About the Project

The Hudson River Estuary supports a wide range of fish, including a number of migratory and endangered species. Advances in ecosystem monitoring technologies, including passive acoustic monitoring, have enabled the Hudson River NERR to address critical management challenges including understanding how fish species use the estuary, monitoring species population dynamics of protected and endangered animals, and creating engaging communication tools that inspire public stewardship of key fish species. In close collaboration with HRNERR, NYSDEC, and Cornell University, this project team implemented passive acoustic monitoring techniques. With the resulting monitoring data, the team characterized a diverse range of soundscapes across latitudinal and salinity gradients along the Hudson River, and compared sounds from tributary and wetland habitats to those of the main channel of the river.

About this Resource

The project inspired the Hudson Ecological Listening Laboratory and Observatory (HELLO), a public listening exhibit hosted at Hudson River NERR’s Norrie Point Environmental Center. Visitors can use this interactive acoustic exhibit to listen to curated sound clips from this from the Hudson River and beyond.
