The selected Calculated Carbon Parameter has been dismissed in October 2017! Legacy values will be exported as is and displayed in red with subscript "c", e.g. -0.123456_c! No data available? 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

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:5; CTD salinity data good, setting CTD salinity offset and QC
flag to bottle values.
Oxygen action ID:5; CTD oxygen data good, setting CTD oxygen offset and QC flag
to bottle values.

Autogenerated comment - oxygen

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.01. Very high precision,
very sharp xovers. Cruise is clearly 1.0-1.5% too low, as is previous leg
33AT20120324.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.00. Unbiased according to
inversion, and also a perfect match to OC1983 and 316N1997/2003. I do not see
the 2-3% bias that Siv mentions.

Autogenerated comment - phosphate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 1.00. Inversion is
confident this cruise is biased almost 1% high, and thus needs 0.99. However,
given the shakiness of N-Atl PO4 and our threshold of 2%, this stays at *1.00

Autogenerated comment - nitrate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 1.00. Not investigated in
detail, but inversion thinks <1%, and existing adjustment is 0%

33AT20120419 - ctd_oxygen

Same result as for oxygen

33AT20120419 - oxygen

There is a consistent offset of 1% which is also seen in ctdoxy. Adjust both

33AT20120419 - silicate

This is a bit tricky since for some of the xovers the weighted mean offset is
artificially high (see figures). Still, when comparing to the direct repeats of
the line in 1983 and 2003 there is a consistent offset of ~1.03 so I'm
suggesting an adjustment of 0.98

Posted by siv.lauvset@uib.no on 2013-06-21 13:02:19 UTC for data product: GLODAPv2

33AT20120419 - alkalinity

Large offset with same GEOSECS cruise as tco2. I'm ignoring that result.

33AT20120419 - ctd_salinity

same as for salinity

Posted by siv.lauvset@uib.no on 2013-06-21 12:59:13 UTC for data product: GLODAPv2

33AT20120419 - tco2

There is one very large offset with a GEOSECS cruise. This is ignored since the
GEOSECS cruises are not adjusted (and most likely offset themselves)

33AT20120419 - tco2

double

33AT20120419 - salinity

There is one very large offset (with reference cruise 06MT19990711) but these
overlap with only 4 stations on the shelf in the north and the divergence is
only down to -2000m. I'm ignoring this in the adjustment determination.
Otherwise all offsets are within limits.
