Tagged seals help find missing piece in global climate puzzle


Williams, GD, Tagged seals help find missing piece in global climate puzzle, Nature News, 2014, (February) pp. Online. ISSN 0028-0836 (2013) [Letter or Note in Journal]


By tracking the voyages of elephant seals off Antarctica, and with the help of satellite imaging and undersea sensors, researchers have discovered a long-elusive source for the deep-ocean streams of cold water that help to regulate the Earth's climate. Antarctic bottom water (AABW) is cold, highly saline water that forms near the shores of Antarctica. Being denser than typical seawater, it sinks to the depths and then moves north in sluggish currents that spread across the globe.
