06MT20040311 - c13

Becker et al. 2016:
The inversion Routine indicates that the 13C-DIC data of this cruise are 0.10‰
too low. Additionally, the mean offset as well as the MLR analysis shows that
these data are too low. An adjustment of 0.10‰ was applied.

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:2; CTD salinity data good, setting CTD salinity offset and QC
flag to bottle values.
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): : maintain 1.00. Not fully
inspected, but inversion says abs(adj)<0.5% and existing suggestion is also
<0.5%

2% high bias, but I'm not convinced by the xover plots.

Autogenerated comment - phosphate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Extreme scatter from
station to station, plus a 4-5% high bias. Recommend -777. MT20040311
(TTO-revisited) PO4 seems to drift against 31AN1981 and DI74AB2005, which do not
drift against each other. Westernmost stations of MT04 are extremely too high
(+10-20%), while stations around 55oW are fine, but easternmost stations are way
high again.

Autogenerated comment - nitrate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.01. Some drift in
calibration evident. Station in east and west seem fine, while central stations
around 50oW are about 2% low.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make +4. This important cruise is
clearly ~4 low against several 'core' cruises (29HE20130320, 316N20030922,
316N20031023, 33AT20120324, 33RO19980123, 33RO20030604 (only ~2.5 low against
that one though)).

06MT20040311 - phosphate

The crossover analysis of the adjusted data suggest that this cruise was
adjusted too much. The average of the crossovers is 0.96 and the inversion
suggest an adjustment of 1.04.
Based on this the adjustment was changed to 0.97

06MT20040311 - silicate

The average of all cross overs is 1.018, suggesting that the silicate values are
good.
The inversion suggest an adjustment of 0.989.
The cross over results with core-cruises confirm that the silicate values for
06MT20040311 are good.
Based on this I suggest no adjustment for silicate for 06MT20040311.

06MT20040311 - phosphate

The average of all cross overs is 1.045, suggesting that the phosphate is a
little bit on the high side.
The metadata states that the quality of the phosphate measurements were not so
good.
The N/P ratio is 14.19, intercept 0.28.
The inversion suggest an adjustment of 0.93.
The cross over results with core-cruises confirm that the phosphate values for
06MT20040311 are too high.
Based on this I suggest an adjustment of 0.94 for phosphate.

06MT20040311 - nitrate

The average of all cross overs is 0.98, suggesting that 06MT20040311 nitrate is
a little bit on the low side,
but not enough to do an adjustment.
The inversion suggest no adjustment.
The cross over results for core-cruises all confirm that 06MT20040311 is OK.
Based on this I suggest no adjustment for nitrate.

alkalinity
There are 15 xovers. The fitted offset is 3.6. The suggested adjustment is 0
All residuals are low and fits inside +-5.
Very good fit with 8 GLODAP cruises. However, some of them seems to suggest a
high offset.

06MT20040311 - tco2

06MT20040311
tco2
The average of all cross overs (manual) is 1.15.
The average of all cross overs (automatic) is 0.73.
Crossovers with core cruises only suggests offsets of 0.58(manual) and
0.49(automatic) - omitting result from 29HE19920714 crossover
Inversion also suggests no adjustment (0.83 and -0.14 for WLSQ and WDLSQ,
respectively).
This cruise is itself defined as a core cruise - the crossover results support
this.
Both manual and automatic results and inversion fall within limits.
Based on this I don't suggest any adjustment for the 06MT20040311 tco2 values.

06MT20040311 - oxygen

The average of all cross overs is 0.994.
The inversions suggest no adjustment.
The cross-overs with other core cruises do not support that an adjustment is
warranted.
Based on this I suggest no adjustment to the oxygen values.
