Please note that the anomalies are based on 50-year harmonics and that these data are direct from the CTD and have not gone through thorough quality control checks. They are presented to give a general impression of current conditions. Final data plots will be published after all data are processed.

General CTD Notes
Casts affected - 004 93.3 28.0; 005 93.3 30.0; 006 93.3 35.0
2017 note on RINKO data: it was discovered during the 2017 reprocessing, that casts 005, 007, & 026 had pressure-to-depth calculation errors in the downcast RINKO data provided by ODF. These data have been corrected in the 'finalQC' CTD.csvs.
08Mar2017 other than the RINKO error mentioned above, the reprocessing adds data-quality code columns and data codes on bad or missing data ("9"), or questionable data ("8"). Data values should not have changed from the previously published final CTD data. But the column number on updated CTD.csvs has changed from 65 to 82.
Cast notes - (unusually) significant issues this cruise with non-confirmation of bottle closures:
2017 Updates - Re-merged the CTD asc files with sta.csvs to generate new CTD.csvs with data quality code columns.
Specific cast notes 2017:
Cast 005: The upcast had ISUS sensor drop-outs from 458-437m, these data were edited out of the upcast csv and data coded.
Casts 009-012: ISUS battery was not powering the sensor so there are no data; data codes have been added.
Cast 037: ISUS signal loss 133-118m on upcast; bad data removed and missing depths data coded.
Cast 044: very slight hiccup in ISUS data at depth in both downcast and upcast files. 502-516m downcast ISUS data
Cast 045: ISUS signal loss 482-437m on upcast; bad data removed and missing depths data coded. Recommend cruise-corrected
Cast 047: mild problem in ISUS data at depth in both downcast and upcast files. 514-515m downcast ISUS data
Cast 048: upcast-only ISUS signal loss from 393-378m & 134-119m; bad data removed and missing depths data coded.
Cast 065: data look like they may improve if loopedit was used. SIO-CalCOFI does not typically apply loopedit to
Cast 069: downcast ISUS data dropouts between 75-111m; data removed and data codes added.
Cast 073: downcast looks fine but upcast may have had a bio-fouling problem. Upcast salinity, and oxygen data do
On CalCOFI 1210NH, a RINKO optode oxygen sensor was deployed on 51 CTD-Rosette casts. Along with the RINKO sensor, a Seabird SBE43 oxygen sensor functioned as the primary oxygen sensor for the cruise. There were 75 stations in total - on 24, an altimeter was needed so the RINKO sensor was disconnected & dummy plugged. On casts 005 - 024, 026, 036 - 052, 061 - 067, the RINKO was mounted vertically; on casts 068 - 072, the RINKO was mounted horizontally.
RINKO oxygen values were very close to Winkler titration oxygen sample values. Comparison of RINKO oxygen data to processed non-bottle corrected SBE43 oxygen data were significantly different (~-0.6 ml/L). Bottle-corrected SBE43 oxygen values, which SIO-CalCOFI considered the best data, did not significantly differ from either RINKO or bottle values (>0.1ml/L). Based on these very preliminary comparisons, if bottle oxygen calibration samples are not available, the RINKO optode oxygen sensor would provide significantly better data than the SBE43.

VESSEL: R/V New Horizon (SIO) Cruise 1210-NH.
CRUISE DATES: October 19 – November 5, 2012.
PROJECT: CalCOFI Survey, Fisheries Resources Division.
ITINERARY: Depart San Diego, California at 0800 on October 19, 2012.
Calibration of the Simrad EK60 echosounders will be performed at the beginning of the cruise (requiring 4 - 6 hours). The ship will
anchor in San Diego Bay, San Diego, and calibrate. After small boat transfer of calibration team, the ship will proceed to the
first CalCOFI station 93.3/26.7 (position 32° 57.4'N/117° 18.3'W) and begin a standard CalCOFI pattern (see attached cruise track).
The vessel will return to San Diego, California on November 5, 2012.
