49UP20140728 - salinity
All but one offset (32MW1989) indicate slightly too low concentrations - the
agreement is very striking, see examplarily NZ200505. However, in some rare
cases the offsets seems to be at least less in depth, e.g. UP2010. Given this
doubt and that the absolute offset is within the acceptable range I suggest to
keep it as it is.

49UP20140728 - alkalinity
The variation of the offsets of the four crossovers is striking. It seems that
the offset is dependant on location - at least in so far that crossovers
restricted to regions close by PNG have a postive offset, see 49RY1994 (note
that it received a strong downward adjustment of -13 itself). The other two
crossovers with 32501993 and 49NZ2005 include much more stations and rather show
a negative offset. Since only one offset is larger 4, maintain.

Most offsets are within the 2% range. Larger offsets are only reached with UF
cruises (only "shallow" data), e.g. UF200401 or UP200706. Maintain.

49UP20140728 - ph
The analysis is rather difficult as only 4 crossovers are present. These have
strongly differing offsets. The highest crossover quality has 49NZ2005 (repeated
track), but it received a slight downward adjustment. The others only cross at
the very southern end near PNG or have quite scattery data themselves. However,
following the interconsistency check (type 2) a downward adjustment (-0.1) would
be needed which is more in line with the offsets from 49UP2010 and 49RY1994, and
hence the weighted mean. Adjust accordingly.

All but one station show a very accurate saturation ratio. Not the perfect fit
with CFC11 but that is probably a consequence of a slight CFC11 bias. Maintain.

Mabye slightly too high but not exceeding the 5% threshold limit. Further, too
few data to suggest an adjustment within the limits. Maintain.

49UP20140728 - ph
Following the discussion in Seattle and the new limits for pH we do not adjust
this cruise

49UP20140728 - tco2
Only four crossovers but all indicate a good accuracy. Maintain.

49UP20140728 - alkalinity
The variation of the offsets of the four crossovers is striking. It seems that
the offset is dependant on location - at least in so far that crossovers
restricted to regions close by PNG have a postive offset, see 49RY1994 (note
that it received a strong downward adjustment of -13 itself). The other two
crossovers with 32501993 and 49NZ2005 include much more stations and rather show
a negative offset. Since only one offset is larger 4, maintain.

49UP20140728 - nitrate
All offsets clearly fall within the acceptable range, even the ones with only
"shallow" comparisons. Accurate data, maintain.

49UP20140728 - phosphate
Most offsets are within the 2% range. Larger offsets are only reached with UF
cruises (only "shallow" data), e.g. UF200401 or UP200706. Maintain.

49UP20140728 - salinity
All but one offset (32MW1989) indicate slightly too low concentrations - the
agreement is very striking, see examplarily NZ200505. However, in some rare
cases the offsets seems to be at least less in depth, e.g. UP2010. Given this
doubt and that the absolute offset is within the acceptable range I suggest to
keep it as it is.

49UP20140728 - ph
The analysis is rather difficult as only 4 crossovers are present. These have
strongly differing offsets. The highest crossover quality has 49NZ2005 (repeated
track), but it received a slight downward adjustment. The others only cross at
the very southern end near PNG or have quite scattery data themselves. However,
following the interconsistency check (type 2) a downward adjustment (-0.1) would
be needed which is more in line with the offsets from 49UP2010 and 49RY1994, and
hence the weighted mean. Adjust accordingly.

49UP20140728 - cfc11
Mabye slightly too high but not exceeding the 5% threshold limit. Further, too
few data to suggest an adjustment within the limits. Maintain.

49UP20140728 - cfc12
All but one station show a very accurate saturation ratio. Not the perfect fit
with CFC11 but that is probably a consequence of a slight CFC11 bias. Maintain.
