Regional variability of megabenthic community structure across the Canadian Arctic

Benthic fauna were sampled at 78 stations between June and October from 2007 to 2011 onboard the Canadian research icebreaker CCGS Amundsen. Station depths ranged from 34 to 1024 m, all below the average ice scouring zone. All faunal samples were collected with an Agassiz trawl (effective opening of 1.5 m and a 40 mm net mesh size, with a 5 mm cod end liner) with average trawling time and speed of 5 min and 1.5 knots, respectively.

Purpose

The main objective was to assess the observed number of megabenthic taxa and predict the total number of taxa expected to occur in five geographical regions located within the Western and Eastern Canadian Arctic biogeographic units. From west to east these five regions are: Beaufort Sea, Amundsen Gulf, Western Archipelago, Eastern Archipelago, and Baffin Bay. These five geographical regions also correspond largely to annual discrete sampling segments (legs) of the CCGS Amundsen program. Consequently, the present results inform national programs, such as the Fisheries and Oceans Canada (DFO) conservation assessments, and the planning of future field campaigns aiming at increasing megabenthic species records in the Canadian Arctic. This study also increases our knowledge of the marine diversity on a pan-Arctic level and will serve as a benchmark against which changes in megabenthic diversity deriving from species range shifts or invasive species could be identified.
