Sažetak
Surface-active organic substances (SAS) represent a large part of oceanic waters organic matter. Participation in hydrophobic and electrostatic reactions, both in bulk water and on all phase boundaries, makes them very reactive part of organic carbon. Their dynamic appeared to be much more sensitive to environmental changes as compared to general parameter as it is DOC. Furthermore, folic acid can play a significant role as indicator of the cycling of the trace constituents in coastal seawater and as such is marker of a certain biogeochemical processes. The first results on SAS and folic acid vertical and horizontal distribution in the northern polar region in the summer time period will be presented. The sampling was performed in the northern Barents Sea and on one station in the European Arctic Ocean. The Barents Sea is a very productive region contributing 45% of the arctic shelf production. Arctic itself play an important role in the global carbon cycle and climate change. The results are supported with environmental data (chl a, salinity and temperature). Results will be presented to understand OM origin, its new production and fate together with potential role for organic carbon sink
