Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on July 8, 2025 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.55 inches of precipitation were recorded at T.F. Green. Water column stratification varied between the sites this week from well-mixed at Pawtuxet Cove to moderately stratified at Pomham Rocks, India Point Park and Phillipsdale Landing.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at India Point Park, Pomham Rocks, Bullock Reach Buoy, Edgewood Yacht Club, and Edgewood Shoal, and in the middle and lower portion of the water column at Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at Phillipsdale Landing.
