2018 Shelfwide Cruise: July 23 - July 30
The 2018 shelf-wide cruise to determine the extent of low oxygen bottom waters on the Louisiana-Texas continental shelf is dedicated to the memory of Dr. Wesley J. Tunnell, Jr. who passed away on Saturday, July 14, 2018, after a long successful and not successful battle with cancer.

- The final dissolved oxygen data will be corrected, as necessary, from linear regression with the Winkler titrations over a range of 0.22 to 8.43 mg/L. Initial observations indicate correction, but the f-factor for the Winkler standard remains to be verified. Any corrected data will be reflected in other derived measurements.
- Salinity data not yet verified with PortaSal samples.
- CTD data remain to be post-processed with ALIGN CTD to be applied.
- Instrumentation was calibrated pre- and post-cruise according to manufacturer's specifications and standard method procedures were applied for several variables, not yet calculated, according to several LUMCON EPA-approved Quality Assurance Project Plans.
- Data collected as part of process studies remain to be analyzed and synthesized.
- Final QA/QC'd data will be submitted to NOAA NODC within two years of collection.
