August 2017 91 I n f o r m a t i o n R e q u e s t # 6 0 2 Big Ice Back in November of 2016 (photo), NASA's IceBridge Mission scientists measured the Larsen C Ice Shelf fracture in west Antarctica to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. Scientists have been monitoring the massive crack in the ice shelf for more than a decade. On July 12, 2017 it was reported the crack had finally cleaved from the ice shelf and is now a 5,800-square kilometer iceberg. It's about the size of Delaware. This is a big berg, but it's far from the largest. In 2000, the Ross Ice Shelf produced a berg twice the size of this one. Remnants of that berg passed by New Zealand in 2006. In 1956, prior to satellite observance over Antarctica, the U.S. Navy reported a berg estimated at 32,000 sq km, 5-times the size of the new Larson C berg, or about the size of Belgium. Still, if spread out, it's estimated the new berg would entirely cover the U.S. in 4.6" of ice. I n f o r m a t i o n R e q u e s t # 5 4 7
