Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on June 21, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey, there was no precipitation recorded at T.F. Green. Density stratification was moderate to strong at the sites surveyed.
Dissolved oxygen (DO) conditions remained above the hypoxia threshold (2.9 mg/L) at most sites this week; the lowest DO observed was approximately 3.76 mg/L near the surface of Phillipsdale Landing. Fluorescence was low to moderately elevated this week, with the highest value (21.44 mg/m3) observed at Pawtuxet Cove.
