Abstract: "The Benthic Surveillance Project monitors contaminant levels in surficial sediments, selected bottomfish, and fish stomach contents in nearshore waters of the United States. From 1984 through 1986, samples were collected from monitoring sites on an annual basis. Since 1987, sites have been monitored every other year, due to fiscal restraints. Collection activities take place in the Northeast between April and June, in the Southeast and Gulf of Mexico between August and October, and on the West Coast between May and July. The data base presently (as of summer 1992) contains six years of analytical data, from 1984 to 1989. As of 1992, sediment and fish tissue samples had been collected for 1991, and samples collected in 1990 were being analyzed for contaminants. Samples are collected and analyzed for contaminants by scientists from the National Marine Fisheries Service (NMFS). Samples from the Northeast and West Coasts are analyzed by the NMFS Environmental Conservation Division, Northwest Fisheries Center at Seattle, WA. The NMFS Beaufort Laboratory, Southeast Fisheries Center at Beaufort, NC, monitors Southeast coastal waters through the Gulf of Mexico to the Mexican border. Both laboratories participate in the NS&T Quality Assurance Project to ensure intercomparison of the data." From: http://gcmd.nasa.gov/records/GCMD_ORCA_CMBAD_NS_T_BSP.html
