Sedimentation of organic material in Hudson Bay

Free-drifting, short-term particle interceptor traps were deployed from the CCGS Amundsen on eight occasions between 23 September and 16 October 2005. The traps were deployed at two or three depths below the euphotic zone (from 25 to 150 m) for 8 to 20 h. The sinking material was analyzed for particulate inorganic carbon, particulate and dissolved organic carbon, biogenic and lithogenic silica and chlorophyll a concentrations. Phytoplankton abundance and composition, fecal pellet abundance and biovolume and bacterial abundances were also assessed for the sinking material. Water column samples, from depths between 10 and 150 m, were collected to quantify fecal pellets. Lastly, phytoplankton from the deep chlorophyll maximum depth was collected and their sinking velocity determined using settling columns.

Purpose

This study was conducted to investigate spatial variability in the sedimentation of organic material in the Hudson Bay complex. The data collected will enhance our understanding of carbon cycling in the Hundson Bay Complex by providing the sinking export of organic material from the euphotic zone.
