Arctic Cod Pilot Genetics and Toxicity Study (AK-11a)
A greater understanding of the keystone species Arctic cod is necessary to fully assess the potential effects of offshore development in arctic waters.Conduct mitochondrial DNA profiles of Chukchi and Beaufort Sea Arctic cod samples presently held by John Nelson at the BC Canada DFO lab. Provide protocols and sampling supplies for field collection of central Beaufort Sea Arctic cod genetic samples in August 2011. Develop recommendations for a circumpolar effort to evaluate whether all or a portion of Arctic cod are ice dependent. In 2012, conduct mitochondrial DNA on Arctic cod samples collected in the BOEMRE 2011 central Beaufort Sea Marine Fish field survey. Final report to include recommended future directions for Arctic cod genetic research. Conduct a feasibility analysis for an Arctic cod and zooplankton toxicity study project design based on the results of the JIP study of toxicity to Arctic species at surface pressures. Review the results of the JIP study of toxicity to Arctic species at surface pressures, Arctic Oil Dispersant Toxicity Study. Provide recommendations for design and implementation of controlled laboratory studies to test the toxicity effects of gas/oil/dispersant mixtures on Arctic cod at critical lifestages, and at a range of temperatures and depths (pressures) typical of the U.S. Arctic OCS. Search for and review facilities capable of conducting toxicity tests simulating a minimum of 50 meter depths. Provide a range of recommended options and budgets to assess the effects on Arctic cod (and perhaps other species) of accidental subsurface release of gas/oil/dispersant mixtures at low temperatures and at pressures and oceanographic conditions typical of the U.S. Arctic OCS.
