CalCOFI 9608NH CTD Data Processing Notes

Summary: The single set of primary sensors: temp, cond, O2, worked well this 
cruise and no replacements were required. 

Software: DOS Datcnv(Seasoft exe), running in a Windows XP virtual machine on Windows 7.
Additional Seasoft processing done using v7.23.2 SBE Data Processing. Since no
sensors were changed, a single .xmlcon file was using for all stations in the
Derive module. 
Bottle corrections were applied using BtlVsCTD, SIO-CalCOFI's
in-house CTD sensor & bottle data merging suite.

Corrections:
Cast 001 - line.sta in .hdr was changed from 93.26.7 to 93.3 26.7 for parsing
Cast 050 - line.sta in .hdr was changed from 83.40.6 to 83.3 40.6 for parsing

Casts 054 & 058 were restarted - 054 had an salinity issue that fixed itself
upon retrieval to surface (bio-fouling?). Cast 058 has a winch failure so the
cast was restarted once fixed.

Fluorometer sensitivity was changed prior to cast 050, from 10x to 3x. So casts
001-049 were processed with FlV vs Chla 10x plot correction coefficients (see plot or spreadsheet)
  Extra casts 506, 507, 605, 610, 613, 621, 632, 640 were also processed separately using 1x
  
050-06 were processed with FlV vs Chla 3x plot correction coefficients (see plot or spreadsheet)
  Extra casts 467, 468, 469, 654, 657, 660 were also processed separately using 3x coefficients.

Extra casts (refer to each cast's .hdr files for more info):
No bottle samples were taken so plots are cruise-average CTD sensor data

400s - Rathburn coring station CTD casts 467, 468, 469
469 - Ohman oxygen sensor test - replacing our O2 sensor, Rathburn? - need console ops notes
500s - Miguel (grad student) extra casts 506, 507
600s - Goericke/Miguel extra casts 605, 610, 613, 621, 632, 640, 654, 657, 660

Extra casts were processed in similar fashion as the standard 66 stations but run 
separately. Refer to the "ExtraCasts" folders for these data. There are quite a few
extra metadata files from separate processing of the extra casts. Some of these are extraneous,
since there are no bottle correction coefficients since no bottle samples were taken.

No substantial spikes were visible on inspection so there are no added data flags.
