Elephant seals wearing head sensors and swimming deep beneath Antarctic ice have helped scientists better understand how the ocean's coldest, deepest waters are formed, providing vital clues to understanding its role in the world's climate.

said researchers at the Antarctic Climate Ecosystem CRC in Tasmania.
