlines a method of siting and prioritizing derelict vesselremoval using the Florida Keys as a test area. The data base was information on 240vessels, obtained from Florida Marine Patrol files. Vessel location was plotted on 1:250,000regional and 1:5,000 and 1:12,000 site maps. Type of vessel, length, hull material, engine,fuel tanks, overall condition, afloat and submerged characteristics, and accessibility, wereused to derive parametric site indices of removal priority and removal difficulty.Results indicate 59 top priority cases which should be the focus of immediate cleanup efforts in the Florida Keys. Half of these cases are rated low to moderate in removaldifficulty; the remainder are difficult to remove. Removal difficulty is a surrogate forremoval cost: low difficulty -low cost, high difficulty - high cost. The rating scheme offerscoastal planners options of focusing removal operations either on (1) specific areas withclusters of high priority derelict vessels or on (2) selected targeted derelicts at various,specific locations.

    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: 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.
