・The values of TA and silicate have systematic errors among cruises, because the analytical methods used for these determinations, and the precision and standards for analysis varied slightly from cruise to cruise. The dataset posted here is "corrected" in a cruise. If you need the corrected data for systematic errors among cruises, please see "Hydrographic Data at Station K2 and KNOT". (Available data are station K2 and KNOT data only.)

・Data flags of FLUOR and XMISS are Unknown (flag1) because of lack of the calibration.
