In the deepest reaches of the Southern Ocean surrounding Antarctica lies the Antarctic Bottom Water, a mass of the coldest, densest lower layer of water in Earth’s oceans. Antarctic Bottom Water plays a key role in the circulation of seawater around the globe and therefore helps regulate Earth’s climate. However, its inaccessibility has made it difficult to monitor continuously over time.
