<div><p><strong>Oxygen Isotope data, GLOBEC and Canadian Cruises 1994-1998</strong></p>
<p>Oxygen isotope data are derived from water samples collected on GLOBEC broad-scale and contemporaneous Canadian cruises 1994-1998. The isotope ratio H<sub>2</sub><sup>18</sup>O/H<sub>2</sub><sup>16</sup>O is measured, using a VG Prism II mass-spectrometer operated by Rick Mortlock and maintained by Rick Fairbanks at LDEO, and presented in delta<sup>18</sup>O notation where:<br />
- Replicates of each water sample are analyzed. The data presented is the average of the replicates and their difference. If the difference exceeds 0.066 the analysis is repeated. The average standard deviation of the data is 0.033.<br />
- The content of the data file varies according to source, degree of editing, and some arbitrary formating changes. For broad-scale data the cruise is always given in the file name and sometimes the header. The station number is the broad-scale standard station with associated lat., long., and bottom depth. Temperature, salinity, bottle depth, and sometimes fluorescence and transmissivity data are copied from the broad-scale hydrographic data file.<br />
- Canadian data are from C.S.S. Parizeau cruises. The station and bottle number are unique to a particular cruise. When depth is listed as pressure it is numerically equivalent to depth in meters. Hydrographic data are supplied by Gary Bugden at the Bedford Institute of Oceanography.<br />
- The time for each file is denoted by month and year. More precise day and hour information is available in the original hydrographic file.</p>
