Dissolved organic carbon distribution in the Canadian High Arctic, fall 2006

The distribution of dissolved organic carbon (DOC) in the water column of the Canadian High Arctic was investigated in 2006, as part of the ArcticNet program. Summer-fall DOC concentrations were measured at 27 stations between 4 September and 17 October 2006. 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.
