Oxygen isotope levels derived from sea water samples, 1994-1997, Georges Bank region, GLOBEC

Water bottle sampling for oxygen isotope analyses were conducted during 25 cruises to the Georges Bank/Gulf of Maine region 1994-1997. The isotope ratio H2O18/H2O16 was measured, using a VG Prism II mass-spectrometer and reported in delta_O18 notation. The data presented are the averages of the replicates and their differences. If the difference exceeded 0.066 the analysis was repeated. The average standard deviation of the data is 0.033. Also reported are environmental parameters of temperature, salinity, fluorescence, light transmission.
