This dataset contains results from the Second International BIOMASS Experiment II (SIBEX II) cruise of the Nella Dan, taken in January 1985. This cruise was the fourth cruise in a series of six. Phytoplankton samples were taken off Antarctica in the Australian sector (Mawson to Davis region) and Prydz Bay in January 1985. Taxonomic identity, distribution and abundance data were obtained, together with an extensive range of pigment analysis, using high performance liquid chromatography (HPLC). Over 60 pigments were analysed (only the major ones are listed here). The major phytoplankton investigated were diatoms, dinoflagellates and flagellates. This dataset is a subset of the full cruise. An excel spreadsheet containing the full pigment analysis obtained from the cruise is available for download from the URL given below. The spreadsheet is a digital version of the data presented in ANARE Research Notes 58, which was a report written based on this dataset. There are three worksheets to the spreadsheet: 1) Abbrev. - details the abbreviations used in worksheets 2 and 3. 2) Table 3 - Table 3 data entered from ANARE Research Notes 58. 3) Transposed Table 3 - The same data as worksheet 2, but arranged differently. A pdf copy of ANARE Research Notes 58 is also available for download at the URL given below. A paper written in 2006 about pigments in microalgae, which provides some up-to-date explanations about pigmentation, is also available for download, but owing to copyright restrictions, is only available for download by Australian Antarctic Division personnel. The fields in this dataset are: Date Time (GMT) Latitude Longitude Depth (metres) Pigment concentration (nanograms per litre) chlorophyllide a chlorophyll c methyl chlorophyllide a phaeophorbide a peridinin 19'-butanoyloxyfucoxanthin fucoxanthin 19'-hexanoyloxyfucoxanthin Neoxanthin Prasinoxanthin Violaxanthin Diadinoxanthin Alloxanthin diatoxanthin Zeaxanthin Canthaxanthin Unknown Chlorophyll b Chlorophyll a allomer Chlorophyll a Chlorophyll a epimer Phaeophytin a derivative Phaeophytin b Phaeophytin a Chlorophyll a total % Degradation Pigment total This work was completed as part of ASAC project 40 (ASAC_40).
