WASHINGTON — Glaciers that detach from the seafloor and begin floating create larger icebergs than glaciers that stay on the sea floor, researchers have found. Floating glaciers also produce icebergs more erratically.
These new observations may help researchers better understand and predict iceberg production from glaciers and ice sheets, improving estimates of sea-level rise due to climate change.
ANN ARBOR, Mich.—University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year’s Gulf of Mexico “dead zone” is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery.
