Puget Sound’s Waters Come from Deep Canyon

April 15, 2014 7:00 am | by Univ. of Washington | News | Comments

The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.
