Winter And Summer Sediment Nutrient Exchange Rates In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

Winter and summer in-situ measurements of sediment oxygen demand (SOD) and nutrient exchange rates (NERs) were taken from sandy and muddy sediments in Hillsborough Bay during 1986. The summer-mud SOD rate of 0.23 g 02/m²/hr was roughly twice the summer-sand, winter-sand and winter-mud SOD rates. In general, nutrient flux rates into the water column were usually greater from mud relative to sand, and during the summer compared to the winter. Reservations in the application of the SOD/NER data and recommendations for future SOD/NER measurements are discussed.

Ecological Assessment, Classification And Management Of Tampa Bay Tidal Creeks, Tampa Bay Regional Planning Council (Tbrpc)

Reports

The final product is a detailed restoration and management plan for three minor tributaries in the Tampa Bay watershed and one general application. It is the intent of the Council to implement all elements of the four plans wherever feasible during Developments of Regional Impact (DRI's) and Intergovernmental Coordination and Review (IC&R) reviews and through coordinat.ion with the DNR gill-net license fee habitat restoration program, as well as local government initiatives. The efforts of the Council's Agency on Bay Management will also be critical in implementing the findings and recommendations of this project.

Preliminary Study Of The Seagrasses In Middle Tampa Bay Between Apollo Beach And Simmons Park, Mangrove Systems, Inc.

Reports

Comparison of recent (1986) and earlier (1983) aerial photography indicated that an apparent recovery of seagrasses was occurring on the subtidal shelf north of Simmons Park (Ruskin) and south of Apollo Beach, in Middle Tampa Bay (Fig. 1). This was suggested by the numerous circular patches of grass observed on the offshore portions of the shelf. This observation provided the incentive to undertake a preliminary assessment of seagrass species composition, percent cover, and shoot density along transects in this area. This study was a cooperative effort between the Bay Study Program (City of Tampa) and Mangrove Systems, Inc.

1986 Florida Water Quality Assessment 305(B) Technical Report, Joe Hand, Victoria Tauxe, John Watts, Bureau Of Water Quality Management - Division Of Environmental Programs

Reports

This report identifies the quality and trends of Florida's surface waters, the causes of water quality problems and the present cleanup activities conducted by DER and EPA to improve these problem areas. The assessment was accomplished by analyzing the available STORET water quality data for the 1970-1985 time period (STORET is EPA's computerized water quality data base). Data from approximately 97,000 water quality samples were assessed in this report which necessitated the extensive use of computer analysis. The computer analysis required assigning STORET stations to their respective EPA reaches. The EPA reach designation is a convenient national numbering system similar …

Winter Sediment Nutrient Exchange Rates In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

The winter sampling of the sediment nutrient exchange rate study of Hillsborough Bay has been completed. These results constitute the interim report of the winter nutrient exchange sampling of Phase II as described in the Plan of Study submitted to the Florida Department of Environmental Regulation on March 31, 1986. The results include winter SOD rate estimates in sandy and muddy sediments. Results also include winter NER estimates in sandy and muddy sediments for total phosphorus (unfiltered), PO₄-P, TKN (unfiltered), NO₂-N+NO₃-N, NH₃-N and organic N. These data, in conjunction with the forthcoming …

A Study Plan Of Sediment Nutrient Exchange Rates In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

The City of Tampa is planning a study of sediment nutrient exchange rates in Hillsborough Bay, Florida. The study will supply the FDER Water Quality Analysis Section with information to refine the mathematical modeling of Hillsborough Bay for wasteload allocation. The initial effort, Phase I, will produce a map of Hillsborough Bay identifying areas of "sandy" and "muddy" sediments, and to estimate the areal coverage of these sediment types. The secondary effort, Phase II, will estimate seasonal nutrient exchange rates for "sandy" and "muddy" sediments at a minimum of two locations in Hillsborough Bay. The seasonal estimates of sediment nutrient …

Surface Sediment Composition And Distribution In Hillsborough Bay, Florida 1986, City Of Tampa Department Of Sanitary Sewers Bay Study Group

Reports

Surface sediments were mapped to determine the approximate boundaries and percent areal coverage of "mud" in Hillsborough Bay. Depth recorder soundings along 29 transects were used in conjunction with sediment grain size analyses form 19 stations to produce a sediment map.

A Survey Of Potential Problems Related To Toxic Organic Chemical Contamination Of Aquatic Environments, Carol B. Rideout, Michael E. Bender

Reports

Toxic organic chemicals have affected aquatic resources by (1) restricting harvest; (2) causing biological damage to harvestable stocks; and (3) damaging other biological resources eg. benthic animals and birds.
