Comment:
87Sr/86Sr values for standards equal 0.710265 for NBS 987, and 0.709175 for seawater samples from the North Atlantic and Central Pacific. Ratios are fractionation corrected to an 86Sr/S8Sr ratio of 0.1194. All samples have been assigned a minimum uncertainty of +/- 22 * 10**-6, equivalent to the variability of repeated analyses of NBS 987
