Analyzing Dynamic Characteristics Of Internal Solitons Generated At The Columbia River Plume Front With Sar Images, David A. Jay, Jiayi Pan, R. D. Brodeur

Civil and Environmental Engineering Faculty Publications and Presentations

The Columbia River plume transports dissolved and particulate load, phyto- and zooplankton,and larvae across the shelf. It also facilitates primary production and influences food-web structure through its supply of silicate and micronutrients. Small-scale phenomena such as plume fronts and internal waves generated by the plume can greatly affect vertical mixing between the plume and ocean waters. Internal waves that are generated at the front of the river plume and propagate off shoreward [Nash and Moum 2005; Orton and Jay 2005] both cause mixing and transport plume water into the adjacent coastal ocean. We use Synthetic Aperture Radar (SAR) images and …
