Recent advances in distributed acoustic sensing (DAS) offer the potential to conduct wide-area surveys of bioacoustic activity that would be logistically infeasible with traditional hydrophone measurements. Here, a 2.2\u2009km DAS cable deployed in Narragansett Bay, RI, was used to map the spatial distribution of oyster toadfish chorusing over a 24-h period during their spawning season in June 2025. A localization technique was developed where nearfield beamforming was performed along a rolling subaperture across the entire array, in order to account for the lack of coherence across widely spaced channels. This method allowed for the localization of biological hotspots, which were concentrated along a breakwater at the east side of Narragansett Bay. Long-term, single-hydrophone recordings also reveal seasonal and diel patterns for the same toadfish chorus, demonstrating how temporal data from traditional acoustic sensors can complement spatial DAS measurements.<\/jats:p>","DOI":"10.1121\/10.0044594","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T11:49:36Z","timestamp":1787140176000},"page":"1625-1631","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Mapping the spatial distribution of chorusing oyster toadfish (\n                    <i>Opsanus tau<\/i>\n                    ) with distributed acoustic sensing"],"prefix":"10.1121","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1949-1981","authenticated-orcid":false,"given":"Daniel","family":"Duane","sequence":"first","affiliation":[{"name":"Naval Undersea Warfare Center , Newport, Rhode Island 02841,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Walsh","sequence":"additional","affiliation":[{"name":"Naval Undersea Warfare Center , Newport, Rhode Island 02841,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darren","family":"Flynn","sequence":"additional","affiliation":[{"name":"Naval Undersea Warfare Center , Newport, Rhode Island 02841,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren A.","family":"Freeman","sequence":"additional","affiliation":[{"name":"Naval Undersea Warfare Center , Newport, Rhode Island 02841,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"key":"2026081907493129800_c1","doi-asserted-by":"publisher","first-page":"847","DOI":"10.1007\/s11160-025-09936-9","article-title":"Passive acoustic monitoring of fish choruses: A review to inform the development of a monitoring and management tool","volume":"35","year":"2025","journal-title":"Rev.
