Research interests

The coastal zone is one of the most valuable and vulnerable areas of the Earth’s habitats. The increase of human population and disturbance in coastal zones have altered the biogeochemical cycles of Carbon (C), Nitrogen (N) and Phosphorus (P) in coastal waters, mainly through river discharge, submarine ground water and atmospheric deposition, thus modifying the fluxes of these essential elements in terms of magnitude and composition. Moreover, compared to open waters, coastal area dynamics is less predictable and more difficult to interpret due to a number of processes acting on very different spatial and temporal scales.
My research activity involves a multi-scale approach, with increasing levels of complexity, to study of the C, N and P dynamics in different coastal areas. The aim of this work is to identify common patterns and/or peculiarities among different environments and to elucidate the interactions between nutrient dynamics, physical forcings and microbial communities.
The research is structured in two different objectives, which can be summarized as:

  • Long term observations of C, N and P at the LTER-MareChiara station.
  • In situ observations of abiotic parameters in different environmental ecosystems.

Main practical outcomes include: 1) definition of indicators for water quality; 2) information on global climatic dynamics useful for modelling and forecasting the future functioning scenarios of oceans.
