New Antarctic iceberg bigger than Delaware

The C-19 iceberg measures 124 miles long by 20 miles wide.

SUITLAND, Maryland (CNN) -- Satellite images have detected another in a series of massive icebergs calving off the frozen continent of Antarctica, the latest one bigger than the entire state of Delaware.

Dubbed iceberg C-19, the massive, rectangular ice block measures roughly 124 by 20 miles (198 by 32 kilometers), or 2,480 square miles (6,336 square kilometers) in surface area. While not quite the biggest iceberg to break away from Antarctica in recent years, C-19 is about 20 percent larger in area than the state of Delaware.

Last week, another new berg broke free. It was dubbed C-18, and measured roughly 47 by 4.6 miles (75 by 7 kilometers), or just less than 10 times the area of Manhattan.

C-18 and C-19 are adjacent to each other on the edge of the Ross Ice Shelf, a massive expanse of ice extending out from the continent in the portion of Antarctica that is nearest to New Zealand. National Oceanic and Atmospheric Administration monitoring of satellite images from the U.S. Defense Meteorological Satellite Program detected the new bergs.

In recent years, a series of increasingly larger icebergs breaking free from the continent have raised concerns that temperatures are on a steady warming trend in the Antarctic region. Such a trend, which many scientists believe may be an early sign of global warming, could have implications for climate changes over much of the planet's surface.

Others have raised concerns that these massive icebergs -- some over 4,000 square miles (10,000 square kilometers) -- could pose hazards to shipping as they drift northward and break up.

NOAA's National Ice Center monitors the locations of these traveling bergs, and in recent years its scientists have located icebergs within 1,000 miles of Cape Town, South Africa, and Christchurch, New Zealand.
