Why did the Larsen B ice shelf collapse?
A succession of unusually warm summers had increased the amount of melt water on the surface of the ice, which then wedged open crevasses in the ice, weakening and ultimately breaking up the shelf. The Larsen B ice is gone forever, but it left behind questions that scientists are now trying to answer in more detail.
When did most of the Larsen B ice shelf collapse?
31 January 2002
Where is the Larsen B ice sheet physically located here on Earth?
The Larsen Ice Shelf is a long, fringing ice shelf in the northwest part of the Weddell Sea, extending along the east coast of Antarctic Peninsula from Cape Longing to the area just southward of Hearst Island.

What is the largest ice shelf on Earth?
Ross Ice Shelf
How old is the oldest ice ever cored?
How big is a 68 iceberg?
With a surface area of 5,800 square kilometres, twice the size of Luxembourg, larger than Delaware and weighing one trillion tonnes, it is one of the largest recorded icebergs, the largest being B-15 which measured 11,000 square kilometres before breaking up.
How large was the largest iceberg ever recorded iceberg B 15?
around 295 kilometres
Where is a68 iceberg now 2019?
This movie shows A68’s progress from January 2018 to July 2019. It’s two years since the monster block of ice known as A68 broke free from Antarctica. Satellites show the world’s biggest berg has spun around in the waters of the Weddell Sea and is now moving north along the White Continent’s peninsula.
What are the implications of the Ross ice shelf melting?
Its magnitude, and the fact that thinning of the ice shelf will speed up the flow of Antarctica’s ice sheets into the ocean, mean that it carries significant sea level rise potential if it were to melt. Melting ice shelves like the Ross could cause seas to rise by several feet over the next few centuries.
Who is the Ross Ice Shelf named after?
Sir James Clark Ross
How large is Antarctica?
14.2 million km²
How big is the West Antarctic Ice Sheet?
General. It is estimated that the volume of the Antarctic ice sheet is about 25.4 million km3 (6.1 million cu mi), and the WAIS contains just under 10% of this, or 2.2 million km3 (530,000 cu mi).
What is the definition of ice shelf?
Ice shelves are permanent floating sheets of ice that connect to a landmass. … However, ice shelves can also form wherever ice flows from land into cold ocean waters, including some glaciers in the Northern Hemisphere.
