The pair of sites in Prince William Sound are located in Knowles Bay, north of Orca Bay and also just north of Shelter Bay on Hinchinbrook Island. These two sites have a clear view of central Prince William Sound. This HF Radar system has already provided new insight on the circulation of Prince William Sound, as well as information on the tidal currents in the region. These systems will be operational for the summer of 2008 but are currently decommissioned. Funding for these systems is being provided by grants awarded by the National Aeronautical and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), the Prince William Sound Regional Citizens Advisory Corporation (PWSRCAC), and the Alaska Ocean Observing System (AOOS).
During the summer of 2005, the Salmon Project temporarily operated two additional sites in the Northern Gulf of Alaska: one at Rugged Island on the southern end of Resurrection Bay and the other on the western end of Middleton Island. The goal of this HF Radar system was to address the effects of the Alaskan Coastal Current and the Alaskan Stream on the circulation of the shelf of the Gulf of Alaska.
