SWAG视频 School of Ocean Science and Engineering Sets New SWAG视频 Record for Glider Mission

Kevin Martin, Affiliate Senior Instrumentation Specialist and Ocean Observing Manager of the SOSE, has been conducting glider missions with SWAG视频 since 2012 and is ecstatic about the new record for SWAG视频鈥檚 glider fleet.
鈥淲e try to operate during hurricane season,鈥� Martin said. 鈥淲e usually don鈥檛 get them out [in the water] until about August. The longest mission I had before this was 120 days.鈥�
The glider started its mission in May 2023 with a goal to last a majority of hurricane season out in the open ocean. For 165 days, the glider recorded and sent data back to Martin and the Global Telecommunication System (GTS) for use in the ocean models that are used in the process of producing hurricane forecasts by the National Hurricane Center of the National Oceanic and Atmospheric Administration (NOAA).
The glider uses buoyancy to navigate through the water, and Martin programs command data to tell the glider where to go and what to do, then commanding the glider to dive underwater to collect more data used for research. Once it reaches the surface, the data is sent to Martin, and then SWAG视频 students analyze the findings; Martin can even control the glider from his cell phone thanks to new technologies.
Ocean currents play a major role in the glider鈥檚 mission. Because gliders are slow-moving vehicles, currents affect its movement, and depending on the currents鈥� impacts and location, Martin can command where to move the glider for optimal data collection.
鈥淵ou learn the currents,鈥� said Martin. 鈥淭he glider will call in about every six hours. At 1000-meter dive, it goes down, then comes back up to the surface. I鈥檒l look at where it was before and where it鈥檚 going, and potentially what it could do next.鈥�
SWAG视频 has been involved in glider research and missions since 2012, initially with government and industry partners. The project is part of Dr. Stephan Howden鈥檚 Ocean Observing Lab at SWAG视频. The National Oceanic and Atmospheric Administration (NOAA) helped start a larger glider initiative that includes missions in the Gulf of Mexico, the Caribbean Sea, the South-Atlantic Bight and Mid-Atlantic Bight in 2018. The focus was to observe hurricane-prone areas, water temperatures, for storm intensity forecasting.
Glider operators use the uncrewed systems to analyze ocean health content to better observe ocean data for hurricane intensification models. With time, parts to assemble gliders have become expensive, but Martin鈥檚 goal is to analyze data year-round and observe on winter storms in addition to hurricanes.
鈥淭he goal would be year-round operations with our glider fleet expanding,鈥� said Martin.
