Onboard Large-Scale Isolation and Characterization of Three Reference DOM Materials from Siberian Arctic Shelf Marine Water.

ABSTRACT: The Siberian Arctic Shelf is undergoing major climate change in the Northern Hemisphere, heavily impacted by a massive release of dissolved organic matter (DOM) due to degradation of permafrost as a consequence of global warming. This work is devoted to the isolation of large quantities of DOM from the Kara Sea, the Laptev Sea, and the East Siberian Sea, located from west to east along the Siberian Arctic Shelf. The goal was to isolate Arctic marine water reference DOM materials, addressing the gap in the set of available reference DOM materials. Large volumes of marine water (500-700 L) were collected from the three target seas and processed using a large-scale solid-phase extraction (SPE) setup aboard the research vessel "Academic Mstislav Keldysh" to establish a detailed molecular chara
