ThermoTrawl systems use Distributed Temperature Sensing (DTS) fiber optic cable to measure temperature throughout the entire water column in real time.  ThermoTrawl’s towed or moored systems use a compact and convenient interface that allows users to track fine-scale dynamic changes in any body of water, making it the new standard in oceanographic temperature profiling.

​

​Unlike existing tools, such as satellite surface data, single-point sensors, or manually deployed profilers, OSS ThermoTrawl system continuously measures temperature at 25 cm intervals over 800+ meters, providing instantaneous, actionable thermal insights to fishers, researchers, and maritime stakeholders.

 

ThermoTrawl’s proven DTS technology has been used by the oil and gas industry for decades, but has remained prohibitively expensive and cumbersome to be widely used for smaller-scale applications; until now. 

 

OSS’s ThermoTrawl family of products (ThermoTrawl/MICRO/CUSTOM) can be scaled for affordability and use on any sized vessel or mooring for: 

​

• Fisheries: Accurately target temperature dependent species depths underway, saving fuel, and reducing bycatch by 10% or more.
   

• Defense Sector: Support real-time environmental awareness and optimum sensor placement to maximize both passive and active acoustic performance. 
   

• Climate Research: ThermoTrawl's fine resolution data can be used for nuanced climatological baselining, profiling current meandering, meltwater mixing, current strength and position, internal waves, and real-time trend observations.
   

• Ecology: Marine researchers and policy managers can use ThermoTrawl data to calibrate models, monitor ecosystem shifts, and manage fisheries more dynamically. Moored ThermoTrawl systems can be used in aquaculture to determine infrastructure placement for maximum growth potential and monitoring.
