Larsen Ice Shelf: Environment for UPSC Exams

Larsen Ice Shelf: Environment for UPSC Exams

Larsen C:

  • The Larsen Ice Shelf is a long, fringing ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula.
  • It is named for Captain Carl Anton Larsen, the master of the Norwegian whaling vessel Jason, who sailed along the ice front in 1893.
  • The Larsen Ice Shelf is a series of shelves that occupy distinct embayments along the coast from north to south, the segments are called Larsen A (the smallest), Larsen B, and Larsen C (the largest) by researchers.
  • Further south, Larsen D and the much smaller Larsen E, F and G are also named.
  • The breakup of the ice shelf since the mid-1990s has been widely reported, with the collapse of Larsen A in 1995 and Larsen B in 2002 being particularly dramatic.
  • Larsen C has developed a rift 175 kilometres long and half-a-kilometre wide. A chunk of the shelf is poised to break off soon. When that happens, the ‘chunk’ will be an iceberg over 5,000 sq. km across and 350m high – more than four times the height of Delhi’s Qutub Minar and over an area one-and-a-half times the size of Goa.
  • If the glaciers held in check by Larsen C spilt into the Antarctic Ocean, it would lift the global water mark by about 10 cm, the researchers said.
  • Larsen C is the fourth largest ice shelf in Antarctica, with an area of about 50,000 km2.
