Water Column Profiles
Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on August 28, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 1.38 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from well-mixed at Point Street Bridge, to moderately stratified at Phillipsdale Landing, Pomham Rocks, and India Point Park
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Pomham Rocks and India Point Park, and in all portions of the water column (upper, middle and lower) at Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at India Point Park.

Water Column Profiles
Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on August 21, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.48 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from weakly stratified at seven of eight sites, to moderately stratified at Phillipsdale Landing.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Edgewood Yacht Club, in the middle and lower portions of the water column at Edgewood Shoals, and in all portions of the water column (upper, middle and lower) at India Point Park. Conditions at Phillipsdale Landing did not dip below the hypoxia threshold but did approach it in the lower portion of the water column. The highest fluorescence readings for the week were measured around 1.5 meters below the surface at Bullock Reach Buoy.

Water Column Profiles
Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on August 14, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 1.32 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from weakly stratified at Point Street Bridge, India Point Park, Pomham Rocks and Edgewood Yacht Club, to strongly stratified at Phillipsdale Landing.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Pomham Rocks, in the middle and lower portions of the water column at Edgewood Yacht Club, and in all portions of the water column (upper, middle and lower) at Point Street Bridge, India Point Park and Phillipsdale Landing. The highest fluorescence readings for the week were measured around 1 meter below the surface at Phillipsdale Landing.

Water Column Profiles
Water column profiles were conducted at seven locations in the Providence and Seekonk River estuaries on August 7, 2024 using a Seabird Electronics profiler. In the five days leading up to the survey, 0.95 inches of precipitation were recorded at T.F. Green. Water column stratification at the sites varied from weakly stratified at Pawtuxet Cove and Edgewood Yacht Club, to strongly stratified at Conimicut Point.
Dissolved oxygen (DO) conditions were below the hypoxia threshold (2.9 mg/L) in the lower portion of the water column at Edgewood Yacht Club, in the middle and lower portions of the water column at Pomham Rocks, and in all portions of the water column (upper, middle and lower) at India Point Park and Phillipsdale Landing. The highest fluorescence readings for the week were measured around 2 meters below the surface at Edgewood Yacht Club.
