Scanfish CTD data were processed using the Sea-Bird Data Processing routines to filter, align, and bin-average data. In 2003 and 2004 dissolved oxygen was calibrated using a two step process. First, the shipboard CTD data was calibrated to niskin bottle samples using a Winkler titration performed in the lab of Nancy Rabalais. Then the Scanfish CTD were cross-calibrated to the shipboard CTD. In subsequent years, the shipboard CTD was pre-calibrated before our cruises, and we cross-calibrated the shipboard and Scanfish CTDs. The calibration between the Scanfish and shipboard CTDs was done in excel using a regression analysis to compare data from the same depths between the two instruments.

<p><b>BCO-DMO Processing Notes</b><br />
<i>BCO-DMO Pass 1 Processing Description:</i><br />
- SCANFISH for years 2003, 2004, 2006, 2007, 2008, 2010 processed<br />
- Original data for individual years were reformatted to a BCO-DMO format as reported using either excel or an awk<br />
- Parameters/Data for the individual years were compared and a common set of parameters for all years was generated<br />
- Pass 1 data were then formatted to the Pass 2 or common data format using awk: NGOMEX_20[xx]_Fix_BCODMO_Scanfish.awk<br />
<br />
<i>BCO-DMO Pass 2 Processing Description:</i><br />
- Because of the nature of the original data reporting, an awk was generated for each individual year<br />
- A common header record was output for each year's worth of data<br />
- All parameters re-formatted to a set of parameters common to all NGOMEX SACFISH data<br />
- All parameters o/p in the same order<br />
- All decimal places reported to the same number<br />
- Data for parameters for which no data were reported for a particular year o/p as &quot;nd&quot;</p>
