  • BOTTOMWATER FORMATION DUE TO HYDROTHERMAL ACTIVITY IN FROLIKHA BAY, LAKE BAIKAL, EASTERN SIBERIA 
    Kipfer R.; Aeschbach-Hertig W.; Hofer M.; Hohmann R.; Imboden D.M.; Baur H.; Golubev V.; Klerkx J. (1996)
    Hydrothermal water enters Frolikha Bay, a well-known site of high geothermal heat flux in the northern part of Lake Baikal, at 400 m depth. On the basis of CTD profiles, the hydrothermal water is identified as forming an ...
  • EXPERIMENTAL INVESTIGATIONS ON THE FORMATION OF EXCESS AIR IN QUASI-SATURATED POROUS MEDIA 
    Holocher J.; Peeters F.; Aeschbach-Hertig W.; Hofer M.; Brennwald M.; Kinzelbach W.; Kipfer R. (2002)
    The formation of an excess of dissolved gas (''excess air'') in quasi-saturated media was studied by analyzing and interpreting dissolved noble gas concentrations in laboratory column experiments. Using quartz sand filled ...
  • IMPROVING NOBLE GAS BASED PALEOCLIMATE RECONSTRUCTION AND GROUNDWATER DATING USING 20NE/22NE RATIOS 
    Peeter F.; Aeschbach-Hertig W.; Holocher J.; Brennwald M.S.; Kipfer R.; Beyerle U. (2003)
    The interpretation of noble gas concentrations in groundwater with respect to recharge temperature and fractionated excess gas leads to different results on paleo-climatic conditions and on residence times depending on the ...
  • ISOTOPIC METHODS AND THEIR HYDROGEOCHEMICAL CONTEXT IN THE INVESTIGATION OF PALAEOWATERS 
    Loosli H.H.; Aeschbach-Hertig W.; Barbecot F.; Blaser P.; Darling W.G.; Dever L.; Edmunds W.M.; Kipfer R.; Purtschert R.; Walraevens K. (2001)
    Isotope and geochemical techniques are the primary way in which the residence time, recharge conditions and subsequent evolution of palaeowaters can be determined. Isotopic species and noble gas concentrations are used as ...
  • NOBLE GASES IN LAKES AND GROUND WATERS 
    Kipfer R.; Aeschbach-Hertig W.; Peeters F.; Stute M. (2002)
    In contrast to most other fields of noble gas geochemistry that mostly regard atmospheric noble gases as 'contamination,' air-derived noble gases make up the far largest and hence most important contribution to the noble ...
