ESA’s Copernicus Sentinel-1 captured a 29-square-mile (76-square-kilometer) section of Petermann Glacier’s floating ice tongue breaking away on Aug. 4, 2026—the Arctic’s largest ice-calving event since 2012—highlighting ongoing Greenland ice loss linked to warming oceans and climate change. Scientists say such observations help track glacier dynamics and their implications for sea-level rise and polar environments.
NASA's Earth Observatory showcases an ISS image of Tyndall Glacier in southern Chile, part of the Southern Patagonian Icefield, with icebergs drifting on Lago Geikie after recent calving. The glacier has shrunk since the Little Ice Age; Lago Geikie formed around 1940 as the ice retreated. Tyndall has lost about 2.2 km of length since Nov 2022 due to thinning and multiple calving events, including a major one in 2023. In May 2026 the front stood roughly 30–40 m above the lake, and scientists expect more iceberg production this fall as crevasses persist. Astronaut photography enables monitoring of remote glaciers like Tyndall and helps track ongoing climate-related changes.
The loudest underwater sound ever recorded, known as the 'bloop,' originated from the remote Point Nemo in the Southern Pacific Ocean and is believed to be caused by ice calving from Antarctic glaciers, highlighting the powerful natural forces beneath the ocean's surface.
In the remote Point Nemo in the Pacific Ocean, scientists detected a mysterious ultra-low-frequency sound in 1997, speculated to be from a giant underwater creature. However, NOAA Oceanographer Chris Fox suggested that the sound, known as the "bloop," was likely caused by ice calving off the coast of Antarctica. Similar sounds have been detected before and were attributed to icequakes generated by large icebergs cracking and fracturing, rather than unknown marine animals.
