Asterisks next to some values for Fe and Mn denote samples where contamination is suspected. Quality flags indicate values below detection limits and potentially erroneous data according to the codes below.

Quality Flag Codes:
0 = no quality control = No quality control procedures have been applied to the data value. This is the initial status for all data values entering the working archive.
1 = 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.
2 = 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.
3 = probably bad value = Data value recognized as unusual during quality control that forms part of a feature that is probably inconsistent with real phenomena.
4 = bad value = An obviously erroneous data value.
5 = changed value = Data value adjusted during quality control. Best practice strongly recommends that the value before the change be preserved in the data or its accompanying metadata.
6 = value below detection = The level of the measured phenomenon was too small to be quantified by the technique employed to measure it. The accompanying value is the detection limit for the technique or zero if that value is unknown.
7 = missing = Bottle didn't trip or sample wasn't taken.

BCO-DMO Processing Notes:
-Modified original parameter names to conform with BCO-DMO naming conventions;
-Missing values (blank) were replaced with 'nd' to indicate 'no data'.
History:
7 October 2009 - nutrients and preliminary Co data submitted to BCO-DMO; awaiting documentation from originating PI.
February 2010 - units for nutrient data confirmed to be micromolar; Cobalt measurements will be added in the future and are picomolar.
20 March 2013 - Co, Fe, Mn data submitted and joined to nutrients. Quality flags were also added by investigator.
