Using AI to track icebergs

Researchers are using a new AI tool to detect icebergs in the Southern Ocean. This is the first step in being able to track the complete life cycle of most icebergs across Antarctica from satellite data. The study, "Unsupervised ...

Melting ice, falling snow: Sea ice declines enhance snowfall over West Antarctica

As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn ...
