A stratified probabilistic sampling design was utilized to characterize the Delaware Bay system in terms of chemical contamination, sediment toxicity (Microtox, amphipod bioassay; sea urchin gamete bioassay; and P450 biomarker) and benthic infaunal community structure. The purpose was to define the extent and magnitude of toxicity and other biological effects associated with contaminants in the Delaware estuary system from the fall line to the mouth of the Bay. This file contains data measured in the Delaware Bay Estuary and adjacent waters during 1997. Samples were collected for water and sediment analyses. Specific objectives of the study were to: (1) Describe the levels and spatial distribution of contaminants in the Delaware Bay and adjacent waters; (2) Describe the incidence, severity and spatial extent of contamination, toxicity, and characteristics of the benthic infaunal community; (3) Describe the study results in relation to known or suspected sources of contamination; (4) Describe statistical relationships between levels of contaminants and adverse biological effects, and identify chemicals of concern in terms of regional environmental quality and adverse biological effects; (5) Compare environmental conditions within sub-areas of Delaware Bay and compare estimates of toxicity in Delaware Bay with those in other estuaries based on comparable data.The dataset objective is to report information about chemical residues in sediment, sediment toxicity, and benthic infauna characteristics of the system. The partners in the partners in the Delaware Bay Estuary Project were: (1) National Oceanographic and Atmospheric Administration (NOAA); (2) EPA; (3) Delaware River Basin Commission. The National Oceanographic and Atmospheric Administration (NOAA) was responsible for collection, final assembly and review of all data. completed NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian notPlanned Environmental Monitoring theme NOS Data Explorer Topic Category Microtox NCCOS Research Data Type > Field Observation NCCOS Research Priority > Long-term Monitoring NCCOS Research Priority > Stressors, Impacts, Mitigation, and Restoration (SIMR) NCCOS Research Topic > Bioeffects/Toxicity NCCOS Research Topic > Chemical Contaminants NCCOS Research Topic > Monitoring NSandT P450 human reporter gene system PAH PCB, organochlorines Site TBT amphipod analytes benthic bioassay butyltins chemical contaminants date estuary infauna inorganic latitude location longitude organic parameter pesticides polychlorinated biphenyls polynuclear aromatic hydrocarbons region sea urchin fertilization sediment state station toxicity theme Delaware Bay NCCOS Research Location > Geographic Area > Coastal Ocean NCCOS Research Location > Region > East Coast NCCOS Research Location > U.S. States and Territories > Delaware United States place DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Coordinates are expressed in units to the nearest 0.0001 decimal degrees. An acceptable tolerance goal for siting was that the sampling location be established within 0.2nm (+/- 120ft) of the given coordinates. In the event the vessel could not navigate to the site (i.e., too shallow) or the bottom type was not appropriate (i.e., rock or shellfish bed) then the first alternate site was substituted. In the event the first alternate could not be sampled then the second alternate site was sampled. Organic and Inorganic Contaminants - The measurement quality objectives of the Delaware Bay Project specify accuracy and precisionrequirements of 30% for organic analytes and 15% for inorganic analytes in sediment samples. Link to Quality Assurance Project Plan (Link to report - Contact NSandT Program Manager)Water column measurements - Water column monitoring instrumentation was calibrated based on manufacturers recommendations (YSI Corporation). Depth was recorded from the vessel fathometer.Benthic taxonomy-The minimum acceptable sorting efficiency was 95%. The minimum acceptable taxonomic efficiency was 95%. All chemical contaminant values have been rounded to three significant digits. To accommodate the wide range of values, all concentration values have been formatted to the thousandth unit (0.001). The actual precision is as listed below.Metals, variable ug/g Butlytins 0.01 ng Sn/gPAHs 0.1 ng/gPCBs 0.01 ng/gPesticides 0.01 ng/g Completeness Report Data are believed to be complete. Conceptual Consistency DATA QUALITY ASSURANCE PROCEDURES Site location - Handheld GPS units were compared daily with vessel GPS units. Organic and Inorganic Contaminants - QA procedures include blanks, spiked samples, and standard reference materials with each batch of samples. Any batch failing to meet the specifications described above would be reanalyzed or rejected.

Ten percent of samples were randomly selected and re-identified. A voucher collection composed of representative individuals of each species encountered in the project was accumulated and retained.

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 weigh (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. 1997-01-01T00:00:00 REFERENCES:Pielou, E.C. 1966.
