Water column profiles were conducted at six locations in the Providence and Seekonk River estuaries on June 7, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey, there were 0.12 inches of precipitation recorded at T.F. Green. Phillipsdale Landing exhibited moderate density stratification and all other sites were weakly 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 4.65 mg/L in the bottom waters of Phillipsdale Landing. Fluorescence was low this week, ranging from 1.06 to 4.64 mg/m3.
