Autonomous Underwater Vehicles (AUV) for Farm Monitoring

Autonomous underwater vehicles navigate a pre-programmed survey path through or around a cage, pond, or farm site without real-time human piloting, collecting video, sonar, or water quality sensor data along the route, a distinct operating mode from remotely operated vehicles, which require continuous human control via a tethered or wireless link, meaning AUVs can cover larger survey areas or longer missions without requiring an operator's continuous attention but offer less flexibility to react and adjust to something unexpected observed mid-mission compared to a human-piloted ROV. Farm applications include routine net integrity inspection, benthic condition surveying beneath and around cages, and water quality profiling across a site's full water column on a repeatable, consistent survey path that produces directly comparable data from one survey to the next, a consistency advantage over manual diver inspection, which can vary in coverage and thoroughness depending on which specific areas a given diver happened to focus on during any particular dive. Battery endurance and data transmission remain practical operating constraints, since most AUVs must surface or be retrieved to offload collected data and recharge rather than streaming large volumes of video or sonar data in real time over long-range underwater wireless links, meaning AUV survey results are typically reviewed after mission completion rather than monitored live during the survey itself. Integration with a farm's broader benthic and water-quality monitoring program, feeding AUV-collected data into the same data historian and reporting systems used for other farm sensor data, is increasingly standard practice specifically so AUV survey results contribute to the same trend analysis and compliance reporting as other monitoring data sources rather than existing as an isolated, separately managed dataset.
