<div><p>Data were collected using the ship's CTD package (SBE911+). Note that the ship’s first& CTD, used at Station 1, was lost at station 2. A second CTD package was later obtained and used at stations 5-12. (Refer to the 'Problem Report' below for more information.)</p>
<p>Also note that a second CTD package (Trace Metal Rosette (TMR), SEACAT 19+) was also used for sampling at some stations. See the "TMR Hydrography dataset" (<a href="https://www.bco-dmo.org/dataset/716685" target="_blank">https://www.bco-dmo.org/dataset/716685</a>) for these related data.</p></div>

<p><strong>Problem Report:</strong><br />
The entire rosette, including the CTD sensor package, came free from the hydrowire at Station 2 and was never recovered. A reconstituted, but limited, sensor package was assembled by Station 5. Details given above refer either to the 'first package' (Station 1) or 'second package' (Stations 5-12). Gaps in the dataset were filled using CTD data from the sensor package on the trace metal clean rosette (TMR), deposited as a separate dataset in BCO-DMO.</p>
<p>No ship's CTD data were taken at Station 11.</p>
<p>Surface (0-10 m) oxygen data are suspect.</p>
<p><strong>BCO-DMO Processing:</strong><br />
- modified parameter names to conform with BCO-DMO naming conventions (removed spaces, replaced "/" with underscores);<br />
- replaced blanks (missing data) with "nd";<br />
- converted longitude values from positive to negative to indicate West.</p></div>
