The H3+ factor was measured daily prior to dD analysis, with a mean value for the measurement peri- ods of 15.6 ± 0.3 (1r). An external FAME isotope standard (Mix F8, Indiana University Biogeochemical Laboratories) and an internal laboratory isotope standard, measured after every four to six sample analyses, were used to standardize and normalize sample isotope values. The precision of the standard analyses was 6±5& for dD analyses and 6±0.5& for d13C analyses. Most samples were run in duplicate or triplicate for both hydrogen and carbon isotope analysis, and the reported isotope ratio values are averages of replicate runs.
