Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on August 23, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 2.16 inches of precipitation were recorded at T.F. Green. Most sites were moderately to strongly stratified this week, with the exception of Edgewood Shoals, which was weakly stratified
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) throughout the water column (upper, middle and lower portions) at the Edgewood Shoals, India Point Park, and Phillipsdale Landing sites, but only in the middle and lower portions of the water column at Edgewood Yacht Club and Pomham Rocks. No hypoxic conditions were observed at Conimicut Point, Pawtuxet Cove or Bullock Reach Buoy. The highest fluorescence readings for the week were measured around 1 meter below the surface at Pawtuxet Cove.
