The Nosed Iceberg: Antarctic Tabular Berg's Journey and Collapse

Initial Location

South of the Antarctic Peninsula tip. Dimensions: ~19 km × 11 km × 30 m thick. Named for its nose-like protrusion.

Drift and Breakup

• Early 2009: Drifted north, contacted Larsen B ice shelf, split in two.
• Larger piece: Reached Weddell Sea.
• Smaller piece: Remained near Larsen B.

Larsen A Collapse

Early 2010: Larger fragment collided with Larsen A ice shelf, triggering the largest recorded ice-shelf collapse.

Final Fate

The Nosed Iceberg has since melted completely.
