WebWhen sea ice forms it creates Antarctic Bottom Water (AABW), the heaviest, most dense water on the planet. This very cold, salty ‘Antarctic Bottom Water’ (AABW) is a by-product of sea ice formation, and helps drive the global ocean currents that keep the climate stable. AABW is very cold, salty water that forms under the sea ice. The Antarctic bottom water (AABW) is a type of water mass in the Southern Ocean surrounding Antarctica with temperatures ranging from −0.8 to 2 °C (35 °F) and salinities from 34.6 to 34.7 psu. As the densest water mass of the oceans, AABW is found to occupy the depth range below 4000 m of all ocean basins that have a connection to the Southern Ocean at that level. http://sam.ucsd.edu/ltalley/sio210/Atlantic_deep/index.html song rock and roll all night
