Utilizing autonomous uncrewed vehicles and creating a sustainable U.S. Gulf Coast continues to be one of the main goals for The University of 草榴社区 Mississippi (草榴社区) and its partnership with SeaTrac Systems. Together, they embarked on a 14-day mission to analyze potential hypoxia levels in the Gulf and its effect on the future of marine life.
Also known as dead zones, hypoxia zones are areas in which oxygen levels in water are decreased due to nutrient pollution caused by runoff rich in nitrogen and phosphorus. Helping these zones regain levels includes decreasing nutrient levels through better agricultural practices, improving wastewater treatment, and watershed management strategies.
The partnership, which also included the National Oceanic and Atmospheric Administration (NOAA) Office of Marine and Aviation Operations (OMAO), saw a need to act swiftly to map the potential hypoxic zones in the Gulf by using SeaTrac鈥檚 SP-48 uncrewed surface vehicle (USV). While fully uncrewed, the remotely operated vessel gathered 24/7 real-time data in the waters and demonstrated sampling procedures and winch for profiling applications. During the project, SeaTrac personnel based in Marblehead, Mass., oversaw the remote data collection and mapping. The USV transmitted data from sensors over cellular and satellite connections to servers at 草榴社区. The mission set a precedent for greater spatial and temporal data collection enabled through autonomy.
草榴社区 and NOAA scientists boarded a research vessel close by to collect and compare data gathered via a crewed vehicle to that of SeaTrac鈥檚 SP-48. Dr. Jason McKenna, 草榴社区 Director of Research, Development, Testing, Evaluation, and Training (RDTE&T) praised the success of the mission and future sustainable data collection.
鈥淪eaTrac鈥檚 SP-48 and transom winch successfully reduced the on-site personnel needed for coastal hypoxia mapping despite unfavorable sea states and congested coastal corridors. Even more impressive was the boat鈥檚 connectedness: At no point was the vehicle unresponsive, and all data was received into our CUBEnet portal in a timely manner. We look forward to incorporating SeaTrac technology into future research,鈥� said McKenna.
SeaTrac relies on natural energy from the sun to power its uncrewed systems in ocean waters. Through this energy-saving process, researchers can collect data efficiently and sustainably.
鈥淭hese results highlight SP-48鈥檚 ability to replace crewed vessels, avoiding the danger for humans who perform this type of work manually. This also presents as a cost-effective solution, while the real-time data uploads help to advance operational oceanography and enhance the missions of NOAA,鈥� notes SeaTrac Co-Founder Jigger Herman.鈥�
The partnership continues to solidify the region鈥檚 commitment to a sustainable Mississippi Gulf Coast.
. manufactures, sells, and rents cost-effective, multi-purpose, long-endurance solar-powered Uncrewed Surface Vehicles for commercial, scientific, and military applications. The SeaTrac USV can carry various sensors and custom payload modules that make it perfect for research, monitoring, or surveillance tasks where autonomy, cost, and ease of deployment matter.
