Retired U.S. Navy Cmdr. John Joseph, a researcher in the NPS Department of Oceanography and principal investigator on the project, said the effort has been funded by the school\u2019s Consortium for Unmanned Systems Education and Research (CRUSER), which is sponsored by the Office of Naval Research.<\/p>\n<p>\u201cPSAP started as a CRUSER project a few years ago when Yi Chao, Seatrec CEO and a well-known oceanographer, gave a talk at NPS about their energy-harvesting system,\u201d said Joseph, who recognized an opportunity to combine the school\u2019s expertise in undersea acoustics and research instrumentation with Seatrec\u2019s innovative energy harvesting technology.<\/p>\n<p>NPS excels at conducting applied research in the operating environment. For the first time, PSAP offers an ability to collect and send oceanographic and passive acoustic monitoring data in near real-time for an unlimited period, thanks to the profiler\u2019s ability to harvest energy from the temperature differences in the ocean, enough to fully power the instrumentation indefinitely.<\/p>\n<p>\u201cTheoretically, PSAP can be deployed once, communicate its acoustic information to remote operators in near real time for limitless periods without requiring retrieval to offload data, refreshment &#8211; such as swapping batteries or data storage, or replacement,\u201d explained Joseph. \u201cThese characteristics greatly reduce lifecycle costs of a continuous acoustic monitoring effort.\u201d<\/p>\n<p>Empowering student research and discovery is central to the institution\u2019s efforts with industry partners, and the PSAP Voyager\u2019s ongoing operational test \u2013 which can be monitored via the Seatrec website \u2013 has provided a trove of data for potential research.<\/p>\n<p>\u201cNow that we have a sizable amount of oceanographic and acoustic data collected by PSAP, we plan to have students in the undersea warfare and meteorology and oceanography curricula to use these data for thesis research,\u201d said Joseph.<\/p>\n<p>The role of acoustic sensing in Naval operations is far-reaching and fundamental to U.S. Navy and Marine Corps operations at sea, including undersea sensing and detection.<\/p>\n<p>\u201cPassive acoustic listening has many operational and research applications in the Navy, and our students at NPS conduct applied research to meet naval-unique needs for at-sea operations that require measurements of ambient noise, understanding the composition of soundscapes and monitoring of marine mammals,\u201d said Joseph. The autonomy and endurance of the PSAP Voyager \u201cprovides an unprecedented opportunity to collect acoustic data in real-time for very long periods in remote areas without the expense and logistical tail of ship support.\u201d<\/p>\n<p>\u201cSound is used to \u2018see\u2019 underwater and is vital to understanding the ocean and monitoring the movement of natural and man-made objects,\u201d added Yi Chao, Ph.D., Seatrec\u2019s CEO and Founder in a recent news release. \u201cPreviously, hydrophones required power from expensive underwater cables from shore or ships but our PSAP Voyager untethers hydrophones and provides nearly unlimited persistent monitoring of the ocean in an extremely economical way.\u201d<\/p>\n<p>While the technology promises to be useful for improving maritime domain awareness, it will also enhance U.S. naval oceanographic models for operational planning used to improve own-force sonar system performance.<\/p>\n<p>(This news story does not constitute an endorsement of Seatrec or its products and services by the Naval Postgraduate School, the Department of the Navy, or the Department of Defense.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The team\u2019s successful development of an innovative, self-powered autonomous underwater drone, known as the Persistent Smart Acoustic Profiler (PSAP) Voyager, has already delivered large swaths of oceanographic and passive acoustic data primed for NPS student research since it was deployed for the first time off the coast of Kona, Hawaii, in early November of 2024 [&hellip;]<\/p>\n","protected":false},"author":5,"featured_media":367928,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-367926","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/posts\/367926","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=367926"}],"version-history":[{"count":2,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/posts\/367926\/revisions"}],"predecessor-version":[{"id":367929,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/posts\/367926\/revisions\/367929"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=\/wp\/v2\/media\/367928"}],"wp:attachment":[{"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=367926"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=367926"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/adn.monetizemail.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=367926"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
