A monstrous iceberg - nearly as large as New York's Long Island - has barrelled along the Antarctic coastline, coming to a stop at a well-known geographic feature of Antarctica, a floating tongue of ice hitched to the Ross Ice Shelf. The iceberg, known to scientists as C-16, is being monitored by satellite by scientists at the University of Wisconsin-Madison's Antarctic Meteorological Research Centre (AMRC).
Currently, it is cushioned by sea ice from colliding with a feature known as the Drygalski Ice Tongue, a spit of ice that protrudes 50 miles into the ocean. Scientists are unsure of how long the iceberg will stay moored next to the ice tongue, or what damage it may do. Should the tongue break loose from its hold on the Ross Ice Shelf, it could alter ocean currents along the Scott Coast of Antarctica and would change the region's climate, according to meteorologist George Weidner of UW-Madison's Department of Atmospheric and Oceanic Sciences.
