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:3; no CTD salinity data. Setting CTD salinity offset to -999,
QC flag removed.
Oxygen action ID:3; no CTD oxygen data. Setting CTD oxygen offset to -999, QC
flag removed.

Autogenerated comment - alkalinity

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Unacceptable scatter in
profiles (up to 40 umolkg). Note that most Hudson TA data are of mediocre
quality at best. There appear to be occasional calibration breaks between the
southern shelfbreak leg and the main Labrador Sea leg, and data are generally
exceedingly noisy.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:

region. Matches quite well with its contemporaries.

18HU19980622 - cfc12

CFC-12 saturation is very high (~120%), much larger than the CFC-11 saturation.
The property-property plot of CFC-11 and CFC-12 also indicates high CFC-12
compared to CFC-11. The x-overs, however, do not show generally larger results
for CFC-12 compared with CFC-11. Nevertheless, a reduction of CFC-12 by 5% is
recommended.

18HU19980622 - tco2

Mean offset with two cruises: -6.5
x-overs with 18HU19950607 316N19810821 which are older cruises would not be
expected to be negative. Seems like this cruise is somewhat too low.
Inversion suggests correction of +6.3
I suggest to adjust the minimum of +4

18HU19980622 - alkalinity

Mean offset with only two cruises: -2.7 (but one with -20 and the other with
+25).
Not enough data to make a decision, as this is also in the Labrador Sea with
much variability. Therefore -888

18HU19980622 - phosphate

Earlier decision of giving no adjustment is confirmed by new inversion for
phosphate in the Atlantic with 10 core cruises assigned.

18HU19980622 - oxygen

The inversion suggest a correction of 1.006. Mean offset is 1.006, this is based
on three crossovers. Similar in values to (300) 18HU19950607,(1.0047) & (200)
06MT19941115. Do not adjust.

18HU19980622 - silicate

Inversion suggest correction of 1.023 and mean offset is 0.992. Based on three
crossovers, all in the Lab Sea. This may be natural variations, no adjustment
can be recommended.

18HU19980622 - phosphate

Suggested correction was 0.9367, based on three offsets, with mean value 1.018.
The data appear a bit noisy, confirmed by high covariance of suggested
correction. Highest of all cruises. The data appear too noisy to make decision,
that combined with the fact that this is a Lab Sea Cruise. No adjustment
recommended. Not done in GLODAP.

18HU19980622 - nitrate

Suggested correction was 1.0046. This is based on on three offsets with mean
value 0.968!. Cruise took place in Lab Sea. No adjustment can be suggested.

18HU19980622 - salinity

The inversion suggest a correction of -3.06 ppm based on 3 crossovers with a
mean offset of 0.376 ppm. Do not adjust.
