Interaction between geological and physical oceanography of the coastal ocean; dispersal of sediment from river to deep sea, emphasizing high-concentration, gravity-driven flows; sediment transport processes in marine environments from surf zone to continental slope; instrument development.


Lake Chelan sits 335 meters above sea level and reaches a depth of nearly 450 meters. The northern end of the lake is fed by the Stehekin River, which has produced a delta that has prograded some four kilometers in the last 9000 years. In summer 2010 we completed bathymetric and sub-bottom surveys of the northern five kilometers of the lake.


The removal of the Elwha and Glines Canyon dams from the Elwha River in Washington, USA, resulted in the erosion and transport of over 10 million m3 of sediment from the former reservoirs and into the river during the first two years of the dam removal process. Approximately 90% of this sediment was transported through the Elwha River and to the coast at the Strait of Juan de …

Jun 15, 2021· Marine water quality is fundamentally important for all plants and animals that depend on the Salish Sea. It affects the amount of phytoplankton that are present in the surface water, which is critical because phytoplankton naturally take in and lock up large amounts of free carbon and release oxygen to the environment.
