Nutrient samples were collected from thirteen river stations and nine bay stations on May 29th. In the five days prior to sampling, there were 0.37 inches of precipitation recorded at T.F. Green.
Among the river stations sampled, the highest total nitrogen (TN), total dissolved nitrogen (TDN), and dissolved inorganic nitrogen (DIN) concentrations were observed at Ten Mile River @ Central Ave. (TN = 1,380 ppb, TDN = 1,340 ppb, DIN = 948 ppb). The lowest TN and TDN were observed at Moshassuck River @ Higginson Ave. (TN = 658 ppb, TDN = 590 ppb), while the lowest DIN was at Coles River @ Milford Rd. (DIN = 188.6 ppb, average of duplicates).
Among the bay stations sampled, the highest surface TN, TDN and DIN were observed at Phillipsdale Landing (TN = 1,070 ppb, TDN = 931 ppb, DIN = 648 ppb). The lowest surface TN were observed at Bullock Reach Buoy (TN = 698 ppb), while the lowest surface TDN and DIN were observed at Conimicut Point (TDN = 333 ppb, DIN = 165 ppb). Chlorophyll a concentrations at the surface bay stations averaged 1.67 μg/L overall with a maximum of 4.05 μg/L at the Edgewood Shoal.
The next scheduled sampling date is June 12, 2024.
