Alternate Leg ID: IB E-30-00-WA

Area of Operations: John Day Reservoir, Columbia River, Washington, Oregon, United States, North America

Dates: September 13, 2000 to September 28, 2000

Objectives: High-resolution seismic reflection, sidescan mapping, and sediment sampling of reservoir floor to determine the amount, distribution and types of sediment being trapped. These data are important to understanding changes in salmon spawning grounds and to quantifying changes in sediment supply to the coast.
