Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on October 25, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, trace amounts of precipitation were recorded at T.F. Green. Stratification varied between the profiled sites this week, from weak stratification at Pomham Rocks and Point Street Bridge, to strong stratification at India Point Park, Phillipsdale Landing, and Pawtuxet Cove.
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 1.5 meters below the surface at Pawtuxet Cove.
