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.

06MT20010507 - tco2 - no suggested adjustment
06MT20010507 - tco2
No manual crossovers were performed.
The average of all cross overs (automatic) is -1.1.
Crossovers with core cruises only suggests offsets of 0.48(automatic)
Inversion also suggests no adjustment (0.99 and -0.02 for WLSQ and WDLSQ,
respectively).
Automatic results fall within limits.
Inversion results also suggest no adjustment.
Based on this I don't suggest any adjustment for the 06MT20010507 tco2 values.

06MT20010507 - phosphate
The average of all cross overs is 0.891.
The N/P ratio is 14.76, intercept 1.89.
The inversion suggest an upward adjustment of 1.12 and 1.11 for WLSQ and WDLSQ,
respectively.
Most of the cross-overs with the core-cruises confirm that 06MT20010507
phosphate is low.
Based on these evidence I suggest an adjustment of 1.11, in agreement with the
inversion.

Most of the cross-overs witht the core-cruises are close to 1 (within the

Based on these evidence I suggest no adjustment.

06MT20010507 - silicate
The average of all cross overs is 0.956.
The inversion suggest an upward adjustment of 1.12 and 1.14 for WLSQ and WDLSQ,
respectively.
The cross-overs with the core-cruises suggest that 06MT20010507 silicate is
good, but with
large variability in the area. The inversions are biased due to a few outliers.
Based on these evidence I suggest no adjustment for silicate.

Becker et al. 2016:
The inversion routine suggested a correction of -0.24 ‰, whereas the mean offset
was 0.16‰ too high. The MLR analysis revealed an offset of 0.30‰. Based on the
southern crossover with cruise 06MT20040311 and 316N19970717, an adjustment of
-0.30‰ was applied.

Crossovers with core cruises only suggests offsets of 0.48(automatic)
Inversion also suggests no adjustment (0.99 and -0.02 for WLSQ and WDLSQ,
respectively).
Automatic results fall within limits.
Inversion results also suggest no adjustment.
Based on this I don't suggest any adjustment for the 06MT20010507 tco2 values.

06MT20010507 - salinity
offsets are in the North west Atlantic, DSOW salinity low in 2001
adjustment from inversion ignored

06MT20010507 - silicate
The average of all cross overs is 0.956.
The inversion suggest an upward adjustment of 1.12 and 1.14 for WLSQ and WDLSQ,
respectively.
The cross-overs with the core-cruises suggest that 06MT20010507 silicate is
good, but with
large variability in the area. The inversions are biased due to a few outliers.
Based on these evidence I suggest no adjustment for silicate.

06MT20010507 - phosphate
The average of all cross overs is 0.891.
The N/P ratio is 14.76, intercept 1.89.
The inversion suggest an upward adjustment of 1.12 and 1.11 for WLSQ and WDLSQ,
respectively.
Most of the cross-overs with the core-cruises confirm that 06MT20010507
phosphate is low.
Based on these evidence I suggest an adjustment of 1.11, in agreement with the
inversion.

06MT20010507 - nitrate
The average of all cross overs is 0.971.
The inversion suggest an upward adjustment of 1.03 and 1.04 for WLSQ and WDLSQ,
respectively.
Most of the cross-overs witht the core-cruises are close to 1 (within the
uncertainty).
Based on these evidence I suggest no adjustment.
