Credit: NASA/James YungelSatellite radar data reveals substantial seawater intrusion below Antarcticas Thwaites Glacier, triggering ice to rise and fall.Using high-resolution satellite radar information, a team of glaciologists led by scientists at the University of California, Irvine uncovered evidence of the invasion of warm, high-pressure seawater lots of kilometers underneath the grounded ice of West Antarcticas Thwaites Glacier. In this research study, we reveal that the limitation of tidal flexing varies by kilometers over the tidal cycle, suggesting that pressurized seawater is able to intrude underneath grounded ice over kilometers and set vigorous heat exchange with the glacier base.”Rignot said the task helped him and his colleagues establish a much better understanding of the habits of seawater on the undersides of Thwaites Glacier.”Rignot said that he hopes and anticipates the results of this job to spur more research on the conditions beneath Antarctic glaciers, exhibitions including autonomous robots, and more satellite observations.”Reference: “Widespread seawater intrusions below the grounded ice of Thwaites Glacier, West Antarctica” by Eric Rignot, Enrico Ciracì, Bernd Scheuchl, Valentyn Tolpekin, Michael Wollersheim and Christine Dow, 20 May 2024, Proceedings of the National Academy of Sciences.DOI: 10.1073/ pnas.2404766121 Rignot, Dow, and Wollershiem were signed up with in this job by Enrico Ciraci, UC Irvine assistant professional in Earth system science and NASA postdoctoral fellow; Bernd Scheuchl, UC Irvine researcher in Earth system science; and ICEYEs Valentyn Tolpekin.
