Andrea Ogston was drawn to the study of sediment transport while driving past mudflats, walking along beaches with crashing waves, and sailing across river plumes laden with mud. As an oceanographer, she has focused her research on those interactions between geological and physical oceanography of the coastal ocean, using observational techniques to study the dispersal of sediment from the rivers to the deep sea. As part of a project funded by the National Science Foundation, she has also followed closely the dismantling of the dams on the Elwha River, studying what happens when more than a century’s worth of riverine sediment is suddenly released, and makes its way to the ocean for the first time.
