Seasonally Resolved Ecophysiology of Arctic Marine Phytoplankton in Kongsfjorden

Phytoplankton are key drivers of complex interactions between biology, geochemistry, and climate. Temperature plays an important role in phytoplankton metabolism which has direct effects on biogeochemical cycling under global warming. The Arctic is warming more than twice as fast as the global average, but there are major differences seasonally. Kongsfjorden has been the site of long-term monitoring for many years, and despite this, the autumn remains a largely uncharacterized season for phytoplankton physiology especially in relation to climate warming. The lack of in-situ data hinders our judgment on how seasonally changing physiological plasticity relates to stress susceptibility, productivity, and ecosystem services.
