Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on October 4, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 1.27 inches of precipitation were recorded at T.F. Green. All sites were strongly or moderately stratified this week, other than Pomham Rocks, which was weakly stratified.
Dissolved oxygen (DO) conditions were not observed to be below the hypoxia threshold (2.9 mg/L) at any site profiled this week. The highest fluorescence readings for the week were measured around 2 meters below the surface at the Bullock Reach Buoy.
