Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on October 11, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.36 inches of precipitation were recorded at T.F. Green. All sites were strongly 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 Edgewood Yacht Club site. The highest fluorescence readings for the week were measured around 2 meters below the surface at Conimicut Point.
