USV Successfully Identifies Hypoxic Zones in Gulf of Mexico

SeaTrac deployed its SP-48 uncrewed surface vehicle (USV) to identify potential hypoxic zones in the Gulf of Mexico, collaborating with the University of Southern Mississippi (USM) and NOAA’s OMAO. The 14-day project aimed to validate the USV’s ability to collect real-time data while minimizing manpower and resource expenditures typically associated with crewed vessels.

Equipped with a deep keel and robust satellite communications, the SP-48 was outfitted with an AML-3 Sonde and various sensors for measuring environmental conditions. Despite challenging operational conditions, including high winds and rough seas during December 2023, the USV effectively managed its power budget and performed continuous sampling at depths up to 222 feet. Adjustments were made to enhance system tuning, ensuring reliable data collection.

Throughout the mission, the SP-48 demonstrated its operational autonomy, conducting three separate 24-hour station-keeping periods without manual intervention. This level of operational reliability allowed real-time data to be transmitted to USM while maintaining consistent communication links. According to USM officials, the successful deployment of the SP-48 showcased its effectiveness in collecting quality data, significantly reducing on-site personnel needs while proving suitable even in adverse sea states.
