In early 2009, the Nosed Iceberg began to drift northward, eventually coming into contact with the Larsen B ice shelf. This contact caused the iceberg to break into two pieces. The larger of the two pieces continued to drift northward, eventually reaching the Weddell Sea. The smaller piece remained in the area of the Larsen B ice shelf.
In early 2010, the larger piece of the Nosed Iceberg collided with the Larsen A ice shelf. This collision caused the Larsen A ice shelf to collapse. The collapse of the Larsen A ice shelf was the largest recorded collapse of an ice shelf in history.
The Nosed Iceberg has since melted away.
