The data reports the pigment concentrations and results of CHEMTAX analysis for 2 summer seasons in Antarctic. In 2008/09 three experiments in which 6 x 650 l minicosms (polythene tanks) were used to incubate natural microbial communities (less than 200 um diameter) at a range of CO2 concentrations while maintained at constant light, temperature and mixing. The communities were pumped from ice-fre

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.
