Short summary
We conducted snow observations on the coastal region in the northwestern Greenland Ice Sheet close to the North Water. The snowpack on the coastal region in the northwestern Greenland Ice Sheet contained aerosols originated from ocean biological activity and frost flowers in the North Water. The chemical substances in an ice core from the coastal region in the northwestern Greenland Ice Sheet could help explain past changes in ocean biological and sea ice conditions in the North Water.
