History

The past. The Manus plate is young sea floor 1,800 to 2,900 metres deep, so when the ice age sea stood about 120 metres lower it stayed open water, and no ice ever reached it. The sea surface above it was about 3 degrees colder at the ice age peak, going by cores in the Bismarck and Solomon seas, and warmed back to within a degree of today between about 13,000 and 11,000 years ago. In these 30,000 years the plate has also turned about one and a half degrees, probably faster than any other plate.

780,000 years ago: A reorganization of the plate boundaries in the Manus Basin created this tiny plate.
