Newly discovered deep seabed channels beneath the Thwaites Glacier in West Antarctica may be pathways for warm ocean water to melt the undersides of the ice, and contribute to sea-level rise say scientists.

New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica, located just south of the former Larsen B shelf—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

One of the largest icebergs ever, roughly the size of Delaware just broke off Antarctica according to scientists who have been observing the area for years. While it’s not unusual for ice shelves to calve, many in the climate community fear that the breaking of Larsen C may be a signal of other events to come

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.

A metal tube packed with scientific instruments parachuted into the ice-cold waters of Antarctica’s Ross Sea on Tuesday, marking a new frontier in polar research. This ALAMO float and five others being deployed over the coming weeks are the first explorers of their kind to begin profiling the water adjacent to Antarctica’s Ross Ice Shelf and sending back data in real time. Their mission: find vulnerabilities where warmer (but still near freezing) water from the deep ocean may be seeping in under the ice shelf and melting it from below. That information, paired with aerial surveys currently mapping the ice shelf and the sea floor beneath it, will help scientists assess the stability of the Ross Ice Shelf as they seek to understand how quickly Antarctica will lose ice in a warming world and what that will mean for sea level rise globally.
