Pacific Ocean Shelf Tracking

Project Description
The Pacific Ocean Shelf Tracking (POST, project aims
to build an acoustic tracking array along the west coast of North America. The
early applications focused on tracking the migration, life span, movement and
behaviour of Pacific salmon. The project is expanding to encompass other
species such as rockfish, sturgeon and small pelagics.

The test array in the Salish Sea region, deployed in 2004-2005, demonstrates
that a large-scale monitoring system could be established to answer long-asked
questions about the lives of marine species.

The Pacific Ocean Shelf Tracking Project plans to complete the permanent
full-scale marine telemetry array along the North American Pacific coast, from
Baja to the Bering Sea, by 2010. The array will have 2000 receivers and 30
listening lines, each up to 50 km long. Capable of listening to over 250,000
animals at once, it will permit a near-complete census of the movements and
marine survival of animals ranging from small salmon smolts to large marine

Funding was made possible by the Alfred P. Sloan Foundation and the Census of
Marine Life (click here for funding proposal), as well as the Gordon and Betty
Moore Foundation.
