Study region: A paleo-megafan system of the Cubango River in the northern parts of the semi-arid Cuvelai-Etosha Basin, shared by Angola and Namibia. It hosts a deep freshwater aquifer, the so-called Kalahari-Ohangwena 2 (KOH-2), with the potential to

We present a method for improving detection limits of Atom Trap Trace Analysis for the krypton radioisotopes 85Kr and 81Kr. For the case of 85Kr this work demonstrates that systematic use of isotopically depleted gas for calibration and extended cond

In central California, irrigation seepage perturbs groundwater inorganic carbon chemistry and complicates radiocarbon dating.
Groundwater is an important source of drinking and irrigation water. Dating groundwater informs its vulnerability to co

81Kr (T1/2 229.000 a) ist ein idealer Datierungstracer fur alte Tiefengrundwasser. Die Oberjura-Formation im tiefen Teil des Molassebeckens stellt ein herausragendes Georeservoir fur thermale Tiefenwasser (bis 140 °C) dar. Uber die genutzten Thermal

Radioactive noble-gas isotopes tracers 81Kr and 39Ar are used for the first time to measure the residence times of deep (∼1000 m) saline coastal groundwater, and to determine its connection mode with the sea. The average rate of seawater intrusion

36Cl and 81Kr (half-lives of 301 and 229 kyr, respectively) are among a very few age tracers with dating capabilities in the 104–106 yr timescale. Although widely applied since the 1980s in various hydrological studies, the 36Cl/Cl system has been
