Insert -999 No suggestion for adjustment possible? Insert -888 To calibrate CTDsal use: CTDsal_calibrated = (CTDsal - CTDsal_intercept) / CTDsal_slope To calibrate CTDoxy use: CTDoxy_calibrated = (CTDoxy - CTDoxy_intercept) / CTDoxy_slope

alkalinity

There were 69 measured samples in original file. I've removed them as we can
compute significantly more values from pH and TCO2. Flag set to -888
accordingly.

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:6; 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.

Autogenerated comment - silicate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.01. One very good
xover, with 32MW19890206, shows this cruise to be 3% too low. However, after
applying precorrections of +1% and -1% to JPN and US cruises respectively, it's
only 1% too low. 32MW is very accuracte, so I opt to increase 49XK19960617 by
that residual 1% (for a total adjustment of 2%, counting that pre-adjustment).
Listed adjustment for SIL for this cruise additionally contains a pre-adjustment
of +1% (default for all Japanese Pacific SIL data).

49XK19960617 - silicate

49XK19940212 and 49XK19940216 are very likely the same cruise, same leg but
different sections.
They only crossover with themselves and with 49XK19960617

Analysis of beta version of GLODAP in preparation of the Bremen 2014 workshop
showed that
all three nutrients were consistent over the three cruises (with the PO4
correction of 1.03
for the two 1994 cruises applied).

The 1996 cruise has crossovers with several other cruises, and nutrients are
clearly too
low on this. Notably when compared with 32MW19890206, which is good.

This could be related to a unit conversion issue, and at the Bremen workshop we
hence decided that all nutrients of these cruises should be
adjusted by 1.025
to bring them into consistency with the 32MW19890206 cruise.

GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.02

Posted by svheuven@gmail.com on 2014-06-16 15:50:46 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49XK19960617 - phosphate

49XK19940212 and 49XK19940216 are very likely the same cruise, same leg but
different sections.
They only crossover with themselves and with 49XK19960617

Analysis of beta version of GLODAP in preparation of the Bremen 2014 workshop
showed that
all three nutrients were consistent among the three cruises (with the PO4
correction of 1.03
for the two 1994 crusies applied).

The 1996 cruise has crossovers with several other cruises, and nutrients are
clearly too
low on this. Notably when compared with 32MW19890206, which is good.

This could be related to a unit conversion issue, and at the Bremen workshop we
hence decided that all nutrients of these cruises should be adjusted by 1.025
to bring them into consistency with the 32MW19890206 cruise.

Autogenerated comment - silicate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.01. One very good
xover, with 32MW19890206, shows this cruise to be 3% too low. However, after
applying precorrections of +1% and -1% to JPN and US cruises respectively, it's
only 1% too low. 32MW is very accuracte, so I opt to increase 49XK19960617 by
that residual 1% (for a total adjustment of 2%, counting that pre-adjustment).
Listed adjustment for SIL for this cruise additionally contains a pre-adjustment
of +1% (default for all Japanese Pacific SIL data).

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:6; 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.
