Sampling depths are displayed as original pressure readings at the time of collection (PRES) and recalculated to meters (depth) using CTD temperature and density. Dissolved inorganic nutrients (Nitrate, Nitrite, Phosphate, Silicate), pigment content (ChlA, Phaeo), particulate organic C and N (POC, PN) and Winkler titrations of dissolved oxygen (DOW), are shown where samples have been collected and depths without sample collections are denominated ‘not a number’ (NaN). For brevity, columns with quality control (QC) flags, associated with each measured parameter (parameter_SEADATANET_QC) are not included in this overview.
