Changed 06M320110624 for GLODAPv3 to 06MT20110624

GLODAPv3: for consistency changed expocode of adjustment from 06M320110624 to
'erratic' 06MT20110624

Posted by nlange@geomar.de on 2026-07-25 18:24:25 UTC for data product: GLODAPv3

06M320110624 - c13

Becker et al. 2016:
These cruises are also known as M39 cruises with three legs
of 13C-DIC sampling (M39-2, M39-3, M39-4). Since each
leg of this cruise had only a few stations with 13C-DIC
samples, and all these samples were analyzed together, these
cruises were summarized for the crossover study. Neither the
inversion routine nor the single crossover with the adjusted
cruises show evidence for an offset.

06M320110624 - salinity

Offsets strongly depend on the location and time, e.g. Hudson vs "North
Atlantic" crossovers.
Following the weighted mean and the most recent crossovers no adjustment
suggested.

Posted by nlange@geomar.de on 2018-05-25 08:29:32 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06M320110624 - cfc11

The saturation mixing ratio points towards too high CFC_11 concentrations.
However, it is still within the accepted range and the data fits good to the
CFC_12 data, too. No adjustment.

Posted by nlange@geomar.de on 2018-04-26 14:06:08 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06M320110624 - cfc12

The saturation ratio of the upper 20m points towards too high CFC_12
concentrations. However, given the good fit to the CFC_11 data and given the
threshold limit no adjustment should be applied.

Posted by nlange@geomar.de on 2018-04-26 14:03:19 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06M320110624 - oxygen

Many crossovers present. Most of the offsets are within the acceptable range,
which is also reflected in the total weighted mean offset being very close to 1.
Given the large variability and high number of acceptable offsets there is
Little to no reason for an adjustment.

Posted by nlange@geomar.de on 2018-04-26 13:59:10 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06M320110624 - salinity

Temporal trend in salinity concentrations visible, resulting in more negative
offsets for older cruises, esp. cruises older 1998. Hence the total weighted
mean offset of -0.01 should not be used as an indication for an adjustment. Many
of the more recent cruises even have positive offsets, in some cases even above
the limit, e.g. 06MM2009. All in all no adjustment should be applied.
