Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on November 15, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.01 inches of precipitation were recorded at T.F. Green. Stratification ranged from well-mixed at sites like Bullock Reach Buoy to moderately stratified at sites including Phillipsdale Landing and Pomham Rocks.
Dissolved oxygen (DO) conditions were not observed to be below the hypoxia threshold (2.9 mg/L) at any site profiled this week. The highest fluorescence readings for the week were measured around 3 meters below the surface at Edgewood Shoal.
