Abstract: The distribution of dissolved organic carbon (DOC) in the Beaufort Sea was investigated in the summer of 2013, as part of the Beaufort Regional Environmental Assessment (BREA). DOC concentrations were measured at 36 stations (for a total of 320 samples analyzed) between August 1 and September 9, 2013 . Samples were collected using the rosette onboard the F/V Frosti. DOC concentrations were usually measured at the depths of 5, 20 and 70 m as well as the chlorophyll a maximum, the depth corresponding to 33.1% and in the bottom water. Leg 1 of the 2013 BREA Marine Fishes field campaign sampled 5 transects in Amundsen Gulf; Cape Parry (cpy), Darnley Bay (dar), Ulukhaktok (ulu), Cape Bathurst (cbh), Bennett Point (bpt). Station depths ranged from 40m to 500m. A transect along the 20m isobath, Escape (esc), was sampled near the Tuktoyaktuk peninsula. Leg 2 focused on the Western part of the Beaufort Sea; two transects from 2012 were re-sampled, Garry (gry) and Transboundary (tbs), and one transect in the US was sampled (a1). Leg 2 transects consisted of seven stations (40m, 75, 200, 350, 500, 750 and 1000m). Additionally a deep-water transect (dwt) consisting of 3 stations was sampled from 1200m-1500m depth. This data was collected to characterize the distribution of dissolved organic carbon (DOC) on the slope and in deep basins of the Beaufort Sea. This study contributes to our understanding of organic carbon pools and fish habitat in the Beaufort Sea.
