PacWave continues to maintain a network of site monitoring equipment, seafloor instrumentation, and subsea cable infrastructure throughout the PacWave South wave energy test site, approximately 7 nautical miles WSW of the Yaquina Bay Entrance. Some of the monitoring buoys are low profile and may be difficult to see in elevated sea states. All buoys have a yellow hull, are lighted with a flashing amber light, and are deployed as single-point moorings. PacWave has also installed four long-term surface marker buoys that visually delineate the corners of the test site: NW (44°34.9988'N, 124°14.4998'W), NE (44°35.0465'N, 124°13.1008'W), SE (44°33.0437'N, 124°12.9700'W), and SW (44°33.0000'N, 124°14.3730'W). These corner markers are approximately 9 feet tall, have a yellow / red hull, a fixed yellow tower structure with integrated radar reflector, green grating on the lower half of the tower, reflective tape on the upper tower, and are lighted. These markers are also single-point moorings and will remain in place as part of PacWave’s maintained offshore infrastructure. Mariners should be aware that subsurface equipment and mooring components may also be present. Mariners are requested to avoid the test site if possible and to use caution when navigating in or near the area. For additional information, contact [email protected] or 541-737-9023. If there is an emergency or concerns regarding this equipment, please call our 24 / 7 Watch Desk at 541-819-4096.
