Acoustic and Environmental Observation Network in the Northwest Atlantic (AEON, 2021-2026)

browse graphicAEON project logo
These data represent the raw passive acoustic data collected from Acoustic and Environmental Observation Network (AEON) in the U.S. Northwest Atlantic, which was developed and deployed in February 2021. This network of five observation nodes complements existing oceanographic monitoring infrastructure in the Gulf of Maine. The network provides simultaneous, long-term monitoring of soundscapes and multiple acoustically-relevant parameters such as marine mammal behavior and prey concentration at key locations where changes in the Labrador and Gulf Stream currents are projected to affect the Gulf of Maine.
