Dating cave drip water by tritium


A relationship between tritium and electrical conductivity in surface water was found to be indicative of water provenance and anthropogenic influences such as agricultural runoff. All of the studied drip sites yielded drip water ages between 2 and 4 years with uncertainties on the order of 1 year. Superimposed on that trend, elevated tritium concentrations are found in the San Francisco Bay area compared to other coastal areas, resulting from municipal water imported from inland mountain sources and local anthropogenic sources. Summary The tritium concentration in the surface hydrosphere throughout California was characterized to examine the reasons for spatial variability and to enhance the applicability of tritium in hydrological investigations. These results were confirmed at several drip sites by oxygen isotope data which show rather constant values with insignificant intra-annual variability. Surface water samples show a trend of increasing tritium with inland distance. Despite low initial concentrations in precipitation, tritium continues to be a valuable tracer in a post nuclear bomb pulse world. One promising approach in determining this residence time is drip-water dating by tritium 3H. The approach was tested in three adjacent caves in northwestern Germany which were monitored for about two years. All of the studied drip sites yielded drip water ages between 2 and 4 years with uncertainties on the order of 1 year. Eighteen precipitation samples were analyzed and samples were collected from surface waters across California in the Summer and Fall of , with repeat samples from some locations collected in Winter and Spring of to examine seasonal variation. Show more authors Abstract Speleothems are increasingly used as an archive of past climate, but some of the proxy signals encoded in these deposits reflect hydrological characteristics of the karst aquifer and not necessarily climate variability.

    A central aspect in karst hydrology is the time required for the rainwater to reach the point of discharge in a cave, e. Surface water samples show a trend of increasing tritium with inland distance.
