Pb radiotracers for obtaining information on sedimentation which in a changing coastal environment is subject to erosion, losses of sediments, and deposition of material that had been remobilized before from near-shore sediments in the course of storm surges.
Geochronologies were established for sediment cores taken from salt marsh cliffs on the Isle of Sylt (Germany).
Also here he introduced state of the art data management and laboratory management procedures into the isotope hydrology laboratory.
He developed post-processing algorithms for noble gases, radiometry (gas proportional counters, liquid scintillation counters) and electrolytic enrichment of tritium.
The study described here sought to answer three questions: To answer these questions, the U. Geological Survey (USGS), in cooperation with the U. Environmental Protection Agency (USEPA), collected and analyzed sediment cores from Clear Creek (fig. Sediment cores sometimes can be used to reconstruct historical trends in concentrations of hydrophobic contaminants (Eisenreich and others, 1989; Van Metre and others, 1997). R., , Analysis of risk from consumption of Clear Creek fish: Texas Department of Health report, 34 p.
Cores were collected from five ponds connected to Clear Creek but out of the main channel (fig. Cesium-137 (Cs) was analyzed in the cores to determine if the sediments in the cores were undisturbed and if the cores reached sediment predating 1964.
CEN has the equipment and expertise to prepare samples for AMS dating, which includes 2 major steps: C of your samples can also be done.
Radiocarbon is incorporated into all living organisms in proportion to its concentration in the environment.
When an organism dies, carbon is no longer incorporated into its tissues, but the radiocarbon present continues to decay at a known rate. The Pb-210 and Cs-137 datation service is also offered for sediments.
After Ph D Axel started Laboratory Management in Geochronology and Isotope Hydrology at the Leibniz Institute for Applied Geophysics (at that time: "Geowissenschaftliche Gemeinschaftsaufgaben") in Hannover, and he returned to this laboratory after his time at the IAEA.
Axel was involved in: Sediment dating using gamma spectrometry of 210Pb, 214Pb, 214Bi, 137Cs; Radiocarbon dating using gas proportional counters for 14C; Isotope hydrology using tritium and including electrolytic isotope enrichment as well as stable isotope (18O, 2H) mass spectrometry.
