Seawater carbonate chemistry and growth, elemental composition,biomass production, respiration and carbon acquisition of diatoms Thalassiosira hyalina and Melosira arctica ...
Sea ice retreat, changing stratification, and ocean acidification are fundamentally changing the light availability and physico-chemical conditions for primary producers in the Arctic Ocean. However, detailed studies on ecophysiological strategies and performance of key species in the pelagic and ic...
