Antarctic iceberg larger than New York City breaks off ice shelf

R&I – FS

An iceberg larger than New York City has broken off an ice shelf in Antarctica, scientists say.

The 490-square mile glacier broke off the Brunt Ice Shelf, where the British Antarctic Survey’s Halley Research Station is located, the research organization announced. New York City is approximately 302 square miles.

Glaciologists have been expecting a large calving event for at least a decade, according to BAS. The first indication that the glacier would break off was in November, when a new chasm named the North Rift — the third major crack to become active in the ice shelf in the last 10 years — headed toward another chasm about 20 miles away.
