The 14C age of the Icelandic Vedde Ash: implications for Younger Dryas marine reservoir age corrections

Abstract

Uses terrestrial and marine AMS 14C dates from the time of deposition of the Icelandic Vedde Ash to examine the marine 14C reservoir age. This changed from its modem North Atlantic value of c400 yr to c700 yr during the Younger Dryas climatic event. The increased marine reservoir age has implications for both comparing climatic time series dated by 14C and understanding palaeoceanographic changes that generated the increase. -from Authors
