Andrea Ogston’s research program explores the modern sedimentary processes that shape and form coastal environments. 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. She emphasizes tidal, seasonal, interannual variability in sedimentary systems and has delved into a range of environments from tidally influenced river channels and associated intertidal muddy mangrove forests to submarine canyons on the continental slope where high-concentration, gravity-driven flows episodicly race downslope. Her research field sites are located both close to home (e.g. evaluating marine impacts of dam removal on the Elwha River, WA) and far afield (e.g., investigating processes that shape the morphology of large tropical deltas including the Mekong and Ayeyarwady).
