Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on August 14, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 1.32 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from weakly stratified at Point Street Bridge, India Point Park, Pomham Rocks and Edgewood Yacht Club, to strongly stratified at Phillipsdale Landing.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Pomham Rocks, in the middle and lower portions of the water column at Edgewood Yacht Club, and in all portions of the water column (upper, middle and lower) at Point Street Bridge, India Point Park and Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at Phillipsdale Landing.
