Los Alamos scientists map Arctic underwater sounds to improve monitoring
Scientists at Los Alamos National Laboratory have created a long-term acoustic baseline for the Arctic using seven years of data from the Beaufort Sea.
New baseline established in Arctic waters
Researchers deployed a hydrophone 500 meters deep to record continuous underwater sounds. This dataset allows experts to understand how the soundscape changes throughout the year. The work helps distinguish normal activity from unusual events like earthquakes or detonations.
Data supports national security interests
The study analyzes recordings from one of 12 sensors in the Ocean Noise Reference Station Network. Scientists say reliable detection requires first understanding what sounds are typical for the region. Long-term records are extremely rare in this part of the world.
