Principal thermocline pathways in the Atlantic Ocean
Speaker: Josep Lluís Pelegrí, Institut de Ciències del Mar de Barcelona (CSIC).
The objective of this talk is to give a broad picture of the thermocline circulation in the Atlantic Ocean, pointing at the major pathways that have already been identified and those that are yet poorly known. For this purpose, I will provide a summary of the subantarctic waters entering the South Atlantic Ocean, the transfer of subantarctic and South-Atlantic waters to the tropical ocean, the equatorial jets and tropical/subtropical cells, the subtropical thermocline circulation and shadow zones in both hemispheres, and the quite different character in the fate of western boundary currents in the South and North Atlantic Oceans.
Seminario: Effects of CO2 and long day length on primary productivity in the Arctic Ocean: a perspective on climate change

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).
Summary: 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!
