Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on August 28, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 1.38 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from well-mixed at Point Street Bridge, to moderately stratified at Phillipsdale Landing, Pomham Rocks, and India Point Park
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Pomham Rocks and India Point Park, and in all portions of the water column (upper, middle and lower) at Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at India Point Park.
