CalCOFI 0511NH CTD Data Notes
CalCOFI 0511NH occupied 72 of 75 scheduled stations; stas 83.3 100, 83.3 90.0,
83.3 80.0 were missed due to rough weather. So 63 standard stations and 9 SCCOOS
stations were done.
Sensor data quality was atypically bad especially on the secondary sensors. Many
troubleshooting attempts did remedy the problems. Some data were lost on either
downcast or upcast but fortunately not both except when powering the ISUS was an
issue. Batteries were swapped after every 3 casts since charging the battery on
the rosette was not implimented yet. Forgetting to unplug the battery could cause
fewer than 3 casts to be powered.
Casts 001 -019 had the SCUFA fluorometer. Casts 020 - 072 had the Seapoint fluorometer.
These casts were processed separately so different regression coefficients from the 
SCUFA vs bottle chla samples & Seapoint vs bottle chla samples could be applied.
Due to the noisy nature of the New Horizon seacable, both Loopedit and Wildedit
Seabird modules were applied. Please refer to each casts hdr file for specific module
settings and order of application.
All other CTD sensors were not changed during the cruise. There were configuration 
(cabling) issues with the T1/C1 & T2/C2 on the first 3 casts. But these were sorted out
and the .asc files should be fine.
Please refer to text file: FirstThreeCastTCConfig.txt for specific sensor ids.

Reprocessing in 2019 used the original final .asc files to merge with bottle data.
Although new .asc files were generated using wfilter applied to ISUS and other data.
These specific columns were imported into the CTD.csvs that were generated from the original
2011 merging of final bottle data & CTD data. Additionally, tranmissometer data were missing
from the 2011 CTD.csvs so these data columns, BAT (beam attenuation coefficient) & XMiss 
(% transmission) were also imported. The original M & B were used, not recalculated.

Other cast issues noted during processing:
Mislabel line.sta in .hdrs: 
Cast 030 Line.Sta was misformatted as 90.27.7; corrected to 90.0 27.7
Cast 052 Line.Sta was misformatted as 83.40.6; corrected to 83.3 40.6
Cast 077 Line.Sta was misformatted as 90.37; corrected to 90.0 37.0
Other casts had integer Line.Sta but these were parsed correctly

Data issues:
Cast 030 downcast salinities ~4-6m were high so data coded "8" (questionable)
Cast 066 downcast temperature 2 and salinity 2 were bad (biofouling) from 44-87m. These
  data were flagged "9" and nulled. The .bak file is available in the bak subdir if you 
  want to see the original values. 
Cast 070 upcast salinity 2 was bad so data coded accordingly; downcast looks fine.
