Does Puget Sound need a diet?

As the region’s population grows, scientists say we can expect to see increasing amounts of nitrogen and other elements flowing into Puget Sound. Known as “nutrients” these elements are naturally occurring and even necessary for life, but officials worry that nutrients from wastewater and other human sources are tipping the balance. That could mean big […]

They find their strength in numbers, schooling around by the thousands and serving as food for other creatures like seabirds, salmon and seals. But […]

Dispatches: Herring rescue

A Puget Sound scientist’s work is never done. PSI’s Lead Ecosystem Ecologist Tessa Francis sent us this e-mail about a recent call to identify some wayward fish on Vashon Island. It didn’t hurt that she happens to study the same species of fish — Pacific herring — as part of her research at PSI. By Tessa […]

Study looks at climate change impacts on zooplankton

PSI’s Lead Ecosystem Ecologist Tessa Francis is co-author of a paper describing the impacts of climate change on freshwater zooplankton communities. The 2017 paper in the journal Climate Change Responses analyzes plankton communities in an Alaskan lake and predicts that some copepods in the study area will decline while other plankton such as cladocerans will […]

Ocean Acidification: From Knowledge to Action - Washington State's Strategic Response (report cover)

Local actions highlight ocean acidification report

By Christopher Dunagan, Puget Sound Institute The dangers of ocean acidification — an intrinsic feature of climate change — are coming early to Washington state, causing measurable harm to sea life, according to a new report that outlines a state strategy for pushing back against the problem. The report, titled “Ocean Acidification: from knowledge to […]
