Project discription: 

Impact of glacial melt water on coastal carbon cycling
We will conduct a multidisciplinary study of Greenland ice sheet-ocean interactions in Greenland fjords. Based on oceanographic surveys along ∼5 transects from the shelf towards main outlet glaciers in NW Greenland we will:

  • Identify near shore water mass characteristics and bathymetry to assess potential marine heat sources and circulation processes important for glacial melt
  • Identify impacts of glacial melt water on vertical mixing, light and nutrient conditions and subsequent rates of phytoplankton production. Focus on documenting if glacial fronts are areas of increased biological production. 
  • Determine surface pCO2 values and carbonate system dynamics including pH and aragonite saturation states to confirm if glacial fjords are sites of high uptake of atmospheric CO2.
  • Determine the importance of glacial derived carbon for pelagic and benthic carbon cycling
  • Describe long term Ice Sheet-Ocean dynamics using proxy records stored in marine sediments

Geographical area:

We will sample transects (approximately 20 stations along each transect) from the shelf towards each of the following outlet glaciers in NW Greenland:

  • Sermeq Kujalleq (Jakobshavn Isbræ), 69° N
  • The Uummannaq fjord system, 70° N
  • Kangilliup Sermia (Rink Isbræ), 71° N
