Research Interests

Main research interests include the use of satellite observations in combination with in situ observations or hydrodynamic models, to study physical oceanographic processes. The physical processes include detection of Greenland-Scotland ridge overflow, North Atlantic mixed layer deepening and sea level in the North Sea. Currently, I am working to validate satellite SST data and on a high resolution multiplatform 3-D Optimal Interpolation (OI) product. Observational network assessment and design is the topic of on-going research.
