58GS20090528 - alkalinity
Alk on this cruise is consistently high. The offsets are constant with depth
and there does not appear to be a temporal trend. There are many outliers here
and at the GLODAP2 meeting after the CarboChange annual meeting in Norwich it
was decided to redo the primary QC for alkalinity on this cruise.

58GS20090528 - phosphate
There seems to be a temporal trend: the older reference cruises give larger
offsets than the newer ones. There is a very large offset with 58GS20030922 but
this could be due to the eddy/gyre observed on the 2003 cruise.

58GS20090528 - silicate
There is a clear temporal trend: until 1999 the older reference cruises give
higher offsets while after 1999 the offsets increase again for the newer
reference cruises. Silicate on this cruise is consistently very high. The
offsets increase with depth (i.e. the deep waters have greater offsets than the
shallower intermediate water). Even with the temporal trend an adjustment is
needed here - the question is how large. Based on the five most recent
reference cruises I give this an adjustment of 0.95.

58GS20090528 - cfc12
As for 58GS20060721 this is tricky since the evolution in the Greenland Sea
(where most of the covers are) makes it more likely for deeper convection, and
hence increased CFC concentrations would be more or less expected. In addition
there were several analytical issues during the cruise, although less for CFC12.
The surface saturation is ~110% and the xovers show only small offsets with
recent cruises (and actually overall), except for the 58GS2003 cruise, which had
a strong eddy, significantly affecting the deep water concentrations. From this
I do not recommend any adjustment for CFC12.

58GS20090528 - cfc11
There were some analytical problems with CFC11 during the cruise, and this CFC
was only measured during the first parts of the cruise. The data in the
Greenland Sea are believed to be ok, but the overall quality is uncertain. The
surface saturation is high (~120%), similar to the 2006 cruise, but inconsistent
with CFC12 (which were almost 10% lower). The xovers with recent are not
consistent, but the comparison with the 2002 Knorr cruise indicate a high
offset. Taking this, and the inconsistency with CFC12 I recommend to adjust the
CFC11 data with 0.90. But again, the overall quality is somewhat questionable,
which can be seen in the CFC12-CFC11 plot found under CFC12.
