“For the past five months, NASA scientists have been tracking a rather large iceberg that separated from the front of Antarctica’s Pine Island Glacier. Measuring some 20 miles (33 km) long and 12 miles (20 km) wide, the so-called “ice island” has now drifted out to sea.
Called B31, the massive object came loose in early November 2013. NASA scientists have since tracked its journey using the Moderate Resolution Imaging Spectroradiometer (MODIS), an instrument on NASA’s Terra and Aqua satellites.”
