W. SCHARPENSEEL and F. PIETIG Institut fur Bodenkunde, Universitat Bonn Bonn, Bundesrepublik Deutschland Continuation of radiocarbon measurements, mainly on ground water, soil, and subhydric sediment samples. Sample preparation was described earlier (Scharpenseel and Pietig, 1969). ACKNOWLEDGMENTS Much of the technical sample preparation was done by E. Kruse, H. Tapp, Chr. Haupenthal, H. Schillmann, and K. Kirschey. The Gesell- schaft fur Mathematik and Datenverarbeitung helped us with their computer facilities in the calculations. The work was financed mainly by the Federal Department of Education and Science. Travel funds for sampling outside Germany were provided by the German Foundation of Research (Deutsche Forschungsgemeinschaft). SAMPLE DESCRIPTIONS 1. GROUND WATER SAMPLES A Cologne 07 sand aquifer After 3 yr repetitions of radiocarbon measurements from 1967 to 1969 (R., 1968, v. 10, p. 8-28; 1969, v. 11, p. 3-14; 1970, v. 12, p. 19-39) a 4th sampling and measurement was done in 1971. Since the 3 sets of dates (1967-1969) did not allow flow speed calculation from move- ment of bomb-carbon peak, due to geologic ruptures, mixing and un- steady flow-pattern (Tamers and Scharpenseel, 1970), further tests at intervals of several yr are expected to yield new data.

Two further sets of samples in 2 or 3 yr intervals expected to elucidate rattler complicated flow and recharge pattern of highly exploited aquifer. II. SOIL SAMIPLLS Methods of pretreating soil samples are compared and reviewed else- where (Scharpenseel and Pietig, 1969; Scharpenseel, 1972). A.

Coinmcut: last 2 profiles, El Arahal and Carmona Far show to tlme full depth about the same apparent mean residence time (Scharpenseel, 1972), indicating transport of surface material through cracks and sell-mulching. La Riniconada and Carmona profiles have an age break at ca. 100cm, Los Palacios at ca. 70cm with steep increase of C: residence times in downward direction, below the crack zone. B.
