Coralline Algae Archive Fjord Surface Water Temperatures in Southwest Greenland
peer reviewed One of the most dramatic signs of ongoing global change is the mass loss of the Greenland Ice Sheet and the resulting rise in sea level, whereby most of the recent ice sheet mass loss can be attributed to an increase in meltwater runoff. The retreat and thinning of Greenland glaciers h...
