Carbon storage potential of arctic seafloor sediments in Greenland

The seafloor stores large quantities of carbon and this is thought to increase with increasing climate change in the Arctic. However, we don’t fully understand the biotic and abiotic drivers of these stores. E.g. what causes carbon to be remineralised quickly or contributes to it being stored for decades to centuries. This project will collect sediment cores as part of a cruise to NE Greenland in August 2026, where we will collect sediment along fjord to shelf transects. Carbon remineralization potential will be assessed on board, by measuring oxygen penetration and respiration and back in the laboratory by measuring carbon content. This can be related to different environmental and biological variables collected as part of the cruise. MSc students will have the opportunity to participate in this research cruise alongside an international, interdisciplinary team.

Starting time: August 2026
