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

74DI20110520 - alkalinity

Alkalinity data have been sent back to the PI for primary QC. Will not be
included in GLODAPv2.2018 but possibly in future versions

Posted by siv.lauvset@uib.no on 2018-10-01 09:40:09 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74DI20110520 - oxygen

This is a very variable region and changes seen in the crossovers could be
natural changes/variabilities. We err on the side of caution and do not adjust

Posted by siv.lauvset@uib.no on 2018-10-01 09:39:31 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74DI20110520 - oxygen

The profiles look odd if compared to other cruises. Anyway, all crossovers
indicate too low concentrations. Adjust upward.
Note that the proposed adjustment is rather conservative.

Posted by nlange@geomar.de on 2018-06-15 10:23:46 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74DI20110520 - alkalinity

There is strong scattering in the data. The profiles ("shape") differ a lot
compared to other cruises. However, all crosssovers show consistently strong
negative offsets.
Adjust accordingly to the weighted mean offset of -9.35.

Posted by nlange@geomar.de on 2018-06-15 10:21:48 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74DI20110520 - tco2

Given the temporal trend, the data seems to be ok - it is rather too low (see
"nice" fit with RO2003). Maintain.

Posted by nlange@geomar.de on 2018-06-15 10:20:22 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74DI20110520 - salinity

Offsets show a lot of variability, further most standard deviations are large,
too.
Given this great uncertainity and the region itself no adjustment suggested,
ignoring the weighted mean offset (0.01).
