The selected Calculated Carbon Parameter has been dismissed in October 2017! Legacy values will be exported as is and displayed in red with subscript "c", e.g. -0.123456_c! No data available? Insert -999 No suggestion for adjustment possible? Insert -888 To calibrate CTDsal use: CTDsal_calibrated = (CTDsal - CTDsal_intercept) / CTDsal_slope To calibrate CTDoxy use: CTDoxy_calibrated = (CTDoxy - CTDoxy_intercept) / CTDoxy_slope

320620151206

An additional MLR analysis based on GLODAPv2 has been carried out for all given
variables (for the most part following the method described in Jutterström et
al., 2010). Herefore only deep and approximate data (as for the crossover
analysis) has been used. For this cruise however its limited amount of data
deeper 1500m has capped the maximum number of samples per (dependent) variable
to 6 ... Thus, for no variable a robust result/offset could be gained.
Examplarily the corresponding results for silicate have been uploaded,
indicating a bias in the data - note that the strong differences in the
magnitude of the offsets do not permit any adjustment....

320620151206 - salinity

Based on 4 crossovers only - the results show a good agreement between the
crossovers, indicating slightly too low concentrations especially between 2000m
- 2500m. Nonetheless, not enough for an adjustment. Maintain.

320620151206 - oxygen

Based on 4 crossovers only - the results show a good agreement between each
other, indicating 0.5% too high concentrations. Nonetheless, not enough for such
a small adjustment. Maintain.
