"A baseline inventory of water chemistry, sediment and biological conditions was undertaken by the Environmental Protection Service on the Beaufort Sea coast of the Yukon in August 1982. Investigations were conducted in two areas of potential development with samples being collected from lake, lagoon and nearshore marine habitats. The nearshore marine stations were predominated by the Arctic water mass with localized mixing occurring. Sediment metal levels and oils and grease levels were found to be typical of other Beaufort Sea sediments. Twenty three species of benthic invertebrates were identified. Four species not previously recognized in other Beaufort Sea literature were identified in the Stokes Point nearshore marine samples. The lagoons have brackish water characteristics reflecting recent closure and separation from marine water. King Point lagoon exhibits lower salinity and conductivity than Stokes Point lagoon. One station at Stokes Point lagoon showed excessively high oils and grease levels. Water chemistry data from the freshwater lake sample indicated low nitrite, nitrate levels. Tissue samples were obtained from two fish species and one isopod species and analyzed for extractable metals"--Abstract, page i. Issued also in print format.
