325020210316 - tco2
All reasonable crossovers have at least an offset of 3umol/kg. The weighted mean
offset is also above the limit. Nevertheless, depth dependencies present.
Further note that anthropogenic carbon has been detected down to 3000m in this
region. For consistency, adjust downward by 4umol/kg (weighted mean offset
likely a bit too high due to some unreliable "bad" crossovers, e.g. 18HU ones).
CANYON_B comparison does not support this adjustment though as the offset is
much smaller (only 2umol/kg).

Might be 1% low, but standard deviations are too high to justify an adjustment.
CANYON_B comparison also indicate that concentrations might be a bit low, but
within limits. Maintain with doubts.

Might be a bit low, but only four non-calculated crossovers present of which two
have an offset within the limit. Maintain.

325020210316 - silicate
Very tricky analysis. Very high offsets should be ignored as based upon only the
very very deep (few) samples. Still multiple offsets indicate 2-3% too high data
- the offsets are depth dependent however. Some repeated lines do actually
indicate accurate data too. CANYON_B analysis shows a similar (uncertain) 2%
offset. Since 33AT2012 has also not been adjusted - follow that conclusion and
maintain with doubts.

325020210316 - silicate
Very tricky analysis. Very high offsets should be ignored as based upon only the
very very deep (few) samples. Still multiple offsets indicate 2-3% too high data
- the offsets are depth dependent however. Some repeated lines do actually
indicate accurate data too. CANYON_B analysis shows a similar (uncertain) 2%
offset. Since 33AT2012 has also not been adjusted - follow that conclusion and
maintain with doubts.

325020210420 - phosphate
Might be 1% low, but standard deviations are too high to justify an adjustment.
CANYON_B comparison also indicate that concentrations might be a bit low, but
within limits. Maintain with doubts.

325020210316 - tco2
All reasonable crossovers have at least an offset of 3umol/kg. The weighted mean
offset is also above the limit. Nevertheless, depth dependencies present.
Further note that anthropogenic carbon has been detected down to 3000m in this
region. For consistency, adjust downward by 4umol/kg (weighted mean offset
likely a bit too high due to some unreliable "bad" crossovers, e.g. 18HU ones).
CANYON_B comparison does not support this adjustment though as the offset is
much smaller (only 2umol/kg).
