Huge Block of Ice
Pictured above is an iceberg off the Antarctic Peninsula. The size of the iceberg appears to be similar to that of a cruise ship. Photographer: Commander Richard Behn, NOAA Corps.

Follow the Leader
Note the arches in the icebergs off the Antarctic Peninsula. The icebergs are slowly moving along the waters. Photographer: Commander Richard Behn, NOAA Corps.

Formation of an Iceberg
Icebergs form when they are broken off from a glacier or an ice shelf. Here is an example of an iceberg breaking from a glacier. More than a decade ago a large iceberg (over a thousand square miles in area, and a quarter of a mile thick) broke off an Antarctic glacier and drifted into the Southern Ocean. This true color Landsat 7 image shows relatively small icebergs "calving" off the edge of B10A. The new icebergs drifted into international shipping lanes, posing a threat.
Point of Separation
In this picture, two large icebergs, designated B-15A and C-16, are captured in this Multi-angle Imaging Spectroradiometer (MISR) nadir camera view of the Ross Ice Shelf and Ross Sea in Antarctica. B-15A is the largest chunk left of a bigger iceberg, known as B-15 that broke off the Ross Ice Shelf in March 2000. That initial frozen hunk was about the size of Jamaica. At 71 miles (115 kilometers) long, B-15A is the largest free-floating object in the world. The image was acquired on December 10, 2000, prior to when B-15A broke off from the Ross Ice Shelf.
