Autogenerated CTD salinity and CTD oxygen update

Automated update! This overwrites adjustment values (and flags) of CTDoxy and
CTDsal with the values from BOTsal and BOToxy for every cruise, unless CTDsal
(or CTDoxy) is not present or bad.
Salinity action ID:3; no CTD salinity data. Setting CTD salinity offset to -999,
QC flag removed.
Oxygen action ID:3; no CTD oxygen data. Setting CTD oxygen offset to -999, QC
flag removed.

318M19740205 - nitrate

At Groningen workshop Oct 2013, we decided to adjust GEOSECS Pacific nutrients
similarly for all legs, based on the offsets of the legs with acceptable xovers,
at the time leg 5,6, 7 and 8 for nitrate. Offsets less than 2% overall.
Reassuringly, Stevens xovers of unadjusted data confirms this for leg 1. Do not
adjust.

At Groningen workshop Oct 2013, we decided to adjust GEOSECS Pacific nutrients
similarly for all legs, based on the offsets of the legs with acceptable xovers,

by 1.03. Reassuringly, Stevens xovers of unadjusted data confirms this for leg
1.

318M19740205 - general

Overall there are not enough good crossovers to do a proper analysis. This is
one of the four GEOSECS Pacific legs that have Xover results. Based on the few
Xovers and what was done in GLODAP, I would not adjust anything other than tco2
and alk which are clearly offset. I suggest we use the same adjustment for tco2
and alk on all GEOSECS Pacfic cruises. In GLODAP small adjustments were made,
the exception being +0.98 on nitrate.
