33RO20161119 - ph
Except for one doubtful crossover (316N2005), all crossovers show a negative
offset. The magnitude of the offset varies quite strongly though. However, the
weighted mean offset of the crossovers is also supported by the result of the
interconsistency check (type 2). The check indicates slightly too low (offset
-0.0044) pH values. Adjust accordingly upward.

All offsets are clearly within the acceptable range. Offsets indicating both,
too high and too low concentrations, exist. Maintain.

The N/S gradient is not present in other variables, notable nutrients.
Also 1st leg has an 2% offset.

This seems to be a case for split by station: This cruise had two legs (Easter
Island break). Redo for the two legs independently.
Even so it seems to be a N/S gradient in oxygen offset, with higher offset in
the south
Possibly flag the one outlier profile

The CTD Oxygen values were updated at CCHDO on Sep 21st, 2018.
https://cchdo.ucsd.edu/cruise/33RO20161119
The update now contains the final QC'd CTD Oxy as submitted by the data
generators in Aug 2017. The updated values are higher.

33RO20161119 - oxygen
Crossovers can be grouped into two categories:
Crossovers having crossover-stations in the southern ocean / oxygen rich zones:
--> 10% too low concentrations
Crossover not having a crossover-station in the southern ocean:
--> 2% low concentrations"
Hence, it is difficult to find one adjustment for the entire cruise. Adjust at
least 2% upward.

nice accuracy. Agreed upon in Seattle.

The N/S gradient is not present in other variables, notable nutrients.
Also 1st leg has an 2% offset.
Rik is checking with PI. In the meantime flag -777

This seems to be a case for split by station: This cruise had two legs (Easter
Island break). Redo for the two legs independently.
Even so it seems to be a N/S gradient in oxygen offset, with higher offset in
the south
Possibly flag the one outlier profile

The CTD Oxygen values were updated at CCHDO on Sep 21st, 2018.
https://cchdo.ucsd.edu/cruise/33RO20161119
The update now contains the final QC'd CTD Oxy as submitted by the data
generators in Aug 2017. The updated values are higher.

33RO20161119 - ph
Except for one doubtful crossover (316N2005), all crossovers show a negative
offset. The magnitude of the offset varies quite strongly though. However, the
weighted mean offset of the crossovers is also supported by the result of the
interconsistency check (type 2). The check indicates slightly too low (offset
-0.0044) pH values. Adjust accordingly upward.

33RO20161119 - oxygen
Crossovers can be grouped into two categories:
Crossovers having crossover-stations in the southern ocean / oxygen rich zones:
--> 10% too low concentrations
Crossover not having a crossover-station in the southern ocean:
--> 2% low concentrations"
Hence, it is difficult to find one adjustment for the entire cruise. Adjust at
least 2% upward.
