During these periods, high-frequency measurements were taken every 15 minutes using an autonomous logger (HOBO®) attached to a mooring to record pH, practical salinity, light, temperature, and water level. Note that in 2024, data are missing from May 15 to 21 due to partial burial caused by a significant episode of sediment resuspension.
