Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on December 13, 2023 using a Seabird Electronics profiler. In the five days leading up to the survey, 2.29 inches of precipitation were recorded at T.F. Green. Most sites were strongly stratified this week, with the exception of Pawtuxet Cove, which was dominated by freshwater, showing the impact of the major rain storm this week.
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 3 meters below the surface at Phillipsdale Landing.
