Sea-Level Changes during the Last 2000 Years at Point Barrow, Alaska

Eustatic rises of sea level between A. D. 265 and 500 and between A. D. 1000 and 1100 caused the formation of raised beaches. After the first rise, sea level dropped about 2 meters below the present level, permitting Eskimo settlement of Birnirk about A. D. 500. The second rise of the ocean flooded...

Description
Summary:Eustatic rises of sea level between A. D. 265 and 500 and between A. D. 1000 and 1100 caused the formation of raised beaches. After the first rise, sea level dropped about 2 meters below the present level, permitting Eskimo settlement of Birnirk about A. D. 500. The second rise of the ocean flooded Birnirk. At present, sea level is about 0.6 to 1.0 meter below the high-water levels; the ocean partially floods Birnirk.
