(Table 1) Pb isotopes in different bulk sediment fractions from ODP Site 177-1090

Sediment depth is given in mcd. Age model after Channell et al. (2003, datasets: doi:10.1594/PANGAEA.717737). Long term NBS 981 values analyzed over several years on the MC-ICPMS at UF are 206Pb/204Pb=16.937 (2 sigma=0.004), 207Pb/204Pb=15.489 (2 sigma=0.003), and 208Pb/204Pb=36.695 (2 sigma=0.008).
