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

49NZ20170208 - silicate

3 crossovers showing offsets on the upper 2% limit. The MLR analysis does not
support such a strong bias. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:53:36 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - salinity

Only 4 crossovers (1 recent) but all indicate accurate data. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:53:20 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - phosphate

All three types of analyses - crossovers (3), MLR and depth comparison indicate
acceptable data. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:53:09 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - nitrate

All three types of analyses - crossovers (3), MLR and depth comparison indicate
accurate data. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:52:53 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - oxygen

All three types of analyses - crossovers (3), MLR and depth comparison indicate
accurate data. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:52:39 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - alkalinity

Only one crossover but with offset in acceptable range. The MLR analyses also
indicate acceptable data but rather on the other side of the limit (offset of
roughly -3). Maintain

Posted by nlange@geomar.de on 2018-09-19 16:52:21 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208 - tco2

1 crossover - clearly within range - and a very small offset resulting from a
MLR analysis indicate very accurate data. Maintain.

Posted by nlange@geomar.de on 2018-09-19 16:52:02 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

49NZ20170208

No more than three crossovers (only 1 "recent" one) per parameter does not
enable 2nd QC. Tracer data is present but not finalized at this stage.
