Sequim Bay Underwater UXO Prototype Demonstration Site: Field Operations Summary, 2020
Abstract
(MR-2735) in 2020. Testbed development and field operations were conducted by PNNLs Coastal and Marine Research Laboratory in support of the SERDP/ESTCP underwater MR program. A series of standardized UXO demonstration sites (testbeds) are being developed by SERDP/ESTCP to test, evaluate, and demonstrate technologies that can detect, geolocate, and classify proud and buried munitions in 035 m water depths. As a prototype demonstration site, Sequim Bay is a semi-enclosed marine waterbody containing sand and mud sediments with minimal clutter in 530 m water depths. MCRL is located at the entrance to Sequim Bay, where it provides operational, logistical, andfacilities support for testbed activities. The primary objectives of Phase II were to (1) establish a calibration and blind site grid at the Sequim Bay testbed, including placement and retrieval of 30 targets in 2530 m water depths in sand/mud sediments; (2) provide operational support to the Applied Physics Laboratory University of Washington (APL-UW) for an engineering field test of their acoustic sensor platform; (3) evaluate target geolocation systems to support accurate placement of targets; and (4) support collection of targetground truth information for scoring protocol development by the MR program. Phase II was accomplished by building on lessons learned from Phase I in 2019, and focused on developing cost-effective, safe, and technically sound approaches that can inform future operations of the Sequim Bay testbed and other underwater demonstration sites.
