Abstract
The Baffin Island Oil Spill (BIOS) Project was carried out in nearshore shallow waters at Cape Hatt, northern Baffin Island. Observations and limited data on phytoplankton, zooplankton, fishes, birds and mammals at Cape Hatt and more detailed information on microheterotrophs indicate that the BIOS site is typical of the majority of eastern and central High Arctic coastal areas. Detailed baseline information on nearshore macrobenthos (infauna, epibenthos and macroalgae) is, in general, similar to that previously reported for other eastern and central arctic locations; comparisons were hindered by a scarcity of detailed studies elsewhere, differences in sampling methods and complexity in infaunal community structure. ... An evaluation of the sampling design and procedures used in this study (including efficiency of the diver-operated airlife sampler, the area, location and number of replicate samples collected; and bias, efficiency and consistency in laboratory analysis) indicated that representative samples of the nearshore macrobenthic communities were obtained. The study design and analysis of variance procedures used to analyze the data provided a rigorous framework within which oil effects were evaluated. Key words: Arctic, benthos, phytoplankton, bacteria, benthic sampling design, sediment, experimental oil releases, Baffin Island, baseline, microheterotroph
