Hydroacoustic Data to Support Embayment Monitoring in Long Island Sound, Southport and Saugatuck Embayments, Connecticut, 2022-2024

This data release includes hydroacoustic data for the 2022 to 2024 water years at four stations. These stations are part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Departments of Energy and Environmental Protection. The data were collected using acoustic Doppler current profilers (ADCPs) sampling 134 parameters every six minutes. Recorded values above the water surface or errant values due to environmental limitations were removed from files using an R script. The ADCPs were deployed at upstream and downstream locations in the Southport and Saugatuck embayments. For the Southport (Mill River) embayment, the upstream station is the Mill River at Pequot Yacht Club at Southport, CT USGS streamgage (410757073165601), and the downstream station is the Mill River at Southport Harbor near Southport, CT USGS streamgage (410729073171701). For the Saugatuck embayment, the upstream station is the Saugatuck River US Route 136, near Saugatuck, CT USGS streamgage (410724073221001), and the downstream station is the Saugatuck River Lower Embayment near Saugatuck, CT USGS streamgage (410613073215801). Data are provided for each station in a zip file and each zip file includes a description for the station’s ADCP setup.
