According to the Geological Survey of Norway.....
Astrid Lyså says that such old beach formations require that the sea all the way to the North Pole was periodically ice free for a long time.
Recent mapping of a number of raised beach ridges on the north coast of Greenland suggests that the ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago. The Arctic Ocean may have been periodically ice free.
”The beach ridges which we have had dated to about 6000-7000 years ago were shaped by wave activity,” says Astrid Lyså. They are located at the mouth of Independence Fjord in North Greenland, on an open, flat plain facing directly onto the Arctic Ocean. Today, drift ice forms a continuous cover from the land here.Astrid Lyså says that such old beach formations require that the sea all the way to the North Pole was periodically ice free for a long time.
Wonder if ABC Science will provide any coverage.
