Scientists map the changing sounds of the Arctic to strengthen global monitoring

As Arctic sea ice retreats, new shipping routes, expanding resource development and growing geopolitical competition are transforming one of the world's least-monitored regions. Scientists at Los Alamos National Laboratory have established one of the first long-term acoustic baselines for the Arctic's underwater soundscape. This work strengthens the detection and interpretation of earthquakes, underwater and nearshore detonations, ship traffic and other events of national security interest.
