49UP20120307 - salinity
Even the "better" crs have std larger than the sepcified salinity range. A max
depth of 2027m and a max of three samples below 1500m per station is not enouth
for a robust crs analysis/2nd QC.

Only three sign crs of dubious quality due to the limited depth of the
cruise-in-question. Not enough for a 2nd QC.

49UP20120307 - ph
4 out of 6 crs offsets are within the range. All offsets are accompanied by
large std but (maybe) acceptable. The two Mirai cruises indicate a too low pH
value though. The interconsistency is ok but also accompanied by a large std
(0.0088 +/- 0.0179 ) and its quite striking that the interconsistency offset if
almost opposite to the crs results... No reliable conclusion possible....(?)

All crs offsets are clearly within the range. Robust 2nd QC - especially given
the few "deep" sampels! Maintain.

49UP20120307 - nitrate
Maintain.

49UP20120307 - salinity
Even the "better" crs have std larger than the sepcified salinity range. A max
depth of 2027m and a max of three samples below 1500m per station is not enouth
for a robust crs analysis/2nd QC.

49UP20120307 - ph
4 out of 6 crs offsets are within the range. All offsets are accompanied by
large std but (maybe) acceptable. The two Mirai cruises indicate a too low pH
value though. The interconsistency is ok but also accompanied by a large std
(0.0088 +/- 0.0179 ) and its quite striking that the interconsistency offset if
almost opposite to the crs results... No reliable conclusion possible....(?)

49UP20120307 - silicate
More than 95% of the crs offsets are within the range. Std are still acceptable.
All in all no doubts about accuracy (within 2% range). Maintain.

49UP20120307 - alkalinity
Only three sign crs of dubious quality due to the limited depth of the
cruise-in-question. Not enough for a 2nd QC. Note that concentrations seem
rather low….

49UP20120307 - phosphate
All crs offsets are clearly within the range. Robust 2nd QC - especially given
the few "deep" sampels! Maintain.
