This nearshore sensor (NS15) operated between July 7, 2012 and November 5, 2018. It was located in Pago Bay near the mouth of the Pago River on the eastern shore of Guam. The sensor package was mounted to the sea floor at approximately 1.5 meters depth. Data were transmitted every 4 minutes. PacIOOS nearshore sensors monitor coastal water conditions to help provide early indications of potentially polluted run-off from storm drainage, sewage spills, and soil erosion from land-based waterways such as streams and other outflows that lead directly into the ocean. Owned and maintained by PacIOOS under the supervision of Dr. Margaret McManus and lab. The University of Guam is a key partner.

This mooring’s follow-on mission, nearshore sensor NS17, is located 77 feet (23 meters) south of NS15 in order to minimize burial of the sensor by silt. Click here for more recent data at the NS17 site, which begin March 2019.
