For the homonymous article, see Ice Bridge. Natural ice bridge in Wilkins, Antarctica.
A natural ice bridge is a frozen expanse of seawater or freshwater that connects, like a bridge, the shores of a bay, river or lake. When it forms along the ocean coast, it is part of the fast ice. These ice can be seasonal or last several years, depending on the temperature regime.
These bridges allow an impossible animal and human migration in a milder period. Thus during the last ice age, around -9,000 BC. J-C., An ice bridge connected the island of Öland to Sweden which allowed the migration of the first populations on this island. Notes and edit the code
