A short 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.
