摘要：

We investigated surface ocean-atmosphere C-14 offsets for the later Holocene at eight locations in the eastern North Atlantic. This resulted in 11 new Delta R assessments for the west coast of Ireland, the Outer Hebrides, the north coast of the Scottish mainland, the Orkney Isles and the Shetland Isles over the period 1300-500 BR Assessments were made using a robust Multiple Paired Sample (MPS) approach, which is designed to maximize the accuracy of Delta R determinations. Assessments are placed in context with other available data to enable reconstruction of a realistic picture of surface ocean C-14 activity over the Holocene period within the North Atlantic region.
