Hanna explores major themes of physical oceanography including dynamics of ocean currents on various spatial scales, temporal variability of these currents, distribution of heat, salt and other water properties and their transport through the ocean basins, and interaction between open oceans and marginal seas. One of her main research topics focuses on the western boundary current system in the North Pacific, based on field observation using research vessels and data analysis using statistical tools.
