Ocean State Sensing is a blue technology and engineering company based in Newport, Rhode Island, focused on advancing our understanding of the ocean through high-resolution sensing and data. Specializing in underwater thermal mapping, OSS develops and deploys innovative fiber optic Distributed Temperature Sensing (DTS) systems that provide continuous, real-time measurements throughout the water column, even while underway.

Through its ThermoTrawl suite of products, Ocean State Sensing delivers precise, actionable environmental data to a wide range of maritime users, including commercial fisheries, oceanographic researchers, and defense organizations. By capturing fine-scale temperature structure in active ocean environments, the company helps improve operational efficiency, support scientific discovery, and enable more informed decision-making at sea. ThermoTrawl’s wide range of applications include: reducing bycatch in fisheries, climatological baselining, and understanding ecological shifts for dynamic fisheries management.

Driven by a mission to enhance stewardship of the marine environment, Ocean State Sensing combines deep ocean engineering expertise with practical, at-sea experience. Its integrated approach, spanning instrumentation, data collection, and system deployment, supports efforts to better understand changing ocean conditions and sustainably manage marine resources.
