Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on May 24, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey, there were 0.02 inches of precipitation recorded at T.F. Green. Despite the lack of recent rainfall, all sites exhibited strong density stratification except for Point St Bridge, which exhibited moderate density stratification.
Dissolved oxygen (DO) conditions remained above the hypoxia threshold (2.9 mg/L) at all sites this week; the lowest DO observed was approximately 4.56 mg/L in the bottom waters of Phillipsdale landing. Fluorescence was low to moderately elevated this week, with the highest value (25.3 mg/m3) observed at Pomham Rocks.
