Drifting Iceberg

May 2, 2013
On April 20, 2013 the Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard NASA’s Aqua satellite captured a true-color image of Iceberg C28A drifting in the remote waters of the Southern Ocean.

A relatively new iceberg, C28 was born in mid-February 2010 when massive iceberg B09B collided with the Mertz Glacier tongue on the George V Coast of East Antarctica. About 80% of the tongue broke off due to impact, and this fragment was called C28. At time of calving, the iceberg measured 78 km long and between 33 and 39 km wide. Over the years the iceberg has drifted from its initial location, and has broken into smaller pieces.

In this image, the large piece known as C28A, as well as several smaller icebergs surrounding it, can be easily distinguished from cloud by the bright white color. This is due to the highly reflective nature of ice.
