Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on May 31, 2023 using a Seabird Electronics profiler. There was no precipitation recorded at T.F. Green in the three days leading up to the survey. All sites exhibited strong density stratification except for Pomham Rocks, which was 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 3.01 mg/L in the bottom waters of Edgewood Shoal. Fluorescence was fairly low this week, ranging from 1.80 to 11.9 mg/m3.
