History

The past. This small plate is all deep sea, 931 to 5,302 metres down, so the ice age gave it no new land and no ice: the sea stood more than 100 metres lower, and the winter sea ice stopped about 2,700 kilometres to the south. At the ice age peak the surface water here was about 3.5 to 4 degrees colder than today, and it warmed between about 16,800 and 11,600 years ago.

5.6 million years ago: This microplate began to form inside a long transform fault on the East Pacific Rise.
