Dr Stefano Ciavatta is a Senior Scientist at the Plymouth Marine Laboratory (PML) and UK National Centre for Earth Observation (NCEO). He leads the Data Assimilation research and development of the “Marine Ecosystems Models and Prediction” (MEMP) Department at PML. Stefano has a PhD in Environmental Sciences, achieved at the University of Venice, Italy. He has more than 30 peer-reviewed publications on marine ecosystem analysis and modelling (see list of recent publications).

Stefano’s main scientific activities are the analysis of the regional and global carbon cycle and the prediction of indicators of marine ecosystem health and services (e.g. coastal eutrophication, ocean acidification and deoxygenation, and aquaculture sustainability) in a changing climate landscape. Stefano develops and applies biogeochemical data assimilation systems, to improve the simulations of global and regional marine models (e.g., NEMO-ERSEM and NEMO-MEDUSA). He applies data assimilation also with time-series models, to investigate the trend and seasonal cycle of marine biogeochemical data, and to understand changes in the plankton trophic dynamics. Stefano assimilates and analyses data from both remote sensing and in situ platforms (e.g. ocean-colour phytoplankton functional type and optical products from satellites, as well as nutrients, pH, oxygen from gliders, floats and moorings).

Other areas of research and application are the sensitivity/uncertainty analysis of marine system models, including pollutant bioaccumulation models, and the statistical analysis of monitoring data.
