14c dating groundwater

Because of the long residence time for groundwater in the hydrologic cycle, the last few decades have seen expanding study of groundwater systems.It is therefore important to continually refine our interpretation of hydrogeologic, geochemical and isotopic data to better understand the spatial and temporal movement of water in the subsurface.If the C of the stream DIC is determined, in theory one can calculate the relative contributions of these two sources of carbon to the production of stream or groundwater DIC and carbonate alkalinity.This assumes that: (1) there are no other sources or sinks for carbon, and (2) calcite dissolution occurs under closed-system conditions (Kendall et al., 1992).uses cookies to personalize content, tailor ads and improve the user experience.

With our ever-increasing understanding of the magnitude of climate variations during the last 40 000 years and the impact of our industrialised society on groundwater quality and quantity, hydrogeologists will continue to require more information about the rate of groundwater movement on scales from the subannual to millenium.C and other radioisotopes and techniques used in archaeological, geophysical, oceanographic, and related dating. We also publish conference proceedings and monographs on topics related to our fields of interest.This was a necessary step in the process of dissolved inorganic carbon (DIC) precipitation but not for the gas strip method used by our lab.Please let us know if your samples contain salt or have been in the proximity of any location using labeled 14C (artificial 14C).

The isotope fractionation in the system COC values of dissolved inorganic carbon (DIC) in subsurface waters are generally in the range of -5 to -25 ‰.
