The Columbia River Plume is a highly dynamic water mass that supplies silicate and trace metals, fresh water, and dissolved and particulate organic matter to the Oregon/Washington shelf. The optical and physical properties of the river plume evolve as it travels away from the river mouth and undergoes both aging and dilution by surrounding waters. The objectives of this study were to (1) identify initial optical properties of fresh plume waters at the river mouth, (2) track changes in the optical signature of the water mass as it advects seaward from the mouth, and (3) predict residence time of the water mass on the shelf from changes in the optical signature, using remote sensing data. These results are compared to central California, where river plumes are much more episodic and spatially smaller, to determine the limits of detection using standard (1 km) and high-resolution (250 m) data from the MODIS platform.
