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 investigate the icy chunk, which they named iceberg A-81. A team of researchers affiliated with the British Antarctic Survey sought to understand the forces driv
