Our long-term ice monitoring project is designed to alert us of any significant change in the ice. Ice calving, or iceberg or glacier calving, occurs when large pieces of ice break off of a glacier. “The frequency of relocation depends very much on how the ice behaves in the future. In 2017 BAS successfully relocated the station’s eight modules 23km (14 miles) upstream of a previously dormant ice chasm,” a spokesperson from the British Antarctic Survey told Newsweek. “The station is designed to be relocatable. ![]() ![]() The cracks and potential calving event are raising concerns about the Halley Research Station which has already had to be relocated because of instabilities along the ice shelf. Researchers are monitoring a giant crack in the center of the Brunt Ice. “If they merge upstream (south) of the McDonald Ice Rumples, then it’s possible that the ice shelf will be destabilized.” An iceberg about twice the size of New York City is expected to break off an ice shelf in Antarctica, NASA says. “The near-term future of Brunt Ice Shelf likely depends on where the existing rifts merge relative to the McDonald Ice Rumples,” said Joe MacGregor, a glaciologist at NASA’s Goddard Space Flight Center. The rumples are formed by the way ice flows over the rising bedrock in that area. The Halloween crack is growing eastward from the McDonald Ice Rumples, and where the second crack meets the Halloween crack near the rumples will determine how the iceberg calves from the shelf. What is unusual about this calving event is the way the second crack suddenly started speeding northward after remaining stable for 35 years. The Brunt Ice Shelf is a 400-foot-thick ice sheet where recently the Halley Research Station operated by the British Antarctic Survey (BAS) had to be relocated due to the Halloween crack. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. It does not store any personal data.When the two cracks meet, the massive iceberg will be released from the ice shelf. An iceberg the size of Chicago is about to split off the Antarctic ice shelf known as Larsen D, according to a glaciologist at the University of Swansea in England.
