Life exists everywhere you look. Even on glacier ice, home to inch-long worms, snow fleas, bacteria and algae. When gathered by the millions on the ice, algae cells can help make the water they need to survive. Alaska scientists recently studied this living agent of glacier melt. “If you went to a place on a […]
Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt. The research, led by chemistry professor William R. Simpson, is concerned with the Arctic’s reactive bromine season, which is the period of […]
Earlier this year Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic’s oldest and thickest sea ice. Operation IceBridge, NASA’s airborne survey of polar ice, launched a […]
Arctic sea ice in recent decades has declined even faster than predicted by most models of climate change. Many scientists have suspected that the trend now underway is a combination of global warming and natural climate variability. A new study finds that a substantial chunk of summer sea ice loss in recent decades was due […]
