The inversion suggest a correction of -0.42 ppm. This is based on 20 crossovers
with a mean offset of 1.177. Do not adjust. This is consistent with CARINA.

Average of all cross-overs is: 0.8 ppm
Inversion analysis suggests an insignificant adjustment.
Many cross-overs, including those with core cruises, do not warrant an
adjustment.

316N19831007 - tco2
Mean offset with 7 cruises: -6.9 and thus an adjustment seems necessary. Mean
offset seems higher through cruise 06AQ19860627, which itself is much too low by
about 12.
Inversion gives +11.4
We follow CARINA with an adjustment of +8

recommendation. Offsets improve markedly.

316N19831007 - alkalinity
Mean offset with 5 cruises: -8.9 but this is biased towards low value by 2 bad
x-overs (90MS19811009 and 35A319950222). Because of this the inversion suggests
+11.4
I suggest NO adjustment, in agreement with CARINA.

There are 5 xovers. The fitted offset is -0.2. The suggested adjustment is 0
Except one, all inversion residuals fits inside +-5, and three of them are very

Very good fit with the last 3 GLODAP cruises in offsets plot.

make 0.98 / 1.02 / -777. Stations 1-59 have a very clear 2% high bias, which is
easily adjusted for. AJAX-2 (i.e., statno 60 onwards) are 2% low and require
0.98. From station 105 (midway Weddell Section), PO4 is way off and drifts, and
will be flagged BAD as a separate station range starting from statno 95 (from
where SIL is off as well).

Average of all cross-overs is: 0.997 (very low cross-over with cruise

Cross-overs with core cruises (49NZ20031106, SAVE) do not support the suggested

make 1.00. AJAX SIL data up to station 95 (i.e., leg 1 and first half of 2) have
no appreciable bias. Stations 95 and higher (i.e., the Weddell section) have an
approximate +6% bias. See figure AJAX_1_2 SIL_stat, which illustates the jump
versus the WOA09 climatology. Jump also evident in xover plots. Latter range
will b flagged BAD.

more data.

Average of all cross-overs is: 1.029 (but this value is strongly influenced by a

Inversion analysis suggests an adjustment of: 0.972
Core cruise 49NZ20031106 and comparison to other cruises appear to support a

maintain 0.99. AJAX is clearly a bit on the high side (e.g., against RO2005,
RO2010). Average bias is +1.5±2.0% (n=23). I do not believe the Guinea and
Angola basins would be able to show a trend of any observable magnitude over
mere decades, so any bias I consider due to analytical procedures.

The inversion suggest a correction of 0.988, this is based on 18 crossovers with
a mean offset of 1.017. This is a South Atlantic, Southern Ocean cruise. CARINA
suggest a consistent 0.99 adjustment. We recommend that these data are adjusted
using a factor of 0.99.

maintain 0.99. AJAX is clearly a bit on the high side (e.g., against RO2005,
RO2010). Average bias is +1.5±2.0% (n=23). I do not believe the Guinea and
Angola basins would be able to show a trend of any observable magnitude over
mere decades, so any bias I consider due to analytical procedures.

make 1.00. AJAX SIL data up to station 95 (i.e., leg 1 and first half of 2) have
no appreciable bias. Stations 95 and higher (i.e., the Weddell section) have an
approximate +6% bias. See figure AJAX_1_2 SIL_stat, which illustates the jump
versus the WOA09 climatology. Jump also evident in xover plots. Latter range
will b flagged BAD.

316N19831007 - phosphate
make 0.98 / 1.02 / -777. Stations 1-59 have a very clear 2% high bias, which is
easily adjusted for. AJAX-2 (i.e., statno 60 onwards) are 2% low and require
0.98. From station 105 (midway Weddell Section), PO4 is way off and drifts, and
will be flagged BAD as a separate station range starting from statno 95 (from
where SIL is off as well).

316N19831007 - phosphate
New inversion for phosphate in the Atlantic with 10 core cruises assigned
confirms that NO adjustment should be applied.

316N19831007 - tco2
Mean offset with 7 cruises: -6.9 and thus an adjustment seems necessary. Mean
offset seems higher through cruise 06AQ19860627, which itself is much too low by
about 12.
Inversion gives +11.4
We follow CARINA with an adjustment of +8
Posted by mario.hoppema@awi.de on 2012-11-19 16:53:49 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023
316N19831007 - alkalinity
Mean offset with 5 cruises: -8.9 but this is biased towards low value by 2 bad
x-overs (90MS19811009 and 35A319950222). Because of this the inversion suggests
+11.4
I suggest NO adjustment, in agreement with CARINA.

316N19831007 - oxygen
The inversion suggest a correction of 0.988, this is based on 18 crossovers with
a mean offset of 1.017. This is a South Atlantic, Southern Ocean cruise. CARINA
suggest a consistent 0.99 adjustment. We recommend that these data are adjusted
using a factor of 0.99.

316N19831007 - silicate

more data.

Average of all cross-overs is: 0.8 ppm
Inversion analysis suggests an insignificant adjustment.
Many cross-overs, including those with core cruises, do not warrant an
adjustment.

Average of all cross-overs is: 1.029 (but this value is strongly influenced by a
very high cross-over with cruise 316N19831113).
Inversion analysis suggests an adjustment of: 0.972
Core cruise 49NZ20031106 and comparison to other cruises appear to support a

Average of all cross-overs is: 0.997 (very low cross-over with cruise
