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.

datapoints, but many many shallow ones, so worth retaining. Deep data gives no
impression of being appreciably biased.

31AN19890420 - tco2

The average of all cross overs (manual) is -4.01.
The average of all cross overs (automatic) is -3.09.
Crossovers with core cruises only suggests offsets of -5.50(manual) and
-2.33(automatic) (with crossover with 64TR19900701 omitted - this is a poor
cruise)
For these crossovers, manual assessments completed 3, whilst the automatic
cluster method performed 5. Therefore, the automatic approach is better.
The inversion suggests an upwards adjustment (2.37 and 1.37 for WLSQ and WDLSQ,
respectively).
These values all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support the inversion results.
Based on this I don't suggest any adjustment for the 31AN19890420 tco2 values.

31AN19890420 - oxygen

The average of all cross overs is 1.004.
The inversions suggest no adjustment.
The cross-overs with the core cruises supports no adjustment.
Based on this I suggest no adjustment to the oxygen values.

31AN19890420 - alkalinity

31AN19890420
alkalinity

The average of all cross overs is -9.6
The inversions suggest an adjustment of -10
The cross-overs with the core cruises support very well the proposed offset.
Also GLODAP 317519930704 support this adjustment

31AN19890420 - silicate

The average of all cross overs is 1.039.
The inversions suggest no adjustment.
The cross-overs with core-cruises are inconclusive, with a lot of scatter in the
data.
Based on these evidence I suggest no adjustment.

31AN19890420 - phosphate

The average of all cross overs is 1.010.
The inversions suggest an adjustment of 1.12.
The cross-overs with core-cruises supports no adjustment.
It seems that the inversion is biased in this case.
Based on these evidence I suggest no adjustment.

31AN19890420 - nitrate

The average of all cross overs is 1.011.

The N/P ratio is 16.33, intercept is -0.36.

The inversions suggest no adjustment.

The cross-overs with core-cruises supports no adjustment.

Based on these evidence I suggest no adjustment.
