  • The values of DIC, TA, and nutrients (silicate, phosphate, and nitrate) 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 KNOT data only.)
