A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.
A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.
Most recently, data from the seals — which routinely dive to depths of 1,000 to 2,000 feet — showed that water melting off the Antarctic ice sheet is causing the surrounding seas to become less salty, disrupting a conveyor belt-like system that transfers heat and nutrients around the globe.
