Argon concentrations in the ocean: A discussion

Because of the importance of argon as a conservative gas tracer in the oceans and as the only rare gas measured both by mass spectrometry and gas chromatography, critical evaluation and comparison of data measured by the two methods is essential. The use of isotope dilution methods in the mass-spectrometric analyses has produced essentially identical precision and accuracy as have been obtained by gas chromatography and the latest Pacific data are in good agreement, especially below 1000 meters depth. The recent data of Bieri et al. provide significant new evidence for the processes we have proposed as responsible for extrema in the saturation anomalies. The data are also consistent with calculations of diffusional losses of the rare gases in northward flowing bottom water in the Pacific.
