Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on July 12, 2023 using a Seabird Electronics profiler. In the three days leading up to the survey, there were 1.91 inches of precipitation recorded at T.F. Green. Strong density stratification was observed at all sites surveyed this week.
Dissolved oxygen (DO) conditions were above the hypoxia threshold (2.9 mg/L) at Conimicut Point West; all other sites surveyed had hypoxic conditions in the middle and/or lower half of the water column. Fluorescence was moderately elevated at the surface of Conimicut Point West this week and relatively low at all other sites.
