Posted on: August 28, 2015
If we asked you to pinpoint the Jakobshavn Glacier on a map, the majority of you would struggle to find it. It is in fact located in west Greenland and over recent weeks has been fascinating scientists. It is believed that at some point between the 13th and 19th August a large mass of ice broke away from the glacier. Measuring approximately 12.4 square kilometres in size, it would make the iceberg the largest ever witnessed to break away from the glacier.
It is estimated that Jakobshavn produces around 10 percent of the 30,000 to 40,000 icebergs calved annually in western Greenland. Once they break away they will slowly drift into the Davis Strait before heading out into the Arctic Ocean.
Types of Iceberg
Icebergs can generally be separated into two categories - tabular and non-tabular. Tabular icebergs are generally formed by ice that has broken away from a large ice shelf and can be identified as having steep sides and a flat top.
Irregular shaped icebergs come under the category of non-tabular and are sub-divided into categories including:Read full article
