IMIS - Marine Onderzoeksgroepen

The main objective is to describe and compare the biodiversity, using a variety of different diversity indices, in different locations of the Canadian Arctic in relation to environmental variables (e.g. substrate type, temperature, salinity, oxygen concentration, primary productivity, current speed, bottom topography). The surveys were done during the ArcticNet cruises since 2007 and were conducted each year onboard the CCGS Amundsen. A box core and an Agassiz trawl were deployed to collect macrobenthic fauna (endo and epifauna). Catches are completely sorted, weighted and identified to the lowest taxonomic level possible. The OBIS collection makes accessible a subset of the survey results. The current OBIS version includes presence information only. Abundance and biomass information may be released in a future version.
