Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on July 2, 2025 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.02 inches of precipitation were recorded at T.F. Green. Water column stratification varied between the sites this week from well-mixed at Point Street Bridge and Pawtuxet Cove to moderately stratified at India Point Park and Phillipsdale Landing.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the middle and lower portion of the water column at Edgewood Yacht Club and India Point Park, and in all portions (upper, middle, and lower) of the water column at Point Street Bridge and Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at Pawtuxet Cove.
