Passive Acoustic Deployments

NOAA NEFSC and its partners have been deploying bottom-mounted recorders since 2004 to record sound in the northwest Atlantic. The recorders collect and store acoustic data for several weeks or months (up to two years) 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, visit our deployment map application (CLICK ON THE MAP) below. Click on the timer button in the bottom center to begin an automatic slide show through time of recorders deployed. Hover over the dates at the bottom to bring up a menu to pause/play the slideshow, or adjust the time range shown by expanding the blue endpoints when the slideshow is paused. Click on any recorder on the map to get specific information of that recorder. A list of each recorder and corresponding information can be viewed and filtered using the table icon on the bottom right. Information can also be viewed as a Google Doc spreadsheet.
