UGOS (GODEEP/LC-Floats): Near Real-time Hydrography and Deep Velocity in the Loop Current System using Autonomous Profilers
Amy Bower (WHOI), Steve Jayne (WHOI), Heather Furey (WHOI). Collaborator: Paula Perez-Brunius (CICESE)
A fleet of 20-25 autonomous profilers deployed in the Loop Current System (LCS) active area in the eastern Gulf of Mexico are part of the NAS Understanding Gulf Ocean Systems campaign, and provide publicly-available near-real-time data to weather forecast models to aid in hurricane prediction. These data are also being used in conjunction with c-PIES data to explore the physical mechanism of Loop Current expansion into the Gulf and subsequent Loop Current Ring formation. Read More

Figures
Time series of number of profiles collected by UGOS-funded Argo floats in the Gulf of Mexico from July 2019-August 2024. The red dots represent total profiles collected throughout the Gulf, the green dots represent number of profiles collected within the eastern Gulf only (between 90W and 81W), and the blue dots represent number of profiles collected within the eastern Gulf in water deeper than 2000 m.
