As soon as cruise data become available on the park network after completion of SOP 5, the performance of the CTD is reviewed by generating a set of profile plots from all of the HEX files. Sea-Bird SBEDataproc.exe software is used. Due to the number of parameters recorded, each cast requires two JPEG file plots in order to display all values. It is important to perform this procedure immediately after each cruise, so the leader can detect faulty performance of individual sensors in time to complete repairs before the next cruise. (This quality check does not, however, replace the visual file inspections performed in SOP 5. Incorrect length data lines detected in SOP 5 typically indicate defects in the CTD hardware, firmware, and/or configuration but not in individual sensors.) This process is the responsibility of the Project Leader. The plots are intermediate products local to the park and are not a formal SEAN deliverable. They are, however, required so the Project Leader may create the OC_M data quality evaluation deliverable at season’s end. Note: before executing this procedure, it may be helpful to review Appendix H regarding standard directory structures and Appendix I regarding Sea-Bird software layout.
