Natural Radiocarbon Measurements on Surface Water from the North Atlantic and the Arctic Sea

Abstract

An apparatus for the extraction of carbon dioxide from 100 liters of sea-water using carbonate-free sodium hydroxide solution as absorbant liquid and its performance is described. A test series of 6 sea water samples is presented, on which natural C14 determinations are made and the results obtained are briefly discussed in relation to other age measurements on similar waters. The correlation between salinity and C14 activity is shown.
