During the Last Glacial Maximum (LGM), sea level dropped 120m. As a result, shallow area of the ocean became exposed (shown here in red)

POST-GLACIAL CHANGE• As the ice sheets melted away in the later stages of the last glacial and during the

early part of the Holocene (our current warm interglacial time), sea-level rose.• Sea-level reached a point close to the present level about 8,000 years ago.

There is also geologic evidence of times when sea level was higher than present

Above are two images of strandlines (raised beaches) in the Varanger Peninsula, on the extreme north coast of Norway -- on the shore of the Arctic Ocean / Barents Sea.
