Pelagic and ice-associated microalgae under elevated light and pCO2: Contrasting physiological strategies in two Arctic diatoms

DOI

Laboratory experiment on acclimated physiological responses of the Arctic diatoms Thalassiosira hyalina and Melosira arctica towards elevated irradiance (50 vs 300 µmol photons m-2 s-1) and CO2 partial pressures (380 vs. 1000 μatm). Next to growth, elemental composition and biomass production, we assessed detailed photophysiological responses through fluorometry and gas-flux measurements, including respiration and carbon acquisition. Both algal cultures were isolated from the field within 2 years before the experiment, T.hyalina in Kongsjorden, Svalbard, and M.arctica in the Fram Strait close to Svalbard.
