How the Thawing of Antarctica Affects the Transport of Heat Throughout the Ocean
Dr. Drew Friedrichs will discuss how melting Antarctic ice shelves reveal how the trillions of tons of ice shelf meltwater produced each year interact with coastal ocean currents, with downstream effects felt globally.
The one-thousand-foot-thick ice shelves that fringe Antarctica help limit to global sea level rise by pinning back land ice and slowing its export into the Southern Ocean. However, some of these ice shelves are rapidly melting from below due to the encroachment of warm seawater. Over the past few years, TERC scientists and engineers have deployed the same instrumentation in use in Lake Tahoe to collect rare measurements of ocean water along the Antarctic coastline. These observations reveal how the trillions of tons of ice shelf meltwater produced each year interact with coastal ocean currents, with downstream effects felt globally. Our insights suggest that existing ocean models may incorrectly estimate how meltwater affects the mixing of heat from the sea surface to the deep ocean, a process critical to predicting the state of our planet in coming centuries.
