When released into seawater, DMSP is rapidly catabolised by bacteria via two enzymatic pathways: demethylation and cleavage6–8. The demethylation pathway converts a large fraction (50 to 90%) of dissolved DMSP to 3-methylmercaptopropionate (MMPA), which is subsequently incorporated into the ...

On the western side of the Arctic Ocean, the freshwater is accumulated in the anticyclonic Beaufort Gyre (BG in Figure 1). The BG is driven by the anticyclonic wind stress curl forced by a high-pressure system in the lower atmosphere [19,20]. Closer to the coast, we found the cyclonic...

We suggest that within the entire range of observed fluxes, the lowest rates (≤3 mg m−2 d−1) are associated with an initial degree of subsea permafrost thawing observed in the shallow- and mid-shelf outside the areas affected by faults, rivers, and pre-existing thermokarst (Figure ...
