Benthic Diversity across the Canadian Arctic

Data were mainly collected from the CCGS Amundsen (2015 to 2019) and from the William-Kennedy (2019).


An Agassiz trawl (1.5 m width × 0.7 m height, cod end of 0.5 cm mesh size) was towed on the seabed at a speed of 1.5-2 knots for 3 to 5 minutes to survey epibenthic species diversity, abundance, and biomass. Retrieved samples were washed with seawater in a sieve (2 mm mesh), and organisms were sorted and identified to the lowest taxonomical level possible. Each taxon was counted, and biomass was measured.


A box corer was deployed to quantitatively sample diversity, abundance, and biomass of endobenthic organisms (macrobenthos > 0.5 mm). After retrieval of the box corer, a subsample of 0.125 m2 area and 12-15 cm depth was collected and passed through a 0.5 mm mesh sieve to separate sediment from endofauna. Organisms were immediately preserved in a 4% buffered formaldehyde solution for further taxonomical identification in the laboratory.
