Sediment Assessment in Alaskan Waters to Target Restoration Efforts and Facilitate Management of Valuable Marine Resources
Scientists from the National Centers for Coastal Ocean Science collected sediments in August for contaminant assessment, ambient toxicity, and infaunal community description to characterize chemical contaminant impacts in intertidal and near-shore waters in Kachemak Bay. Using NOAA’s protocols, the sediments will be examined for over 120 chemical contaminants, multiple bioassays, and benthic community analysis. The study was conducted to address current impairment from past activities, and as a baseline assessment should Kachemak Bay be used as a port of refuge for damaged cargo ships (including oil tankers), and the planned enlargement of Homer Harbor. Results from the analysis will be incorporated into an integrated assessment with the Cook Inlet Regional Citizens Advisory Council covering all of Cook Inlet. Additional samples were collected in Port Graham Bay to assist local communities in assessing local environmental conditions.
