Short summary

Ecophysiological studies on Antarctic cryptophytes to assess whether climatic changes such as ocean acidification and enhanced stratification affect their growth in Antarctic coastal waters in the future are lacking so far. Our results reveal beneficial effects of ocean acidification in conjunction with enhanced irradiance on growth and photosynthesis of the Antarctic cyrptophyte Geminigera cryophila. Hence, cryptophytes such as G. cryophila may be potential winners of these climatic changes.
