Many giant shelves of ice hanging off Antarctica into the Southern Ocean are now melting rapidly. But up to now, it has been a mystery why much of the resulting fresh water ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer: earth’s rotation is pushing meltwater sideways as it bleed off the ice, preventing it from reaching the surface. The finding has implications for how ocean circulation may affect the planet’s future climate. The research was published this week in the journal Nature.
