Seawater carbonate chemistry and algal abundance, growth and flourometry data of a late summer suface sea ice community ...
Annual fast ice at Scott Base (Antarctica) in late summer contained a high biomass surface community of mixed phytoflagellates, dominated by the dinoflagellate, Polarella glacialis. At this time of the year, ice temperatures rise close to melting point and salinities drop to less than 20. At the sam...
