Observing the Unknown Winter Freshwater in Greenland Fjords
Studies have claimed that the volume of melt from the bed of the Greenland Ice Sheet is
too small to be of significance. We disagree.
We have carried out the first measurements of the meltwater as it flows into a Greenlandic fjord. The measurements were acquired during the winter where the water from the bed adds freshwater to the fjords.

Innovative measurements of ice-filled fjords during the winter. Inspite of challenging conditions, we retrieved multiple measurements of the water properties.
