GIF Natural Radiocarbon Measurements VI

Abstract

This list consists mainly of dates obtained from analysis during 1967 and 1968 of archaeologic and geologic samples. The last section deals essentially with climatic, palynologic, and sea level variation problems. All measurements of atmospheric CO₂ made periodically from 1962 until end of 1970 are also published here. In agreement with international convention, all dates have been calculated on the basis of the C¹⁴ half-life of 5568 years and 95% of NBS oxalic acid as the modern reference year.
