Briefings

Los Alamos National Laboratory established the first long-term acoustic baseline for the Arctic's underwater soundscape to monitor seismic events, ship traffic, and resource development as sea ice retreats. This initiative aims to improve global security monitoring of the region's dynamic environment.

Key points

• Los Alamos National Laboratory established the first long-term acoustic baseline for the Arctic's underwater soundscape to monitor seismic events, ship traffic, and resource development.
• The project strengthens detection and interpretation of earthquakes, underwater and nearshore detonations, and other national security events in the region.

Context and limitations

Data collection covers only the Arctic region; specific dates for baseline establishment are not provided, and long-term trends remain unmeasured.
