Video: Identifying sources of pollution in the Skagit Valley

A video produced by the University of Washington Center for Urban Waters shows how chemical tracers can identify sources of pollution affecting shellfish growers in Puget Sound’s Skagit Valley. Fecal coliform pollution is a widespread problem in Puget Sound, resulting in costly beach and shellfish bed closures whenever it is detected. Analytical techniques can now […]

Test your herring knowledge

By Jeff Rice One of the first steps in protecting any species is understanding as much as you can about it. When it comes to Pacific herring in the Salish Sea, much is known but until recently many of the key scientific findings about the species had not been gathered together in a single place. […]

Chemicals from automobile tires suspected in coho deaths

Findings authored this month by University of Washington scientists at the Center for Urban Waters and their collaborators provide new insight into “urban runoff mortality syndrome” affecting Puget Sound coho.   By Jeff Rice Chemicals linked to automobile tires have been found in stormwater associated with the widespread deaths of coho salmon in Puget Sound. The […]

Dispatches: Ancient DNA reveals ecological history

Occasionally, this space includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Social scientist Whitney Fleming has this dispatch on new findings that are being revealed by ancient sources. Archaeologists are looking at ancient DNA combined with oral histories to determine ecological conditions from the past.  By Whitney Fleming […]

How herring learn from their elders

Young Pacific herring (Clupea pallasii) learn migration behavior by joining up with older fish, according to a new paper co-authored by Puget Sound Institute Lead Ecosystem Ecologist Tessa Francis. The paper, published this month in the ICES Journal of Marine Science, showed how this behavior leads to greater spatial variability in biomass, and that commercial […]

New Puget Sound herring research

Herring may not be the most charismatic species in Puget Sound. They don’t breach dramatically out of the water. Fish mongers don’t throw them through the air at Pike Place Market. They find their strength in numbers, schooling around by the thousands and serving as food for other creatures like seabirds, salmon and seals. But […]
