Monitoring hydrocarbons and trace metals in Beaufort Sea sediments and organisms. Final report
As part of the Minerals Management Service's environmental studies of oil and gas exploration and production activities in the Alaskan Beaufort Sea, a study was conducted in 1989 to monitor the marine environment for inputs of chemicals related to drilling and exploration. The 1989 Beaufort Sea Monitoring Program (BSMP) was designed to monitor sediments and selected benthic organisms for trace metals and hydrocarbons so as to infer any changes that might have resulted from drilling and production activities. A series of 49 stations were sampled during the program. The study area extended from Cape Halkett on the western end of Harrison Bay to Griffin Point, east of Barter Island. The sampling design combined an area-wide approach in which stations were treated as replicates of 8 specific geographic regions, with an activity-specific approach, which focused on the potential establishment of metal or hydrocarbon concentration gradients with distance from the Endicott Production Field in Prudhoe Bay. The analytical program focused on the analysis of the fine-fraction of the sediment for a series of trace metals and elements and the analysis of a suite of saturated and aromatic hydrocarbons in the bulk sediment. The total organic carbon (TOB) content and the grain size distribution in the sediments were determined as well. Benthic bivalve molluscs, representative of several feeding types were collected from those stations for which data previously existed from the 1984-1986 BSMP, and were analyzed for metals and saturated and aromatic hydrocarbons. The benthic amphipods were collected, pooled by station or region, and analyzed as well.
