Located along the Salish Sea in the northwest corner of Washington State, Sequim Bay offers a mixed-sediment testbed area of coastal ocean floor ranging from 5 to 30 meters underwater.
Sequim Bay is free of native unexploded ordnance (UXO), contains appropriate substrate type and minimal clutter, with nearby operational, logistical and facilities support provided by Pacific Northwest National Laboratory (PNNL). Compared to the warm, clear waters of some other test sites, Sequim Bay provides a unique environmental setting to test UXO detection technology in cold, turbid water with a variety of seabed substrates.
