GLODAPv2.2023 Adjustments

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

77DN20210725 - cfc12

Most upper sample likely to be already below sharp halocline - undersaturation
nothing to worry about. Maintain.

Posted by nlange@geomar.de on 2023-05-22 12:46:47 UTC for data product: GLODAPv2.2023

77DN20210725 - silicate

Additional MLR analyses and deep water averages compared to older 77DN cruises
in the area (Karl Adam Ulfsbo) would support an upward adjustment.

Posted by nlange@geomar.de on 2023-05-11 11:12:23 UTC for data product: GLODAPv2.2023

77DN20210725 - sf6

Undersaturated by about 10% - as is CFC12.

Posted by nlange@geomar.de on 2023-05-09 13:31:08 UTC for data product: GLODAPv2.2023

77DN20210725 - cfc12

Undersaturated by about 15% - as is SF6. Maintain.

Posted by nlange@geomar.de on 2023-05-09 13:30:59 UTC for data product: GLODAPv2.2023

77DN20210725 - ph

The crossover analysis indicates a trend which is not confirmed by this cruise.
Not enough info for a proper 2nd QC.

Posted by nlange@geomar.de on 2023-05-09 13:30:47 UTC for data product: GLODAPv2.2023

77DN20210725 - silicate

CANYON-B likely to be biased as it might be highly influenced by (bad) 06AQ1987…
Maintain with doubts.
