A tiny robot explorer traversed the vast, frigid waters of Antarctica—even diving under the ice at one point. After miraculously surviving all that, the robot brought back souvenirs for scientists. In 2020, researchers with CSIRO, Australia’s national science agency, deployed an Argo float—a free-floating, robotic instrument collecting ocean data—near Totten Glacier in East Antarctica. To […]
Scientists Uncover Surprising Link Between Tides and Earth’s Biggest Icebergs
In 2021, researchers in Antarctica noticed giant cracks developing on the Brunt Ice Shelf, an enormous stretch of ice on the continent’s northwestern corner. Two years later, the fracture grew so large that a gigantic iceberg almost twice the size of New York City broke free in a process called calving, sending scientists scrambling to […]
