Radiocarbon dating of shells from marine Holocene deposits in the Disko Bugt area, West Greenland
Shells were collected from marine sediments in the area youth of Disko Bugt from various altitudes up to 50 m. Radiocarbon dates showed that only some of the shells were from sands and gravels formed at or near sea level and could be used to date the land/sea level changes. The shell dates show a re...
