Sedimentary deposits from Greenland suggest a near-complete deglaciation of south Greenland, and a subsequent sea level rise of 4.5 to 6  metres of sea-level-equivalent volume during MIS 11, around 410,000 to 400,000  years ago.
The sedimentary material from Greenland's ice sheet suggests that almost all of south Greenland was melted around 410,000 to 400,000 years ago, resulting in a significant sea level increase of 4.5 to 6 meters during the MIS 11 epoch.
