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.
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.
The next pictures focus on the famous Ross Ice Shelf. Note the size of the ice shelf compared to the people in the photo. The picture shows the Ross Ice Shelf, the largest in the world, at the Bay of Whales - the point where Amundsen staged his successful assault on the South Pole. 78 30 S Latitude 164 20W Longitude.
