Comment:
Data from this cruise has been calibrated together with the data from the previous cruise M92 which used the same CTD sensors. Oxygen has been calibrated by combining conventional Winkler titrations from M92 and M93 and data from a Unisense Stox sensor that is capable of measuring very low oxygen values.. Oxygen values below 0 come either from very strong vertical gradient which results in an overshoot by a filter of the manufacturer, or are within the noise level of the instrument of about 1 mumol/kg. Such values hould be regarded as very very close to 0. Conductivity/Salinity measurements near the surface frequently suffered from biological matter. Use near surface values with caution.
Sound speed and pinger depth correction unkown. Use with care.
Fluorescence and Turbidity data still contain deck offsets. Use with caution
