:04:41. > :04:44.floating brunt ice shelf, just ten miles from the crack, British
:04:45. > :04:48.scientists are based at a station. The station is made up of big blue
:04:49. > :04:52.had is with a big red pod in the middle. They have made the decision
:04:53. > :04:56.to move their base because they don't know what will happen to the
:04:57. > :05:00.ice shelf in the next few months. Luckily, the pods are designed to
