Biography

Present research/professional speciality: Since 1998, Dr Morgenstern has led the Isotope Hydrology team and managed the Water Dating Laboratory at GNS Science. His scientific expertise centres on the use of isotopic methods, such as tritium and 32Si, for determination of the age of water, ice, and sediments. A recent international assessment conducted by the IAEA has shown that, under Dr. Morgensterns management, the GNS Science Water Dating Lab has become the worlds most accurate tritium analytical facility (by a large margin). The information derived from the age measurements is crucial for reconstruction of past global climate and for management of groundwater and surface water resources. Research leadership: New Zealand Ice Core Programme GNS Science Hydrogeology Core Programme
