Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on June 28, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey and the morning of, there were 0.92 inches of precipitation recorded at T.F. Green. Strong density stratification was observed at most sites surveyed this week, with Bullock Reach Buoy and Conimicut Point West exhibiting moderate density stratification.
Dissolved oxygen (DO) conditions remained above the hypoxia threshold (2.9 mg/L) at most sites this week but were below the hypoxia threshold in the bottom waters of Phillipsdale Landing (1.01 mg/L) and Edgewood Shoal (0.57 mg/L). Fluorescence was low to moderately elevated this week, with the highest value (32.52 mg/m3) observed at the surface of Phillipsdale Landing.
