The northern tip of Alexander Island - stock photo

The northern tip of Alexander Island, near the western base of the Antarctic Peninsula, illustrates one of the processes through which glaciers can contribute to sea level rise: iceberg production. In this image, several large icebergs have calved from Hampton Glacier. Near the glacier, the icebergs appear to be partially held in place by a mŽlange of ice that may include tiny iceberg fragments and frozen sea water. Farther out in Shokalsky Bay, the icebergs are floating more freely. Eventually, the bergs will drift northward to warmer waters, where they will melt.
