Stations:	[1-last]
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

35TH20080825 - cfc12

Surface saturation levels are centered around 100% with the vast majority
showing no deviations larger than 5%. Maintain.

Posted by nlange@geomar.de on 2020-02-19 18:38:08 UTC for data product: GLODAPv2.2020, v2.2021

35TH20080825 - ph

More than 90% of the crossovers are within the 10% range. The interconsistency
check (crs with calculated DIC) further supports good accuracy. Maintain.

Posted by nlange@geomar.de on 2020-02-19 18:37:43 UTC for data product: GLODAPv2.2020, v2.2021

35TH20080825 - salinity

Temporal trend is visible making the crs analysisi less straight forward.
Nevertheless cruises around 2008 show a good match. Maintain.

Posted by nlange@geomar.de on 2020-02-19 18:37:29 UTC for data product: GLODAPv2.2020, v2.2021

35TH20080825 - oxygen

Crossovers indicate too high concentrations (e.g. 18HU20080520!). However for a
2% adjustment the evidence is not strong enough especially given that 18HU2008
might be too low by 1%. Maintain with doubts.

Posted by nlange@geomar.de on 2020-02-19 18:37:14 UTC for data product: GLODAPv2.2020, v2.2021

35TH20080825 - alkalinity

Given the region the large uncertainties are common. Further, the vast majority
(roughly 95%) of crs have an offset within the range. Maintain.
