Abstract:

This is a set of bulk sediment analyses of 230Th, 232Th, 231Pa as well as uranium isotopes in surface sediments from the continental slope of the Argentine basin. Samples were subject to full digestion, and radioisotope data were determined using isotope dilution after ion chromatographic separation, electroplating and counting via alphaspectrometry (233Pa yield tracer: beta-counting) by Steffen Niemann as part of his diploma thesis in 2003 (supervision FU Berlin- Prof. Heubeck/ AWI Bremerhaven-Dr. Walter Geibert and Prof. Michael Schlüter).
