Extract
This date list covers a selection of 14C results of hydrologic samples investigated from January 1978 until August 1979. According to convention, the ages were calculated with a 14C half-life of 5568 yr and 0.95% of the activity of NBS oxalic acid standard and are quoted in years before 1950. The recent activity of water is assumed to be 90% modern (Geyh and Kreysing, 1973) and corrections for 12C/13C isotopic fractionation have not been made.
