Modified original parameter names to conform with BCO-DMO naming conventions The accompanying value is the detection limit for the technique or zero if that value is unknown.ħ = missing = Bottle didn't trip or sample wasn't taken. Best practice strongly recommends that the value before the change be preserved in the data or its accompanying metadata.Ħ = value below detection = The level of the measured phenomenon was too small to be quantified by the technique employed to measure it. This is the initial status for all data values entering the working archive.ġ = good value = Good quality data value that is not part of any identified malfunction and has been verified as consistent with real phenomena during the quality control process.Ģ = probably good value = Data value that is probably consistent with real phenomena but this is unconfirmed or data value forming part of a malfunction that is considered too small to affect the overall quality of the data object of which it is a part.ģ = probably bad value = Data value recognized as unusual during quality control that forms part of a feature that is probably inconsistent with real phenomena.Ĥ = bad value = An obviously erroneous data value.ĥ = changed value = Data value adjusted during quality control. Quality flags indicate values below detection limits and potentially erroneous data according to the codes below.Ġ = no quality control = No quality control procedures have been applied to the data value. Processing DescriptionĪsterisks next to some values for Fe and Mn denote samples where contamination is suspected. SAFe seawater intercalibration standards were analyzed at the beginning of each analysis day with iron concentrations of 0.96 ± 0.095 nmol L-1 for D2 and 0.125 ± 0.046 nmol L-1 for S1 (n = 10), which are within the reported ranges of 0.91 + 0.17 nmol L-1 and 0.097 + 0.043 nmol L-1 (Johnson et al. Iron and Manganese Analyses: Total dissolved iron and manganese concentrations were measured using inductively coupled plasma mass spectrometry (ICP-MS). Measurements were made using Eco-Chemie uAutolab-III systems connected to Metrohm 663 VA Stands with hanging mercury drop electrodes and Teflon sampling cups. Alpkem rapid flow analyzer (RFA) 300 components were used to measure silicic acid, nitrate+nitrite, and nitrite.Ĭobalt Analyses: Total dissolved and labile cobalt concentrations were determined using cathodic stripping voltammetry, previously described by Saito and Moffet (2001) and Saito et al. Nutrient Analyses: Technicon AutoAnalyzer II components were used to measure phophate and ammonium. (2012) for detailed information on acquisition and processing. Three transects were sampled using the Trace Metal Rosette (TMR) on the CoFeMUG cruise aboard R/V Knorr in 2007.
