Using Data To Understand
POST maintains a broad-scale array of more than 400 acoustic receivers, or hydrophones, that "curtain off" segments of the coast in British Columbia, Alaska, Washington, Oregon and California. Over 3,000 km of the Pacific coast of North America is "wired up" with POST lines of acoustic receivers, giving us accomplishments and discoveries such as:
- For the first time, juvenile salmon were tracked from the Columbia River's headwaters to the seas off Southeast Alaska, a journey of about 2,500km taking over three months.
- Unknown before POST, threatened green sturgeon from the Sacramento River, California were discovered regularly migrating to central British Columbia and as far as Alaska.
