Trident Biological Surveys: SUBASE Bangor (July 1977 and June 1978) and Indian Island Annex (January, May 1974 and June 1978). Supplement 2.
Abstract
In July 1977 and June 1978, biological surveys of the Trident Submarine Support Facility, SUBASE Bangor, Washington were conducted. The primary objective was to collect selected biological data for an assessment of the marine environmental conditions during a period of facilities construction. In January and May 1974 and June 1978, a series of biological surveys were conducted at Indian Island Annex, Washington. The objective of the first two surveys was to collect seasonal biological baseline data from which the impact of proposed pier construction could be predicted. The third survey was designed to collect biological data for monitoring environmental conditions during on-going pier construction. The major effort of these surveys was directed towards quantifying the abundance and distribution of commercially/recreationally important species of marine fishes and molluscs. Other biotic components of the ecosystem were surveyed according to their relative abundance and/or importance in the food web of other species. The general conclusion supported by the data collected from a total of eight surveys is that the marine life along the SUBASE shoreline appears to be unchanged by Trident construction. Any and all biotic fluctuations appear to be natural and are in synchronization with those observed at the off-base control stations. There have been no rare or endangered species or critical marine habitats affected by construction activities. Adverse impact has been limited to the biota physically disrupted by the mechanical process of pier construction.
