The Bering Strait has been the subject of the scientific theory that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels – a result of glaciers locking up vast amounts of water – exposed a wide stretch of the sea floor, [1] both at the present strait and in the shallow sea north and ...
Beringia sea levels (blues) and land elevations (browns) measured in metres from 21,000 years ago to present. Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula.

During the glacial epoch this bridge was a migration route for people, animals, and plants whenever ocean levels fell enough to expose the land bridge. [5] Archeologists disagree [ 6 ] whether it was across this Bering Land Bridge , also called Beringia , that humans first migrated from Asia to populate the Americas, [ 5 ] [ 7 ] or whether it ...
Dating the initial coastal migration is challenging because of the flooding of early settlement sites by the rise of the eustatic sea level accompanying deglaciation. Dates for sites such as ones at Ground Hog Bay in SE Alaska (10.2 ka) and Namu, about 800 km south of Ground Hog Bay near modern Bella Coola (9.7 ka) thus represent early mainland settlement above the present-day sea level after ...
Floating Coast: An Environmental History of the Bering Strait is a 2019 book by Brown University historian Bathsheba Demuth, published by W. W. Norton & Company. [1] The book examines environmental and social change in the Beringia region surrounding the Bering Strait from the mid-nineteenth to the late-twentieth centuries, focusing on the pursuits of American and Russian interests and their ...
[4] [5] It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. The Bering Sea is named after Vitus Bering , a Danish -born Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean .
Scientists mapped the flow of water through every single river on the planet, every day over the past 35 years, using a combination of satellite data and computer modeling. What they found shocked ...
