<!--!introduction!--> Terminal glaciers of the Greenland Ice Sheet are bordered by hundreds of fjords and other marine areas. At the terminus of a marine-terminating glacier, a large amount of freshwater and suspended sediment (SS) is injected into the fjord by subglacial discharge.

This process can increase biological production in the surface layer during the summer melt season.
