Organic matter characterization and fate in the subarctic Norwegian fjords during late spring/summer period
The organic matter (OM) pool has been studied in two subarctic north Norwegian fjords, Balsfjord and Ullsfjord, in July 2001 and June 2003. Besides general OM parameters such as dissolved organic carbon (DOC), particulate organic carbon and nitrogen (POC and PON), the distribution of specific compou...
