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:6; 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 1.015. This adjusts cruise
onto the gradually undulating trend. Previous adjustment of 1.04 would adjust to
mean level of all cruises between 1995 and 2010, which is not appropriate in
this variable region.

Autogenerated comment - silicate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.00. Variable region, and I
don't see strong offsets with cruises in nearby years

Autogenerated comment - phosphate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.04. Mean xover is -4±5%,
inversion suggestion is +4.3%.

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. Large scatter
between profiles, this is only borderline acceptable.

Autogenerated comment - alkalinity

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : Maintain 0. Cruise is region of
strong trends, and seems to fall approximately on the trend line. 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.

Autogenerated comment - salinity

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 0. Cruise in highly variable
region. Matches quite well with its contemporaries.

18HU20040515 - cfc113

CFC-113 of this crusie is relatively high compared to the other Hudson cruises;
could be adjusted downward by 10%.

18HU20040515 - tco2

The xover analysis show an offset of 4 but this is due to a real trend. Do not
adjust

18HU20040515 - oxygen

Oxygen on this cruise has a clear and consistent offset. The offsets are
constant with depth

18HU20040515 - silicate

Silicate on this cruise is consistently high and there is no evident temporal
trend

18HU20040515 - general

All xovers are below 2500m
There are not enough bottle salinities so use ctdsal as salinity
