Table 5. Mixing end-members for modern LIS waters (element data in ppm, stable isotope ratios in ‰). Sr isotope data are from the Hudson River (PALMER and EDMOND, 1989; 1992). Elemental analysis are a composite from data from the Connecticut River, Thames River and Housatonic River (VAREKAMP, unpublished data). The d 18O values are after ROZANSKI et al. (1993) and the d13C data are after ANDERSON and ARTHUR (1983).
