This geospatial animation shows sea level rising across the land bridge between Siberia and Alaska. During the last Glacial Maximum (~21,000 years ago), the Bering Land Bridge was a vast tundra plain connecting Asia and North America. At that time, the global sea level was 120 meters lower than it is today. Melting ice sheets and glaciers caused the sea level to rise and flood the land bridge. A QuickTime file of this animation can be viewed or downloaded for analysis, education and outreach. There are links to more information on the land bridge, Central Beringian marine climate and sea level, NPS field notes, paleoenvironmental atlas, PaleoGlacier atlas, and other data.
