Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on June 14, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey, there were 0.21 inches of precipitation recorded at T.F. Green. India Point Park exhibited strong density stratification and all other sites were moderately stratified.
Dissolved oxygen (DO) conditions remained above the hypoxia threshold (2.9 mg/L) at all sites this week; the lowest DO observed was approximately 4.05 mg/L in the middle waters of Phillipsdale Landing. Fluorescence was fairly low this week, ranging from 1.28 to 13.38 mg/m3.
