Passive water samplers (POCIS) were deployed in the STEER in February 2012. Developed by the US Geological Survey (USGS) as a tool to detect the presence of water soluble contaminants in the environment, POCIS samplers were deployed in the STEER at fi ve locations. In addition to the February 2012 deployment, the results from an earlier POCIS deployment in May 2010 in Turpentine Gut, a perennial freshwater stream which drains to the STEER, are also reported. A total of 26 stormwater contaminants were detected at least once during the February 2012 deployment in the STEER. Detections were high enough to estimate ambient water concentrations for nine contaminants using USGS sampling rate values. From the May 2010 deployment in Turpentine Gut, 31 stormwater contaminants were detected, and ambient water concentrations could be estimated for 17 compounds.

In addition, since benthic communities in much of Cook Inlet were previously poorly studied, other goals included describing the distribution of infaunal assemblages relative to environmental parameters and looking for range extensions or undescribed, non-indigenous, or cryptogenic species. A total of 22,203 animals (>1 mm) were collected at 44 stations (one station in lower Cook Inlet accounted for 60% of total organisms). Annelida comprised 78% of individuals with the polychaete Dipolydora quadrilobata accounting for 5952 individuals. Arthropoda dominated by the amphipods Ischyrocerus sp. and Photis sp. comprised about 12% of the total. Mollusca (mostly the bivalves Ennucula tenuis and Axinopsida serricata) accounted for 8% and miscellaneous and Echinodermata accounted for <1%. F...

This study characterized the spatial distribution of 16 major and trace metals in five strata in Kachemak Bay, as well as sediment total organic carbon content and grain size. Homer Harbor, a shallow harbor within the study area, contained elevated metal concentrations compared to the other strata. Outside the harbor, several metals, including Cr, Ni, Pb, and Zn, were significantly higher in the eastern strata than in the western portions of the bay. The opposite was true for a few other metals, such as Hg. However, most metal concentrations were below the National Oceanic and Atmospheric Administration's sediment quality guidelines for sediment toxicity to benthic communities.

The STEER Management Plan (published in 2011) identifi ed chemical contaminants and habitat loss as high or very high threats and called for a characterization of chemical contaminants as well as an assessment of their effects on natural resources. The baseline information contained in this report on chemical contaminants, toxicity and benthic infaunal community composition can be used to assess current conditions, as well as the efficacy of future restoration activities.

Following acclimation they were exposed to temperature shocks from 0 C (control) to 20 C above acclimation temperatures. Twenty-four-hour median lethal shock temperatures (LS50 values) were calculated by probit analysis. The temperature cycles used has no apparent effect on the thermal shock resistance of either
