Biscayne Bay was selected by NOAA for this survey because data from the NS&T Mussel Watch Program and data from previous surveys of the bay had shown a potential for toxicity and other adverse biological effects. In addition, no bay-wide information had been generated on the toxicological condition of the bay sediments and several agencies had indicated a need for this type of data and a willingness to assist NOAA in collecting them. The study area was defined as extending from Dumbfoundling Bay at the north end to Little Card Sound at the south end, seaward to the barrier islands or reef, and landward to the shoreline or saltwater control structures. This area was determined to encompass a total of 484 kilometers of the sea floor. During 1995 and 1996, 226 samples were collected from randomly-chosen locations and tested for toxicity and analyzed for chemical concentrations. Data from these tests and analyses are included in the report. Samples for benthic community analyses were collected at one-third of the stations; however, data from those analyses are not included in the report but are available from NOAA's online database http://nbi.noaa.gov/mapBiscaynebay.aspx.The survey was designed to characterize sediment quality throughout the greater Biscayne Bay area. Surficial sediment samples were collected during 1995 and 1996 from 226 randomly-chosen locations throughout nine major regions. Laboratory toxicity tests were performed as indicators of potential ecotoxicological effects in sediments. A battery of tests was performed to generate information from different phases (components) of the sediments. Tests were selected to represent a range in toxicological endpoints from acute to chronic sublethal responses. Toxicological tests were conducted to measure: reduced survival of adult amphipods exposed to solid-phase sediments; impaired fertilization success and abnormal morphological development in gametes and embryos, respectively, of sea urchins exposed to pore waters; reduced metabolic activity of a marine bioluminescent bacteria exposed to organic solvent extracts; induction of a cytochrome P-450 reporter gene system in exposures to solvent extracts; and reduced reproductive success in marine copepods exposed to solid-phase sediments.The full report is available online at http://www8.nos.noaa.gov/cit/nsandt/download/documents/BI1/BI1_report.pdf Specific objectives of the study were to: (1) determine the incidence and degree of toxicity of sediments throughout the study area;(2) determine the spatial patterns (or gradients) in chemical contamination and toxicity, ifany, throughout the study area;(3) determine the spatial extent of chemical contamination and toxicity;(4) determine the statistical relationships between measures of toxicity and concentrations of chemical substances in the sediments.The dataset objective is to report information about chemical residues in sediment, sediment toxicity, and benthic infauna characteristics of the system. completed National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA) National Status and Trends Program 301-713-3028 301-713-4388 1305 East West Highway - N/SCI-1 Silver Spring MD 20910 USA John.Christensen@noaa.gov pointOfContact notPlanned CoRIS_Metadata theme NCEI Geoportal Filter Environmental Monitoring theme NOS Data Explorer Topic Category Site station location latitude longitude date estuary region state parameter sediment chemical benthic infauna sediment chemical contaminants inorganic organic analytes polynuclear aromatic hydrocarbons PAH polychlorinated biphenyls PCB organochlorines pesticides toxicity bioassay amphipod Microtox sea urchin fertilization P450 human reporter gene system national status and trends nsandt NS&T theme None Numeric Data Sets > Chemical Contaminants theme CoRIS Discovery Thesaurus EARTH SCIENCE > Human Dimensions > Environmental Impacts > Contaminants theme CoRIS Theme Thesaurus Biscayne Bay Florida Southeast Coast of the United States United States place None OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida COUNTRY/TERRITORY > United States of America > Florida place CoRIS Place Thesaurus Florida place CoRIS Region These data were prepared by an agency of the United States Government.

The components of these totals are as follows:Total DDT = sum of concentrations of ortho and para forms of parent and metabolites 2,4'DDE; 4,4'DDE; 2,4'DDD; 4,4'DDD; 2,4'DDT and 4,4'DDT.Total Chlordane = sum of concentrations of four compounds alpha-chlordane, trans-nonachlor, heptachlor, heptachlorepoxide.Total Dieldrin = sum of concentrations of two compounds aldrin and dieldrin.Total Butyl tin = sum of concentrations of parent compound and metabolites monobutyltin, dibutyltin, tributyltin, tetrabutyltin [concentrations are in terms of tin].Total PCB = the sum of the concentrations of eighteen congeners: PCB8, PCB18, PCB28, PCB44, PCB52, PCB66, PCB101, PCB105, PCB118, PCB128, PCB138, PCB153, PCB170, PCB180, PCB187, PCB195, PCB206, and PCB209.Total low molecular weight (lmw) PAHs = sum of concentrations of twelve 2- and 3-ring PAH compounds: naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, biphenyl, 2,6-dimethylnaphthalene, acenaphthene, acenaphthylene, 1,6,7-trimehtylnaphthalene, fluorine, phenanthrene, 1-methylphenanthrene, and anthracene.Total high molecular weight (hmw) PAHs = sum of concentrations of twelve 4-and more-ring PAH compounds: fluoranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluorantene, benzo[k]fluoranthene, benzo[e]pyrene, benzo[a]pyrene, perylene, dibenzathracene, indeno[1,2,3-cd]pyrene, and benzo[ahi]perylene.Total PAH = low molecular weight PAHs plus high molecular weigh PAHs (sum of 24 PAH compound concentrations).Several numerical indices were chosen for analysis and interpretation of the macroinfaunal data. Infaunal abundance is reported as the total number of individuals per station and the total number of individuals per square meter (= density). Taxa richness is reported as the number of taxa represented in a given site location. Taxa diversity, which is often related to the ecological stability and environmental "quality" of the benthos, was estimated by the Shannon-Weiner Index (Shannon and Weaver, 1949).In order to quantify and compare the equitability in the fauna to the taxa diversity for a given area, Pielou's Evenness Index J' (Pielou, 1966) was calculated as J' = H'/lnS, where lnS = H'max, or the maximum possible diversity, when all taxa are represented by the same number of individuals; thus, J' = H' /H' max.
