Geochemical composition of tephra layers from deep sediment core GS16-204-22CC-A,eastern Labrador Sea, south of Greenland

This dataset contains major element oxide data of tephra layers from marine sediment core GS16-204-22CC-A , located in the eastern Labrador Sea, south of Greenland. The core is investigated for increased tephra occurrences and geochemically analysed for the major element composition of tephra shards to identify their source volcano(es)
