Ice Age Map Turns Deep Time into a Moving Coastline

Field notes

The atlas combines a date-controlled map with layers for ice sheets, exposed land, and modern coastlines. A click can return modeled grounded-ice thickness, while a sea-level readout places each view relative to the present; the homepage shows the Last Glacial Maximum at 21,000 years ago and an estimated 128-metre lower sea level. Supporting guides explain PaleoMIST, simplified coastlines, and named regions including Doggerland, Beringia, the Sunda Shelf, and Sahul.
