50 years. The largest collapse was the Larsen A shelf in
1995 (3000 km
2
). This was matched in areal extent
again in 1999. Because this ice is already floating, it has
had no impact on sea level.
The second type of sea-ice is the annual pack-ice
that mainly forms within the seas of Japan and
Okhotsk, the Bering and Baltic Seas, the Gulf of St
Lawrence and along the south-east coast of Canada.
