Why did the Larsen ice shelf Collapse?
The collapse of the Larsen appears to have been due to a series of warm summers on the Antarctic Peninsula, which culminated with an exceptionally warm summer in 2002.
How big was the ice shelf that broke off?
about 460 square miles
An ice shelf larger than New York City has broken off eastern Antarctica, the first major shelf to collapse there in more than four decades of satellite observations. The Conger Ice Shelf, spanning about 460 square miles, shattered off the continent on March 15.
Has the Larsen C ice shelf disintegrated in the last 10000 years?
And what these investigations tell us is that Larsen C has maintained integrity throughout the last 10,000 years. It’s had a couple of phases of retreat in previous warm spells – roughly 9,000 and 4,000 years ago – but it’s never collapsed like its northern cousins.
How old is the oldest ice on earth?
So far, the oldest ice collected that way goes back 800,000 years. Now, several groups from around the world want to drill down to ice that’s even older, more than 1.5 million years old.
Where is iceberg a76 now?
the Weddell Sea
It now floats in the Weddell Sea.
What happened to the Larsen Ice Shelf in 2002?
Beginning on January 31, 2002, the Larsen B enters a period of rapid, dramatic collapse. Between January 31 and March 7, the shelf loses 2,717 square kilometers (1,049 square miles). Following this period of dramatic decline, the shelf continues shedding ice at a somewhat slower pace through mid-April.
When did Antarctica not have ice?
Antarctica hasn’t always been covered with ice – the continent lay over the south pole without freezing over for almost 100 million years. Then, about 34 million years ago, a dramatic shift in climate happened at the boundary between the Eocene and Oligocene epochs.
Did the ice age come before the dinosaurs?
Summary: About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth’s poles, and new species evolved with the new temperatures.
