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.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 0.975. Profiles very noisy,
some scatter between profiles. Borderline acceptable. Is exactly 1.5% high
against RO1998 (which is 0.5% too high itself). Inversion thinks 0.972, so OK.
Adjustment is 1% more negative than that for DI2010

74DI20040404 - silicate

The average of all cross overs is 1.050, suggesting that the silicate is high.
The inversion suggest a small downward adjustment (0.97 and 0.99 for WLSQ and
WDLSQ, respectively).
The cross-oves with the core-cruises suggests that a small downward adjustment
of the 74DI20040404 silicate is justified.
Based on this I suggest an adjustment of 0.98 for the 74DI20040404 silicate
values.

74DI20040404 - phosphate

The average of all cross overs is 1.032, suggesting that the phosphate is a bit
high.
The inversion suggest a small downward adjustment (0.98 for both WLSQ and
WDLSQ).
The cross-oves with the core-cruises, particullarly the 2003 CLIVAR cruises,
suggests that the 74DI20040404 phosphate should not be adjusted.
Based on this I suggest no adjustment for the 74DI20040404 phosphate values.

74DI20040404 - nitrate

The average of all cross overs is 1.027, suggesting that the nitrate is a bit
high.
The N/P ratio is 14.72, intercept 0.61.
The inversion suggest a small downward adjustment (0.96 and 0.97 for WLSQ and
WDLSQ, respectively).
The cross-oves with the core-cruises supports that the nitrate values for
74DI20040404 are high.
Based on this I suggest an adjustment of 0.97 for the 74DI20040404 nitrate
values, in agreement with the WDSLQ inversion.

There are 10 xovers. The fitted offset is 2.4. The suggested adjustment is 0
Most of the residuals fits very close to 0 and keep inside +-5.
Very good fit with 6 GLODAP cruises

74DI20040404 - oxygen

The average of all cross-overs is 1.001.
The inversions suggest no adjustments.
The cross-overs with others core cruises support no adjustment for this cruise.
Based on this I suggest no adjustment to the oxygen value.
