Dissolved organic carbon distribution in the Canadian Arctic, fall 2007

The distribution of dissolved organic carbon (DOC) in the water column of the Canadian Arctic was investigated in 2007, as part of the ArcticNet program. Summer-fall DOC concentrations were measured at 30 stations between 29 September and 3 November 2007. Samples were collected using the rosette onboard the CCGS Amundsen. Euphotic zone sampling depths corresponded to surface irradiances between 0.2 and 100% as well as the chlorophyll a maximum depth. Aphotic sampling depths ranged from 75 m to the bottom waters.
