Water column profiles were conducted at six locations in the Providence and Seekonk River estuaries on September 27, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 2.77 inches of precipitation were recorded at T.F. Green. All sites were strongly or moderately 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 India Point Park site, and in the lower and middle portions of the water column at Point Street Bridge. The highest fluorescence readings for the week were measured around 3 meters below the surface at the Bullock Reach Buoy.
