My interests as a physical oceanographer include numerical and observational modeling of circulation and water quality in the ocean and Puget Sound. Beginning in June of 1998, I have been a Co-chief Scientist for the PRISM Semi-Annual Hydrographic Survey of Puget Sound through the School of Oceanography.
With numerical and theoretical modeling, my research focuses on seasonal and interannual variablility of estuarine and fjord circulation, population connectivity in estuarine environments, and marine renewable energy sources.

Seasonal variability of the exchange circulation in Hood Canal, Washington is studied using a three-dimensional hydrodynamic model of the circulation forced with climatological seasonal river discharge and salinity outside the mouth of the canal. River discharge and salinity are varied both individually as well as together to study their relative importance in generating variability. Deep inflow into the canal has a maximum transport in August – Septepmer and a minimum in January. Most of the variability still exists when the river discharge is held constant and only the external salinity is varied; with only the river varying, the maximum transport occurs in January, the minimum in September, and the amplitude of the variability is much reduced. There are significant seasonal changes in the vertical structure of the inflow. The peak inflow during August – September reaches deep, coinciding with the dense water intrusion. In November the inflow core rises to mid-depth and stays there until the next June, while the near-bottom layer becomes almost stagnant. This switch between two- and two-and-half-layer circulation agrees with the observed rising of the sequestered oxygen minimum layer to just below the pycnocline in September, and the subsequent mid-depth ventilation of the canal in winter and the spring.
While adult brown rockfish don't move much from their rocky terrain, their offspring do, and no one really knows what becomes of the baby rockfish once they're hatched. Strong currents may have a significant impact on the dispersal of these baby rockfish, sending them out of Marine Protected Areas and into the unknown. Scientists would like to know whether they make it to the next protected area or not, which would increase biodiversity and therefore, the overal health of these protected locations. To estimate rockfish dispersal, scientists have been refering to models of Puget Sound and oceanographic drifters.

Together with Snohomish County PUD, Dr. Kawase explores possibilities for capturing the renewable energy generated by tidal currents. Several sites in Puget Sound are under investigation: Spieden Channel, San Juan Channel, Guemes Channel, Decption Pass, Admiralty Inlet, Agate Passage and Rich Passage. These sites could potentially contribute, on average, over 100 MW if they get developed.
