A massive crack in a huge sheet of Antarctic ice discovered in mid-October last year is steadily growing, as seen in recently released satellite images.
The fissure in the Pine Island Glacier ice shelf marks the beginning stages of the birth of a 350-square-mile (900 square kilometers) iceberg, part of a natural process known as calving.
The image was snapped on Nov. 13, 2011, when the rift was roughly 19 miles (30 km) long, 260 feet (80 meters) wide for most of its length, and 195 feet (60 m) deep. When researchers first spotted the crack in mid-October, it was roughly 18 miles (28 km) long.
