title: Simultaneous measurements of oxygen and carbon dioxide fluxes to assess productivity in phytoplankton cultures.
abstract: We validate a method that simultaneously measures O(2) and CO(2) fluxes by sampling headspace air in phytoplankton cultures. Fluxes were strongly correlated to traditional productivity measures, except for a taxon with unique C metabolism. The method provides accurate, real-time, non-destructive measurements and is recommended for laboratory studies of phytoplankton physiology.
