Brief description
Size fractionated chlorophyll a data (total and less than 20 µm) analysed using high performance liquid chromatography (HPLC). Underway samples were taken using a seawater line in the oceanographic lab on RSV Aurora Australis (approx. depth 4 m). CTD samples were taken using Niskin bottles attached to a CTD rosette. Six depths were sampled per station, based on fluorescence profiles from the CTD. Two of the two of six samples always included both near-surface (approximately 10 m) and the depth of the chlorophyll maximum where applicable. HPLC analyses were conducted according to the method of Wright et al. (2010). Column chlorophylls (µg L-1) and integrated chlorophylls (mg m-2) are shown in two separate tabs within the Excel spreadsheet.Lineage
