Esporles, February 15, 2018.
Since pelagic and benthic ecosystems contribute largely to the primary productivity of the Arctic Ocean, the experimental effect of increased CO2 during episodes of CO2 limitation has been researched in her thesis along with the effect of long day length, characteristic of Arctic summers, due to the likely migration of subarctic marine vegetation into an ice-free Arctic.
These effects have been evaluated on planktonic communities and benthic macrophytes in subarctic and Arctic ecosystems.
In parallel, the relationships between planktonic primary production rates estimated with three different methods (the O2 mass balance, the 18O method and the 14C method) have been addressed for the first time in the Arctic Ocean.
You are very welcome to come and look at her results and conclusions!
