POST background
POST began with a simple question: What happens to salmon when they leave the rivers and enter the ocean? Before 2000, scientists knew little about salmon migration at sea. But acoustic telemetry was being developed rapidly and the Atlantic Salmon Federation recognized its potential as a tool to address this lack of knowledge.
In 2001 and 2002, the Census of Marine Life funded a small pilot project, originally named the Pacific Ocean Salmon Tracking Project, to demonstrate the feasibility of a permanent, continental-scale telemetry system on the west coast of North America. This allowed researchers to examine marine movements and early ocean survival of both hatchery-raised and wild salmon.
Preparations were made to scale up the demonstration in 2003. In 2004-2005, CoML and the Gordon and Betty Moore Foundation funded a large-scale study in the Salish Sea region, the large, dilute, estuarial inland sea that includes what is now called Puget Sound, the Strait of Georgia, and other water, including the Strait of Juan de Fuca, which connects the Georgia-Puget Basin to the Pacific.
The project was renamed the Pacific Ocean Shelf Tracking Project to acknowledge the technology's ability to track many marine species.
POST's results have begun answering questions about salmon migration. More importantly, the large-scale demonstration justified installing permanent POST listening lines in 2006, originally spanning more than 1,500km of the Pacific Coast from Southeast Alaska to Northern Oregon.
In 2007, POST maintained the permanent array and download data from all receivers, providing researchers with valuable data on movement and survival.
This year and going forward POST is maintaining and expanding its permanent system, with new lines that will fulfill the vision of an array from the Baja Peninsula to the Bering Sea, providing unprecedented opportunity to discover more about
