Dataset: pigments_HPLC

Pigment concentrations were determined using standard peak integration procedures and entered into Microsoft Excel Spreadsheets for submission to BCO-DMO. Parameters reported were: Magnesium-2,4-divinyl phaeoporphyrin a5 monomethyl ester, chlorophyll c2, chlorophyll c1, peridinin, 19-primebutanoyloxyfucoxanthin, fucoxanthin, neoxanthin, prasinoxanthin, violaxanthin, 19-prime hexanoyloxyfucoxanthin, diadinoxanthin, cis_fucoxanthin, alloxanthin, diatoxanthin, zeaxanthin, lutein, crocoxanthin, divinyl chlorophyll a, chlorophyll a, carotene-alpha, carotene-beta, chlorophyll c3, chlorophyll b, pheophorbide a, pheophytin a, and antheraxanthin.

BCO-DMO Data Processing Note:
Station information including date and position were contributed with the data sets for all stations (except NBP0601 S06 and S20). PERL scripts were used to convert Excel files to plain text files prior to upload to BCO-DMO server. The NBP0608 HPLC data included the hydro station number (named cast in the original Excel file), but the NBP0601 data did not include the hydro station numbers.

Note that HPLC station number should not be confused with the hydrography station numbers. BCO-DMO created the sta_HPLC number from the HPLC sample_ID included in the original data file to allow grouping of HPLC data into full depth range profiles. It appears that for some stations, complete HPLC profiles were formed by combining samples from bottles fired during two successive hydro casts. For example, NBP0601 HPLC station S07, includes samples from bottles fired at depths between 200 and the surface, and bottles fired between the 'bottom' and 125. It is possible that the samples came from bottles fired on hydro stations 13 and 14, but the station positions are not identical. The original HPLC data file does not include enough information to match the HPLC stations definitively with the correct hydro stations.
