Abstract: The research will consist of collecting samples of pelagic and benthic invertebrates at ten sites across Baffin Bay as part of ArcticNet's 2013 Amundsen research expedition, taxonomically identify the organisms, and analyze 12 samples per site for petroleum hydrocarbons. At each site, three benthic species and three pelagic species will be analyzed in replicate. Samples will be analyzed for hydrocarbons in the laboratory after the expedition using a modified US EPA 8279 methodology. The purpose of this study is to establish baseline concentrations and chemical profiles of petroleum hydrocarbons (polycyclic aromatic hydrocarbons (PAHs) and alkanes) in entry level food web organisms across Baffin Bay. The overall objective of ths research is to assess any spatial variability in hydrocarbon concentrations and profiles in benthic/pelagic species, particularly between those samples collected at documented oil seep areas versus control sites and to determine the contributing sources of the hydrocarbons. Such data will enable the long-term monitoring of hydrocarbons with time and provide territorial capacity to assess quality of the marine environment and the wild marine food supply.
