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

AI Summary

Scientists at Los Alamos National Laboratory have created one of the first long-term acoustic baselines for the Arctic underwater soundscape to enhance monitoring amid retreating sea ice and increasing geopolitical competition. This research aids in detecting natural and human-made underwater events relevant to national security.

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.
