This regional mission established a high-frequency glider time series (Figure 2) in Puget Sound with seasonal (spring/fall) deployments. Led by student pilots, these missions navigate complex coastal environments—ferry routes, shipping lanes—and observe tidal exchange, oxygen variability, and temperature-salinity structure. The time series aims to detect seasonal and interannual climate-driven changes in local water properties.
Gliders SG175 and SG194 (Figure 3) completed the first two-week deployment in May 2024. Undergraduate researchers are now analyzing the data for tidal dynamics, model validation, and oxygen calibration. With future funding, the time series will be integrated into the NANOOS observing system and expanded to support passive acoustic monitoring of marine mammals, including Southern Resident killer whales and humpback whales.
