Thus, glacier retreat leads to an increase in spring runoff and a decline in summer runoff. (nichols.edu)
Unlike non-glacier runoff, glacier runoff correlates better with temperature than precipitation, due to the dominant role of glacier melt compared to precipitation in summer runoff from glacierized basins. (nichols.edu)
As glaciers expanded, spring and summer runoff poured nutrients into the coastal ocean, fueling explosive growth in krill and small animals the whales consumed, they speculate. (sciencemag.org)
