Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on September 6, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, no precipitation was recorded at T.F. Green. Most sites were moderately to weakly stratified this week.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at the Pomham Rocks, India Point Park, and Phillipsdale Landing sites. The highest fluorescence readings for the week were measured around 1.5 meters below the surface at Edgewood Yacht Club.
