• Speaker: Marina Sanz Martín, Ph.D student of the Global Change and Oceanography Department, will present her doctoral thesis titled ‘Effects of CO₂ and long day length on primary productivity in the Arctic Ocean: a perspective on climate change’ supervised by Carlos M. Duarte (King Abdullah University) and Paul F. Wassmann (The Arctic University of Norway).

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!
