Ocean circulation on exoplanets

Using computer models of ocean circulation on exoplanets, researchers report that if the oceans of exoplanets have sufficiently different average salinities from that of Earth, exoplanet oceans could circulate in the opposite direction to that of Earth’s oceans, with warm water sinking into the deep ocean in the tropics, warming the polar regions and potentially extending the exoplanet’s range of habitability. - See at PNAS.org
