PhD project title:

Ocean acidification effects on planktic calcifiers and biological pump efficiency.

PhD project description:

My research focuses on the seasonal distribution of marine calcifiers and their contribution to carbon standing stocks and export production in the Northern Barents Sea. In particular, I am studying planktic foraminfiera, shelled pteropods and coccolithophores, which are located at the base of the food web and have been reported to have an important role on the carbon cycle by exporting inorganic and organic carbon from the surface, where they inhabit, to the seabed, when they die and sink. I am also particularly interested on studying them on the fossil record (short sediment cores) and use them as proxies to reconstruct the environmental conditions from the last 12000 years.

Start date: May 2019
Planned submission date: March 2023
