Nature – Münzner et al. (2023): Carbon dioxide reduction by photosynthesis undetectable even during phytoplankton blooms in two lakes

While these CO₂ sources gained a lot of attention, processes that reduce the amount of CO₂ have been less studied. The authors therefore examined the CO₂ reduction capacity during times of phytoplankton blooms. They investigated partial pressure of CO₂ (pCO₂) in two lakes at times of blooms dominated by the cyanobacterium Gloeotrichia echinulata (Erken, Sweden) or by the nuisance alga Gonyostomum semen (Erssjön, Sweden) during two years.
