The hydrosphere encompasses water on earth in its entirety and thus permeates all compartments of the environment. The hydrological cycle is a central part of the global climate system and replenishes vital freshwater resources in lakes, rivers and aquifers. In addition, water and ice store information on the climate of the past. The HydroTraP group uses krypton dating trace elements, compounds and isotopes tracers contained in liquid water as well as in ice for age dating, to obtain information on the chronology of archives and the dynamics of surface and subsurface waters as well as glaciers. Atmospheric noble gases and water isotopes additionally serve as proxies for environmental conditions during the formation of water and ice masses, such as past temperatures and other climate parameters. HydroTraP uses these methods to contribute to water resources management as well as for paleoclimate reconstruction. The HydroTraP group deals with the experimental development, methodical improvement and practical application of tracer and proxy methods in the hydrosphere groundwater, lakes, and oceans as well as in climate archives speleothems, glaciers, and aquifers. Our central tools are stable and radioactive isotopes of the noble gases 3 He, 4 He, main isotopes of Ne, Ar, Kr, Xe sowie 39 Ar, 81 Kr, 85 Kr, Rn. Often we use the noble gases in combination with classical methods of isotope hydrology 2 H, 18 O, 3 H and 14 C or with transient environmental tracers SF 6CFCs. Information on many of our current and completed research projects can be found on the pages of DFG GEPRIS Project Details on W. Many projects are connected to thte innovative development of Dating by Krypton dating Trap Trace Analysis ATTA. Additional links to individual projects:. Our experimental methods encompass two compartments: tracers and proxies. Samples are analyzed in different laboratories, partly also on commission. For data analysis and interpretation, different kinds of software have been developed and can be downloaded for free. The following tracers are applied. Further information can be found on our methods page. The laboratories are also part of the Heidelberg Environmental Analytics Platform HEAP of the Heidelberg Center for the Environment HCE. More information can be found here. Analysis of noble gases and tritium can be done on commission. For more information please contact Florian. Freundt iup. Aeschbach iup. Sampling instructions can be found on our methods page. HydroTraP has developed a number of programs for the data analysis of tracers krypton dating proxies. Those software tools are available for download. Inverse determination of model parameters by weighted least squares fitting. There are three programs available: A simple MS EXCEL workbook, a more sophisticated MATLAB routine, and finally the very versatile, stand-alone program PANGA. The old, simpler EXCEL workbook developed by myself is available here: Noblebook. The MATLAB routine developed by Frank Peeters is available at EAWAG: Noble gas fitter. There is new version available since Dec. The new software PANGA developed by Michael Jung is available here: PANGA page. Box-model approaches to interpret 3 H - 3 HeCFC, and 85 Kr data. The software "Boxmodel V3" is a MICROSOFT EXCEL workbook, designed for educational purposes. It has originally been developped by Kai Zoellmann, and later been expanded by myself and used for a Krypton dating by Urs Beyerle. Workbook and documentation are provided here for free download.
