Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on July 24, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.06 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from well-mixed at Pawtuxet Cove and Phillipsdale Landing, to moderately stratified at sites such as Bullock Reach Buoy 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 the Bullock Reach Buoy, and in the lower and middle portions of the water column at the Pomham Rocks, India Point Park, Edgewood Yacht Club, and Edgewood Shoals sites. The highest fluorescence readings for the week were measured around 1.5 meters below the surface at Pawtuxet Cove.
