What does this data set describe?

Title:
National Status and Trends, Benthic Surveillance Project Sites, 1984-1992, National Centers for Coastal Ocean Science
Abstract:
This data set reports information regarding the nominal sampling locations for the National Status and Trends Benthic Surveillance Project sites. One record is presented per site. Each record reports the five letter site acronym, site sequence number, general and specific location information, state abbreviation, state name, degree-minute-second coordinates, decimal degree coordinates, and species information, among other things. The actual site coordinate information is recorded at the time of sampling, if samples were taken at a location other than the nominal site center. The five letter acronym is based on both the general location information and more specific location information (e.g. SFSM is San Francisco-San Mateo Bridge). The file also contains sequence numbers that facilitate geographic manipulation of the data. Sites are numbered sequentially from the northern most site on the U.S. East coast (i.e. Penobscot Bay-Pickering Island) and continue counter-clockwise around the country.

Why was the data set created?

In response to concerns over environmental quality of the Nation's coastal and estuarine ecosystems, NOAA created the National Status and Trends (NSandT) Program in 1984. From 1984 through 1993, the Benthic SurveillanceProject monitored chemical concentrations in the livers (and for metabolites of PAH's in the bile) of bottom-dwelling fish and in sediments at the sites of fish capture. The Benthic Surveillance Project also measured the biological effects of contaminant exposure, primarily as prevalence's of toxicopathic liver diseases.

    National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), 198805, NOAA Technical Memorandum NOS OMA 40, "National Status and Trends Program for Marine Environmental Quality: Benthic Surveillance and Mussel Watch Projects Sampling Protocols".

    Type_of_Source_Media: document
    Source_Contribution: Benthic Surveillance Sampling Protocols.

  2. How were the data generated, processed, and modified?

    Date: Unknown (process 1 of 1)
    A National Benthic Surveillance Project site bears the name of the general coastal or estuarine region sampled, and is defined by the individual stations in that area where bottom sediments are obtained. In most cases, threestations comprise a site. Trawls for bottomfish are conducted as close to the sediment stations as possible.Sediment samples are obtained by a specially constructed box core device or a standard Smith-MacIntyre bottom grab. National Benthic Surveillance Project sediment samples are analyzed for selected organic compounds, trace elements, total organic carbon, moisture content, and particle size. NOAA compiled a field sampling manual to ensure uniformity for sediment and fish sample collection.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

    The same kind of field/site data have been supplied since the start of the Benthic Surveillance Project, in 1984. Original site coordinates were derived from Loran-C time conversions. When GPS was first available the signal wasintentionally degraded so earlier coordinate information, even if it resulted from GPS, is not as accurate as data would be today.Early sites information resulting from Loran-C was converted from time delay information to latitudes and longitudes. These earlier data may be suspect when sites were located close to large structures that could have interfered with accurate time delays. These concerns apply specifically to the first National Status and Trends sites document, NOAA Technical Memorandum NOS ORCA 70, National Status and Trends Program: Monitoring Site Descriptions (1984-1990) for the National Mussel Watch and Benthic Surveillance Projects.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Using site selection criteria similar to those used for the Mussel Watch Project, the NBSP monitored contaminant exposure and bioeffects at more than 120 sites nationwide. The National Benthic Surveillance Program existed from 1984 through 1992. This was a cooperative effort between NOS and the National Marine Fisheries Service's Northwest, Southeast, and Northeast Fisheries Science Centers.The Benthic Surveillance Project Sites dataset does not include information relating to the chemistry, quality assurance, or pathology data that is associated with each site.

  5. How consistent are the relationships among the observations, including topology?

    Field sample processing is minimal while laboratory sample processing is extensive. The same kind of field/site data have been supplied since the start of the Benthic Surveillance Project, in 1984.


How can someone get a copy of the data set?
