Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make +4. Cruise has a 4 xovers of
reasonable quality here: 3 with A05 (all suggesting cruise to be ~4 low), 1 with
TTONAS (suggesting cruise to be accurate).
Posted by svheuven@gmail.com on 2015-01-08 16:40:57 UTC for data product: CARINA, GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023
06MT19970107 - tco2
The cross-overs done with a 5 degree limit show that, if anything, the cruise
has higher TCO2 values than other cruises in the region. Due to the location of
the cross-overs (Mediterranean outflow) and the spread of the cross-over values,
it was agreed to change the adjustment to -888.
Posted by denis.pierrot@noaa.gov on 2009-05-18 18:42:16 UTC for data product: CARINA, GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023
06MT19970107 - tco2
The only xover with 33RO19980123 indicate that 06MT19970107 has low values, but
doing some more xovers with 5 degree of latitude limit, results seem not to
support this.
In fact, except with 74DI20040404 and 33RO19980123, xovers with other cruises
seem to indicate that 06MT19970107 cruise is high comparing to the others. (ref:
http://carboocean.ifm-geomar.de/adjustments/plot/102889)

06MT19970107 - tco2
During the Paris meeting it was decided to give TCO2 an adjustment of 5, even
though there is only one cross-over.

06MT19970107 - tco2
Only a single crossover value.
Therefore I feel there is insufficient data to suggest an adjustment or not.

There are 8 xovers when increasing radius limit to 5º (555 km).
The fitted offset is -2.8. The suggested adjustment is 0
All residuals fits inside +-5.
Good fit with GLODAP.

06MT19970107 - phosphate
This cruise covers only a very small region close to the Canary Islands.
The average of all cross overs is 1.098, but this is heavily biased due to one
outlier.
The inversions sugest a downward adjustment of 0.71 (also biased).
The cross-overs with the two repeats of the A05 line suggest that an upward
adjustment of 1.05 is right.
Based on the cross-overs with the two repeats of the A05, I suggest an
adjustment of 1.05.

This cruise covers only a very small region close to the Canary Islands.
The average of all cross overs is 1.007 suggesting the nitrate values are OK.
The inversions sugest a downward adjustment of 0.95.
The cross-overs with the two repeats of the A05 section confirms that the
06MT19970107 nitrate is OK.
Based on this, I suggest no adjustment of the nitrate values.

GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -888. According to WOA2009,
above 2000m, SIL shows a strong latitudinal gradient going from ~25 umolkg south
of Canary Islands to ~17.5 umolkg north of them. Below 2000 meters values are
much more latitudinally stable. One would expect good match between cruises at
depths >2500 or so, but possible offsets <2000m. However, this cruise compares
fair with all others above 2000m, but has much too low values below 3000m. Why?!
Scrub SIL data >3000m? For now, make -888

06MT19970107 - silicate
This cruise covers only a very small region close to the Canary Islands.
The average of all cross overs is 0.86.
The inversions sugest an upward adjustment of 1.09.
The cross-overs with the two repeats of the A05 section indicates that the
06MT19970107 silicate needs to
be adjusted upward.
Based on the above, and the crossover with 33RO19980123, I suggest an upward
adjustment of 1.13 for silicate.

06MT19970107 - oxygen
The average of all cross-overs is 1.027 (only 3), but with one offset that bias
the results and that should not be considered in the inversion.
Indeed, 64TR19890804 has only one station that intersect the 06MT19970107
cruise.
Without this cruise the average would be 1.048 revealing that this cruise is
higher in oxygen.
This cruise needs a downward adjustment but the inversion suggest an upward
adjustment because of the 64TR19890804 cruise that has really small stdv and so
more weight.
On the base of the two offsets between two core cruises (1.033 with 33RO19980123
and 1.063 with 74DI20040404), and on the fact that the 33RO19980123 need a
downward adjustment of 0.988;
I suggest a downward adjustment of 0.948 for the oxygen values for the cruise
06MT19970107.
Zurich, 2008.06.11
During the meeting in Paris we agreed to an adjustment of 0.95
Ilaria Stendardo
The latest inversion (the reduced one without the some AMS cruises and the
06MT19920322 splited into 3 cruises) suggests almost the same adjustment (0.944)
that we proposed during the meeting in Paris, revealing the consistent of our
suggestion.

06MT19970107 - tco2
The cross-overs done with a 5 degree limit show that, if anything, the cruise
has higher TCO2 values than other cruises in the region. Due to the location of
the cross-overs (Mediterranean outflow) and the spread of the cross-over values,
it was agreed to change the adjustment to -888.

06MT19970107 - tco2
The only xover with 33RO19980123 indicate that 06MT19970107 has low values, but
doing some more xovers with 5 degree of latitude limit, results seem not to
support this.
In fact, except with 74DI20040404 and 33RO19980123, xovers with other cruises
seem to indicate that 06MT19970107 cruise is high comparing to the others. (ref:

The average of all cross-overs is 1.027 (only 3), but with one offset that bias

Indeed, 64TR19890804 has only one station that intersect the 06MT19970107
cruise.
Without this cruise the average would be 1.048 revealing that this cruise is
higher in oxygen.
This cruise needs a downward adjustment but the inversion suggest an upward
adjustment because of the 64TR19890804 cruise that has really small stdv and so
more weight.
On the base of the two offsets between two core cruises (1.033 with 33RO19980123
and 1.063 with 74DI20040404), and on the fact that the 33RO19980123 need a

I suggest a downward adjustment of 0.948 for the oxygen values for the cruise

This cruise covers only a very small region close to the Canary Islands.
The average of all cross overs is 1.098, but this is heavily biased due to one
outlier.
The inversions sugest a downward adjustment of 0.71 (also biased).
The cross-overs with the two repeats of the A05 line suggest that an upward
adjustment of 1.05 is right.
Based on the cross-overs with the two repeats of the A05, I suggest an
adjustment of 1.05.
