Hourly maps of surface currents were made using SeaSonde HF systems deployed in northern Oregon and southern Washington on the Columbia River from June 2004 to December 2006. The instruments were operated near 5 MHz, which allowed long-range measurements of radial currents from each station. Where data from different stations overlapped, two-dimensional currents were produced by mapping to a fixed grid. Data quality measures including GDOP (geometric dilution of precision), are also included.
