    Description: The possible ecological effects of suspended sediments are manifold. Briefly, suspended sediments may cause an increased surface for microorganism growth, fewer temperature fluctuations, chemical adsorption orabsorption, blanketing, mechanical-abrasive actions, and light penetration reduction (Cairns, 1968). Sherk and Cronin (1970) have pointed out that the above effects have been little studied in the estuarine environment. The ecological effects of suspended sediments on fish eggs and larvae may be of prime importance t o the C and D Canal area, an important spawning and primary nursery area for a variety of estuary: e species (Johnson,1972). This section discusses the effects of suspended sediment on the eggs and larvae of striped bass and white perch.

    Description: A number of wells penetrating the Floridan aquifer in easternClay County were found to be losing water to permeable zones abovethis aquifer. A differential in artesian pressure was observed in closelyspaced wells of similar depth. Further investigation. revealed thatthe pressure differential in the wells was due to the design of thewells, of which there were four principal types.A comparison of the four types of wells in relation to the subsurfacegeology showed that three types of wells were open to the permeablezones above the Floridan aquifer. In such wells water of relativelyhigh head from the Floridan aquifer moves up through the well boreand out into zones of relatively low head.The estimated water loss from poorly designed wells rangedfrom 32 to 180 gpm (gallons per minute). The artesian head loss inleaky wells ranged from 3 to 15 feet. A total loss of water of 39 mgd(million gallons per day) was estimated from all the leaky wells inthe area. A significant decline of the piezometric surface of the Floridanaquifer was observed in eastern Clay County. Some of this decline canbe attributed to the loss of water from the Floridan aquifer throughthese poorly designed wells. (Document has 16 pages.)

    Description: The ACT workshop "Enabling Sensor Interoperability" addressed the need for protocols at thehardware, firmware, and higher levels in order to attain instrument interoperability within and betweenocean observing systems. For the purpose of the workshop, participants spoke in tern of "instruments" rather than "sensors," defining an instrument as a device that contains one or more sensors or actuators and can convert signals from analog to digital.An increase in the abundance, variety, and complexity of instruments and observing systems suggeststhat effective standards would greatly improve "plug-and-work" capabilities. However, there are few standards or standards bodies that currently address instrument interoperability and configuration.Instrument interoperability issues span the length and breadth of these systems, from the measurementto the end user, including middleware services. There are three major components of instrumentinteroperability including physical, communication, and application/control layers. Participantsidentified the essential issues, current obstacles, and enabling technologies and standards,then came up with a series of short and long term solutions.The top three recommended actions, deemed achievable within 6 months of the release of thisreport are:A list of recommendations for enabling instrument interoperability should be put togetherand distributed to instrument developers.A recommendation for funding sources to achieve instrument interoperability should bedrafted. Funding should be provided (for example through NOPP or an IOOS request forproposals) to develop and demonstrate instrument interoperability technologies involvinginstrument manufacturers, observing system operators, and cyberinfrastructure groups.Program managers should be identified and made to understand that milestones for achievinginstrument interoperability include a) selection of a methodology for uniquely identifyingan instrument, b) development of a common protocol for automatic instrumentdiscovery, c) agreement on uniform methods for measurements, d) enablement of end usercontrolled power cycling, and e) implementation of a registry component for IDS and attributes.The top three recommended actions, deemed achievable within S years of the release of this reportare:An ocean observing interoperability standards body should be established that addresses standards for a) metadata, b) commands, c) protocols, d) processes, e) exclusivity, and f)naming authorities.[PDF contains 48 pages]

    Description: The co-organized Alliance for Coastal Technologies (ACT) and National Data Buoy Center (NDBC)Workshop "Meteorological Buoy Sensors Workshop" convened in Solomons, Maryland, April 19to 21,2006, sponsored by the University of Maryland Center for Environmental Science (UMCES)Chesapeake Bay Laboratory (CBL), an ACT partner institution. Participants from various sectorsincluding resource managers and industry representatives collaborated to focus on technologies andsensors that measure the near surface variables of wind speed and direction, barometric pressure,humidity and air temperature. The vendor list was accordingly targeted at companies that producedthese types of sensors. The managers represented a cross section of federal, regional and academicmarine observing interests from around the country. Workshop discussions focused on the challengesassociated with making marine meteorological observations in general and problems that werespecific to a particular variable. Discussions also explored methods to mitigate these challengesthrough the adoption of best practices, improved technologies and increased standardization. Someof the key workshop outcomes and recommendations included:0cean.US should establish a committee devoted to observations. The committee wouldhave a key role in developing observing standards.The community should adopt the target cost, reliability and performance standards draftedfor a typical meteorological package to be used by a regional observing system.A forum should be established to allow users and manufacturers to share best practicesfor the employment of marine meteorological sensors. The ACT website would host theforum.Federal activities that evaluate meteorological sensors should make their results publiclyavailable.ACT should extend their evaluation process to include meteorological sensors.A follow on workshop should be conducted that covers the observing of meteorologicalvariables not addressed by this workshop.

    Description: The Alliance for Coastal Technologies (ACT) convened a workshop on Evaluating Approaches and Technologies for Monitoring Organic Contaminants in the Aquatic Environment in Ann Arbor, MI on July 21-23, 2006. The primary objectives of this workshop were to: 1) identify the priority management information needs relative to organic contaminant loading; 2) explore themost appropriate approaches to estimating mass loading; and 3) evaluate the current status of thesensor technology. To meet these objectives, a mixture of leading research scientists, resourcemanagers, and industry representatives were brought together for a focused two-day workshop.The workshop featured four plenary talks followed by breakout sessions in which arranged groupsof participants where charged to respond to a series of focused discussion questions.At present, there are major concerns about the inadequacies in approaches and technologies forquantifying mass emissions and detection of organic contaminants for protecting municipal watersupplies and receiving waters. Managers use estimates of land-based contaminant loadings torivers, lakes, and oceans to assess relative risk among various contaminant sources, determinecompliance with regulatory standards, and define progress in source reduction. However, accuratelyquantifying contaminant loading remains a major challenge. Loading occurs over a range ofhydrologic conditions, requiring measurement technologies that can accommodate a broad rangeof ambient conditions. In addition, in situ chemical sensors that provide a means for acquiringcontinuous concentration measurements are still under development, particularly for organic contaminantsthat typically occur at low concentrations. Better approaches and strategies for estimatingcontaminant loading, including evaluations of both sampling design and sensor technologies,need to be identified. The following general recommendations were made in an effort to advancefuture organic contaminant monitoring:1. Improve the understanding of material balance in aquatic systems and the relationship betweenpotential surrogate measures (e.g., DOC, chlorophyll, particle size distribution) and target constituents.2. Develop continuous real-time sensors to be used by managers as screening measures and triggersfor more intensive monitoring.3. Pursue surrogate measures and indicators of organic pollutant contamination, such as CDOM,turbidity, or non-equilibrium partitioning.4. Develop continuous field-deployable sensors for PCBs, PAHs, pyrethroids, and emerging contaminantsof concern and develop strategies that couple sampling approaches with tools that incorporatesensor synergy (i.e., measure appropriate surrogates along with the dissolved organics toallow full mass emission estimation).[PDF contains 20 pages]

    Description: The Alliance for Coastal Technologies (ACT) Workshop "Making Oxygen MeasurementsRoutine Like Temperature" was convened in St. Petersburg, Florida, January 4th - 6th, 2006. Thisevent was sponsored by the University of South Florida (USF) College of Marine Science, anACT partner institution and co-hosted by the Ocean Research Interactive Observatory Networks(ORION). Participants from researcldacademia, resource management, industry, and engineeringsectors collaborated with the aim to foster ideas and information on how to make measuringdissolved oxygen a routine part of a coastal or open ocean observing system.Plans are in motion to develop large scale ocean observing systems as part of the US IntegratedOcean Observing System (100s; see http://ocean.us) and the NSF Ocean Observatory Initiative(001; see http://www.orionprogram.org/00I/default.hl). These systems will require biologicaland chemical sensors that can be deployed in large numbers, with high reliability, and forextended periods of time (years). It is also likely that the development cycle for new sensors issufficiently long enough that completely new instruments, which operate on novel principles,cannot be developed before these complex observing systems will be deployed. The most likelypath to development of robust, reliable, high endurance sensors in the near future is to movethe current generation of sensors to a much greater degree of readiness. The ACT OxygenSensor Technology Evaluation demonstrated two important facts that are related to the need forsensors. There is a suite of commercially available sensors that can, in some circumstances,generate high quality data; however, the evaluation also showed that none of the sensors were ableto generate high quality data in all circumstances for even one month time periods due tobiofouling issues.Many groups are attempting to use oxygen sensors in large observing programs; however, thereoften seems to be limited communication between these groups and they often do not have accessto sophisticated engineering resources. Instrument manufacturers also do not have sufficientresources to bring sensors, which are marketable, but of limited endurance or reliability, to ahigher state of readiness. The goal of this ACT/ORION Oxygen Sensor Workshop was to bringtogether a group of experienced oceanographers who are now deploying oxygen sensors inextended arrays along with a core of experienced and interested academic and industrialengineers, and manufacturers. The intended direction for this workshop was for this group toexchange information accumulated through a variety of sensor deployments, examine failuremechanisms and explore a variety of potential solutions to these problems. One anticipatedoutcome was for there to be focused recommendations to funding agencies on development needsand potential solutions for 02 sensors. (pdf contains 19 pages)

    Description: In recent years, difficulties encountered in obtaining ground-water supplieswith acceptable chemical characteristics in the Myakka River basin area led tothe implementation of a test drilling program. Under this program, well drillingand data collection were executed in such a manner that all water-producingzones of the local aquifers, together with the quality and quantity of the wateravailable, were effectively identified.A step-drilling method was utilized which allowed the collection offormation cuttings, water samples, and water-level data, from isolated zones inthe well as drilling proceeded. The step drilling procedure is described. Thedriller's logs, geophysical logs, and chemical quality of water tables arepresented.(Document has 66 pages.)

    Description: Charlotte, De Soto, and Hardee counties are east-southeast ofTampa in west-central peninsular Florida, figure 1. In order toplan the future water-resource development of the area, informationabout the water resources is needed. To meet this need, the WaterResources Division of the U.S. Geological Survey, in cooperationwith the Peace River Basin Board of the Southwest Florida WaterManagement District as part of the statewide cooperative programwith the Division of Geology, Florida Board of Conservation, begana continuing hydrologic data collection program in July, 1963, asan initial step in the investigation and evaluation of the groundwaterresources of Hardee and De Soto counties. A similar hydrologicdata program commenced in Charlotte County in July, 1964.Previous work in Hardee and De Soto counties included aone year reconnaissance by the Division of Water Resources andConservation, Florida Board of Conservation, which concluded inJune, 1963, and resulted in a hydrologic report (Woodard, 1964).As an outgrowth of the hydrologic data program, a Map Seriesreport portraying the chemical character of water in the Floridanaquifer in the southern Peace River basin was prepared in 1967(Kaufman and Dion).The data contained herein constitute the basis for the MapSeries report. Additional selected data, including records of wellsand chemical analyses,, on the ground-water resources of the threecounty area are also included and are published to make the dataavailable.(Document has 28 pages.)
