00:00UK researchers just paid a visit to the world's largest iceberg.
00:04That berg is called A23A and the RRS Sir David Attenborough arrived at it on Friday.
00:09Their footage shows off A23A's immense size,
00:131,500 square miles, about five times the land area of New York City.
00:18The iceberg broke off from Antarctica's mainland in 1986.
00:22For many years it was anchored to the seafloor, but in 2023 it began moving into the Southern Ocean.
00:26You might expect this development to be related to climate change,
00:29but that's not necessarily the case.
00:31University of Colorado Boulder researcher Ted Scambos told NPR that while melting sea ice
00:36is a global concern, this sort of large iceberg movement is just the way Antarctica works.
00:41According to the BBC, the Attenborough's crew is studying carbon and nutrient cycles
00:45in polar regions and collected water samples in A23A's vicinity.
