33MW19910711 - c13

Becker et al. 2016:
Cruise 33MW19910711 extends into the South Atlantic, and its crossover with
33MW19930704.1 shows no need for an adjustment.

Posted by nlange@geomar.de on 2018-09-05 17:40:39 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

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 - oxygen

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 1.00. Cruise may be
biased very slightly high (~0.5%), but not clearly enough so to warrant
adjustment

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Few data, very noisy.
The only really usefull xover is against 33RO20050111, which is repeat hydro,
and is ~4% below this on. Applying inversion suggestion doesn't really help
though. Comparison against WOA2009 suggests occasionally 20% low. Scrap.

Autogenerated comment - nitrate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Profiles are very
scattered, noisy, hard to assess. Has no PO4 either. Does not seem appreciably
offset from RO332005, which is excellent for NO3, but spread is unacceptable.

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

profiles (up to 40 umolkg).

33MW19910711 - alkalinity

Mean offset with 3 cruises: -17.8
Inversion suggests +9
However, several x-overs show large spreading, much more than for other cruises.
I suggest to flag this cruise as bad.

33MW19910711 - tco2

Mean offset with 6 cruises: -2.1
Inversion suggests insignificant 0.1
I suggest NO adjustment in agreement with GLODAPv1

Posted by mario.hoppema@awi.de on 2012-12-13 16:33:04 UTC for data product: GLODAPv2

33MW19910711 - oxygen

The inversion suggest a correction of 0.9974 based on 9 xovers with a MO of
1.002. No correction is recommended.

Posted by are.olsen@uib.no on 2012-09-17 13:34:22 UTC for data product: GLODAPv2

33MW19910711 - silicate

The inversion suggest a correction of 1.0315 and mean offset is 0.967 and it
looks a bit low, for instance compared to (2100) 316N19940403 and (1100)
35A319930102, and I recommend that the data are adjusted using a factor of 1.03.
Not done in GLODAP.

Posted by are.olsen@uib.no on 2012-09-13 20:43:18 UTC for data product: GLODAPv2

33MW19910711 - nitrate

Suggested correction is 1.0297, mean offset is 0.973.
This appears low, we recommend adjust using 1.03.

33MW19910711 - salinity

The inversion suggest a correction of 1.79 ppm, based on 8 crossovers with a
mean offset of -0.672 ppm, do not adjust.
