Description: A baseline environmental characterization of the inner Kachemak Bay, Alaska was conducted using standardized National Status and Trends Bioeffects Program methods, the sediment quality triad approach based on sediment chemistry, sediment toxicity, and benthic invertebrate community structure. Three sites near the village of Port Graham were also sampled for comparison. Concentrations of over 120 organic and metallic contaminants were analyzed. Ambient toxicity was assessed using two bioassays. A detailed benthic community condition assessment was performed. Habitat parameters (e.g. depth, salinity, temperature, dissolved oxygen, sediment grain size, and organic carbon content) that influence species and contaminant distribution were also measured at each sampling site. Methods and results are reported in Hartwell et al. 2009 , available for download as a pdf at https://repository.library.noaa.gov/view/noaa/2628 . Results are also summarized in a NOAA Special Report (Hartwell et al. 2011), available for download as a pdf at https://repository.library.noaa.gov/view/noaa/2582.
