My research career has been focused on the role of dissolved organic matter (DOM) in the oceans, which is made up of myriads of compounds with half-lives ranging from minutes to tens of thousands of years. DOM plays a key role in global biogeochemical cycles and is sensitive to the warming, acidification, deoxygenation and fertilization that the oceans have been experiencing, especially since the mid-twentieth century.
I have paid special attention to the stoichiometric and optical characterization of the DOM and, more recently, to the molecular and isotopic characterization. There are three tools in which I support myself to study the role of DOM: observation, experimentation and modeling. I carry out a transdisciplinary research, combining physics, chemistry and microbiology, fostering synergy and internationalization.
The geographic location of the Marine Research Institute has allowed me to study the role of DOM in the western margin of the Iberian Peninsula as a general model of coastal upwelling system, carrying out a pioneering work in this field. In parallel, in the last decade I have given an increasing weight to the study of the deep ocean through collaboration in international research programs and participation in the circumnavigation "MALASPINA 2010" and the projects "HOTMIX" and " FLUXES" focused on the study of the carbon fluxes in the deep waters of the Mediterranean Sea and the area of the Cape Verde Front.
