Ruth C. Musgrave Massachusetts Institute of Technology 77 Massachusetts Avenue, Building 3-361b Cambridge, MA 02139, USA. Email: rmusg@mit.edu Web: http://www.mit.edu/ rmusg/ Citizenships: British & Australian VISA: US J1 Research interests As a sea-going physical oceanographer I combine observational data, numerical models and theory to try to understand processes in the ocean. I am interested in the energy pathways that connect large scale forcing to small scale dissipation. In particular, I study the physical processes that form these pathways, and their influence on regional and global scales. My work focusses on a number of different areas, including tidally driven mixing, topographically trapped internal waves, quasi-steady flow-topography interactions, and high latitude physics.
