Comment(s)
I am interested in the environmental problem of ocean acidification, the associated changes in the chemical balances of the CO2 system in seawater and the potential effects on the development and fitness of specific marine organisms. To this end my PhD research involved mainly observational data. I have characterized the spatial and temporal changes in the parameters of the CO2 system in the subtropical North Atlantic, from instrumental measurements performed along two transAtlantic hydrographic sections, with a special focus on pH and saturation states, in addition to classical studies on the penetration of anthropogenic carbon in the ocean. I am also interested in coccolithophores and other planktonic species, and on its fate in the face of a global change, particularly to understand possible induced changes in CaCO3 fluxes in the ocean by means of the effects of the observed and ongoing changes in the parameters of the CO2 system in seawater on their physiology and all the way up to its ecology. I am really curious about the potential derived impacts of ocean acidification on organisms with important roles in the carbon and nutrient cycling and in the trophic chain, and more generally on the oceanic carbonate and biological carbon pumps, through changes in the CaCO3 production and dissolution.
