49UP20170623 - ph
This crs analysis nicely shows that there might have been a trend towards lower
values in the past decade. However, this cruise (as many other of the new
update) does not follow this trend or it is not a trend but rather coincidence
of the reference data. In any case no adjustment can be recommended based upon
the crs analysis. The interconsistency check supports this finding with a very
good match (0.0010 +/- 0.0121).

49UP20170623 - phosphate
Given the nice precision of the data (and reference data) a small adjustment can
be proposed. It seems that the cruise data is 1% low. This offset is clearly
present in the great majority (roughly 66%) of the crs and is consistent with
depth. Only the very large number (39) justifies such a small adjustment in this
region. Adjust upward.

The data might be a bit high but the offset is not as striking as for example
for phosphate. Not enough evidence for an adjustment within the limits.

Seen on ist own, concentrations seem a bit high. However, if the very good fit
with CFC_11 is taken into account the impression of natural oversaturation

49UP20170623 - cfc12
Seen on ist own, concentrations seem a bit high. However, if the very good fit
with CFC_11 is taken into account the impression of natural oversaturation
strikes out. Accurate data. Maintain.

49UP20170623 - ph
This crs analysis nicely shows that there might have been a trend towards lower
values in the past decade. However, this cruise (as many other of the new
update) does not follow this trend or it is not a trend but rather coincidence
of the reference data. In any case no adjustment can be recommended based upon
the crs analysis. The interconsistency check supports this finding with a very
good match (0.0010 +/- 0.0121).

49UP20170623 - silicate
The data might be a bit high but the offset is not as striking as for example
for phosphate. Not enough evidence for an adjustment within the limits.
Maintain.

49UP20170623 - phosphate
Given the nice precision of the data (and reference data) a small adjustment can
be proposed. It seems that the cruise data is 1% low. This offset is clearly
present in the great majority (roughly 66%) of the crs and is consistent with
depth. Only the very large number (39) justifies such a small adjustment in this
region. Adjust upward.
