Oceanographic data in support of benthic biodiversity surveys in Baffin Bay and Davis Strait, 2012: Fs97-16/201E-PDF

"Oceanographic and biochemical sampling was conducted in Baffin Bay and Davis Strait providing ecosystem data for surveys of Arctic marine benthic biodiversity. The benthic survey work was led by Fisheries and Oceans Canada in support of the Arctic Marine Biodiversity Monitoring Plan. CTD (Conductivity, Temperature, Depth) and auxiliary sensors were deployed between 16 September and 12 October 2012 at 24 stations ranging in depth from 200 to 1100 m. Eight of the stations were located across Davis Strait and the remaining stations were in Baffin Bay. For each station, vertical profile plots of CTD data are presented including temperature, salinity, transmissivity, fluorescence, dissolved oxygen, photosynthetically active radiation and pH. The CTD was deployed with a rosette for the collection of discrete water samples to measure inorganic nutrients throughout the water column. At select stations, chlorophyll a was also measured in the upper 100 m of the water column. Vertical profile plots are presented for the discrete water sampling of inorganic nutrients (NO3, NO2, PO4, Si(OH)4), and total and size fractioned chlorophyll a concentrations. The physical characteristics of the water column and productivity indicators (i.e. nutrients and chlorophyll a) presented are relevant for the management of ecosystems (e.g. VMEs and EBSAs) as well as shrimp and Greenland Halibut fisheries in the study area"--Abstract, p. v.
