Passive Acoustic Deployments

NOAA NEFSC and its partners have been deploying bottom-mounted Marine Autonomous Recording Units (MARUs) since 2006 to record sound in the northwest Atlantic. The MARUs collect and store acoustic data for several weeks or months until retrieval. Data collected from the buoys are being used to characterize ocean noise, study the acoustic behavior of marine mammals and fish, and to gain a better understanding of the abundance and distribution of species in these waters.

To view different acoustic deployments, drag the bars on the bottom left through the timeline. You can also click through deployments in order of events by the arrows on either side of the deployment details. Information on the bouys can also be viewed as a spreadsheet.
