Dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSP) in Northern Baffin Bay during the 2014 ArcticNet/Netcare Campaign M. Lizotte, M. Levasseur, V. Galindo, M. Gourdal, M. Gosselin, M. Blais, and J. Charrette

Short summary
This study brings further support to the premise that the prevalence of younger and thinner icescapes over older and thicker ones in the Canadian High Arctic favors the early development of under-ice microorganisms as well as their production of the climate-relevant gas dimethylsulfide (DMS). Given the rapid rate of climate-driven changes in Arctic sea ice, our results suggest implications for the timing and magnitude of DMS pulses in the Arctic, with ramifications for climate forecasting.
