Particulate organic matter along the Northern Sea Route

The comparative evaluation of the content of particulate organic carbon (POC) in surface seawater along the Northern Sea Route from Norway to the East Siberian Sea (the southern track) during the summer seasons of 2004–2011 was carried out based on the authors’ data. The content and distribution of organic component in particulate matter were estimated, as were the proportion of phytoplankton, detritus, and the mineral component in the composition of particulate matter.
