 "past": {"account": "The past. The Futuna plate is all deep sea, and it stayed open ocean through the ice age: even when the sea stood about 120 to 134 metres lower, none of its seabed came above the water, and the nearest sea ice lay some 5,000 kilometres to the south. The sea over it was a few degrees cooler at the ice age peak, about 1 to 4.5 degrees in different reconstructions, and warmed back between about 16,000 and 10,000 years ago. Its floor is still being made: Kulo Lasi, a young volcano found on the plate in 2010, is still active, with hot springs venting about 1,500 metres down in its crater.", "source": "Lambeck et al. 2014, PNAS 111:15296; Lhardy et al. 2021, Climate of the Past 17:1139; Paul et al. 2021, Climate of the Past 17:805; Osman et al. 2021, Nature 599:239; Fouquet et al. 2018, Ore Geology Reviews 99:314"},
