2019 MarineGreen cruise in Disko Bay, West Greenland
The aim of the 10-day cruise with R/V Sanna in Disko Bay (West Greenland) is to study the effects of suspended glacial sediments input on the chemical oceanography, marine pelagic productivity and community composition. The cruise contributes to the wider aims of an ongoing three-year project (MarineGreen) that investigates the utilization of Greenlandic glacial rock flour (GRF) in marine remediation applications. The focus is on quantifying processes where reactions with suspended glacially derived particles are the main drivers, and using the results to help predict the behaviour of rock flour in the wider ocean context. Simultaneously the results are relevant to processes at the base of the food web in the Greenland coastal waters, which are changing due to increases in meltwater fluxes and decreases in sea-ice. These factors can potentially have a major impact on the future of the Greenland fishing economy.
The cruise has 8 participating scientists from the University of Copenhagen, Greenland Institute of Natural Resources, and GEOMAR
