38772 MB1_metadata Data Set Published / External 37215 NSandT Project Completed 2008-05 This study was based on the sediment quality triad (SQT) approach. The purpose was to define the extent and magnitude of contamination and biological effects associated with contaminants in the Massachusetts/Cape Cod Bays, Stellwagen Bank, and Boston Harbor. A stratified probabilistic sampling design was utilized to characterize the systems in terms of chemical contamination and benthic infaunal community structure. In addition, samples were taken in the vicinity of the new Boston sewage outfall in Massachusetts Bay and in Boston Harbor where the sewage outfall used to discharge. Toxicity bioassays were not done. A secondary objective was to coordinate with the NOAA NMFS to collect sediment and fish tissue samples at previously sampled Benthic Surveillance Program sites. This file contains sediment and water data measured in all areas sampled in 2004. Specific objectives of the study were to: 1. Describe the levels and spatial distribution of contaminants in the Massachusetts Bay area. 2. Describe the incidence, severity and spatial extent of contamination, 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; The dataset objective is to report information about chemical residues in sediment and benthic infauna characteristics of the systems. 994 PRINCIPAL INVESTIGATORS.

The "SITES" data file reports information regarding the planned sampling locations and the actual locations. The geographical information provided for a sampling site (the estuary stratum and site) is useful when interpreting the results of other data files.

MEASUREMENT QUALITY OBJECTIVES: SITE LOCATION - Sampling sites were located by GPS with a manufacturer reported position accuracy of better than 3 meters in DGPS mode. 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 Massachusetts Bay Project specify accuracy and precision requirements of 30% for organic analytes and 15% for inorganic analytes in sediment samples. WATER COLUMN MEASUREMENTS - Water column monitoring instrumentation was calibrated based on manufacturer's 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%. ACTUAL MEASUREMENT QUALITY - Water column measurements - Fields are arranged as follows: Measurement; Units; Expressed to Nearest; DO; mg/L; 0.1; Salinity; ppt; 0.01; Specific Conductance; mS/cm; 1; Depth; Meters; 0.5; Temperature; C;0.1; Data are believed to be complete 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/g; PAHs 0.1 ng/g; PCBs 0.01 ng/g; Pesticides 0.01 ng/g 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 presented in Section 9.1 would be reanalyzed or rejected. Water column measurements - Fields are arranged as follows: Indicator; QA sample type or measurement; Data generated for measurement quality DO; Water-saturated air calibration; Difference between probe value and saturation level. Salinity; Seawater standard; Difference between probe measurement and standard value. Specific Conductance; Seawater standard; Difference between probe measurement and standard value. Temperature; Thermometer; +/- 1C Benthic taxonomy- At a minimum, 10 percent of all samples were resorted and recounted on a regular basis. 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. 1 DATA ACQUISITION/FIELD SAMPLING Sediment sampling procedures are available for download (http://ccma.nos.noaa.gov/about/coast/nsandt/)DATA PREPARATION AND SAMPLING PROCESSING Fields are arranged as follows:Sample Type; Container; Field Holding; Lab Storage; Max Holding SEDIMENT Organic contaminants; I-Chem glass jars; Wet ice (4C); Freezer (-20C); 1 year Inorganic contaminants; I-Chem glass jars; Wet ice (4C); Freezer (-20C); 1 year Total organic Carbon; I-Chem glass jars; Wet ice (4C); Freezer (-20C); 1 year Grain size; Whirl paks; Wet ice (4C); Refrigerated (4C); 1 year BENTHOS Taxonomy; Plastic jars; 10% buffered formalin; Transfer to 70% ethanol; Indefinitely 2004-01-01T00:00:00 2 Chemicals with similar structural properties were summed and reported as "Totals" in addition to their individual measured concentrations. 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 Chlorinated benzenes = 1,2,4,5-Tetrachlorobenzene, 1,2,3,4-Tetrachlorobenzene, Pentachlorobenzene, Hexachlorobenzene and Pentachloroanisole Total Dieldrin = sum of concentrations of two compounds aldrin and dieldrin. Total cyclodines = sum of Heptachlor, Heptachlor Epoxide, Oxychlordane, Alpha Chlordane, Gamma Chlordane, Cis-Nonachlor, Trans-Nonachlor, Aldrin, Dieldrin, Endrin, Endosulfan II Total HCH = Alpha HCH, Beta HCH, Gamma HCH, Delta HCH 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. High Molecular Weight PAHs = Fluoranthene, Pyrene, Benz(a)anthracene, Chrysene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(e)pyrene, Benzo(a)pyrene, Perylene, Indeno(1,2,3-c,d)pyrene, Dibenzo(a,h)anthracene, Benzo(g,h,i)perylene High Molecular Weight Substituted PAHs = C1-Fluoranthenes/Pyrenes, C1-Chrysenes, C2-Chrysenes, C3-Chrysenes, C4-Chrysenes Low MW PAHs = Naphthalene, Biphenyl Acenaphthylene, Acenaphthene, Fluorene, Anthracene, Phenanthrene, Dibenzothiophene Low Molecular Weight Substituted PAHs = C1-Naphthalenes, C2-Naphthalenes, C3-Naphthalenes, C4-Naphthalenes, C1-Fluorenes, C2-Fluorenes, C3-Fluorenes, C1-Phenanthrenes/Anthracenes, C2-Phenanthrenes/Anthracenes, C3-Phenanthrenes/Anthracenes, C4-Phenanthrenes/Anthracenes, C1-Dibenzothiophenes, C2-Dibenzothiophenes, C3-Dibenzothiophenes 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. 3 Project Related References:Pielou, E.C. 1966.
