Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ice in steep decline.
Since 2015, Antarctica has lost sea ice equal to the size of Greenland—the largest environmental shift seen anywhere on Earth in the last decades. The Southern Ocean is also getting saltier, and this unexpected change is making the problem worse.
For decades, the ocean’s surface freshened (becoming less salty), helping sea ice grow. Now, scientists say that trend has sharply reversed.
Learning “universal representations” of life’s fundamental unit
When volcanoes are preparing to erupt, scientists rely on typical signs to warn people living nearby: deformation of the ground and earthquakes, caused by underground chambers filling up with magma and volcanic gas. But some volcanoes, called “stealthy” volcanoes, don’t give obvious warning signs. Now scientists studying Veniaminof, Alaska, have developed a model which could explain and predict stealthy eruptions.
