Phytoplankton and the MOSAiC expedition: organic sulfur cycling in the Arctic

Activiteit: Professional or public presentationProfessional


The Arctic is warming much faster than the rest of the world. Some organisms are able to thrive in the hostile polar environments, even though changing conditions are threatening their existence. Phytoplankton, in particular, play a key role in this ecosystem, being responsible for primary production and producing important compounds like dimethylsulfonio-propionate (DMSP).
As a postdoctoral researcher at the University of Groningen, I am currently working primarily on a project focused on the organic sulfur cycling in Arctic sea-ice and seawater. This project contributed to the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) field campaign ( We collected a record of the DMS(P) concentrations and distribution within the sea-ice and water column over the course of the yearlong expedition.
