Water column profiles were conducted at five locations in the Providence and Seekonk River estuaries on August 16, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.59 inches of precipitation were recorded at T.F. Green. Most sites were moderately to strongly stratified this week.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) throughout the water column (upper, middle and lower portions) at the Point Street Bridge, India Point Park, and Phillipsdale Landing sites, but only in the middle and lower portions of the water column at Bullock Reach Buoy and Conimicut Point. The highest fluorescence readings for the week were measured around 1.5 meters below the surface at Conimicut Point.
