These robots are a platform to bring science instruments to the hardest-to-reach locations on Earth," Paul Glick, a JPL Robotics engineer and principal investigator for the IceNode project, said in a summary posted on Thursday on NASA's website.
If melted completely, according to NASA, the loss of the continent's ice shelf would raise global sea levels by an estimated 200 feet (60 meters).
Satellite images have shown the outer 'calving' off into icebergs at a higher rate than nature can replenish shelf growth.
A JPL analysis published in 2022 found that thinning and crumbling away of Antarctica's ice shelf had reduced its mass by some 12 trillion tons since 1997, double previous estimates.
