Short summary
Improvements and limitations to the measurement δ2H and δ18O of pore waters in geologic core samples using laser spectrometry are presented. These included the use of a δ2H spike to assess the extent of drill fluid contamination and the effect of storage time and type of sample bag on pore water values.
