- wind-driven coastal upwelling and downwelling
- current instabilities and eddy interactions
- internal tides (three-dimensional motions of the stratified ocean forced by large scale astronomical tides)
- River plumes (in particular, the Columbia River plume)
- Currents along the beaches (forced by energy of breaking waves).
- Satellite altimetry (sea surface height)
- Sea surface temperature from a number of sensors
- Surface currents remotely measured by coastally-based high-frequency radars
- Vertical sections of temperature and salinity from autonomous underwater vehicles (gliders)
- Moored velocities
Our group has utilized comprehensive computer models to understand processes driving ocean dynamics (including material and heat transports) on coastal and regional scales. In particular, our research has been focused on:
We also do research on data assimilation, which is a set of mathematical methods to combine ocean models and available observations, to obtain the improved estimate of the ocean state and forcing. Our efforts in this direction have resulted in development of the real-time coastal ocean forecast model off Oregon (US west coast) that can be utilized for search and rescue, environmental hazard response, navigation, fisheries, etc. Data utilized have included:

- 02/06/2017A high-resolution US West Coast regional ocean circulation model has been developed and utilized to study seasonal and interannual variability in oceanic properties along the continental slope. In particular, in the annual cycle of the depth of a subsurface density level over the slope, we find a south-to-north propagating pattern with a characteristic speed of about 0.5 m/s. The annual cycle in the temperature sampled on the same surface is indicative of the poleward transport by the undercurrent. Anomalies from the seasonal cycle, on the same density surface, show deepening in 2014 all along the US coast, forced by the conditions much farther to the south, at 24N. The manuscript providing details of these analyses has been submitted to J. Geophys. Res. (The draft can be found here)
