Alaska Monitoring and Assessment Program 2006-2007 Aleutian Survey

In 2006 and 2007, the Alaska Department of Environmental Conservation Alaska Monitoring and Assessment Program (AKMAP) and the University of Alaska Fairbanks School of Fisheries and Ocean Sciences, surveyed the Aleutian Islands. This report applies the index and ranking scheme, with some modifications, as used by the U.S. Environmental Protection Agency National Aquatic Resource Survey National Coastal Assessment 4 to evaluate environmental condition.

Overall condition of Aleutian Islands coastal near shore waters (6 to 20 meter depth) is rated good, with an overall condition score of 5.0. This is based on the water quality, costal habitat, and benthic habitat indices rating of good, with a fish tissue rating of fair. Sediment quality index was not evaluated as hard and soft bottom types were encountered and no index was established for mixed habitats. This environmental data was collected from 51 stations over 2 summers. Some rankings are based on fewer stations due to inability to collect all samples at every station or data/sample loss. A discussion of the indices and ranking method is detailed in the Condition Summary. As this is an initial AKMAP coastal survey no trends can be inferred, but this underscores the importance of continuing these surveys at future times to assess environmental change and trends in this important ecosystem.
