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 …
By Jeff Rice, Puget Sound Institute A strong economy driven by a world-leading technology industry is expected to draw millions of new residents to the Salish Sea region within decades. This changing population brings with it new strains on the environment but also new perspectives. Incoming residents may not see Puget Sound the same way …
In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. This month, PSI senior writer Christopher Dunagan looks at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask. Read the article …
Concerns are growing that an earthquake or major ship accident could cause a failure that would halt ship traffic — or, worse, drop water levels in Lake Washington and Lake Union by up to 20 feet. That could mean stranded boats, disabled bridges and big problems for salmon restoration. Read the story in Salish Sea …
They are sometimes called ‘zombie’ chemicals. Some compounds thought to be safe and inactive can change into dangerously active forms when they are exposed to the environment. Two recent papers co-authored by PSI collaborator Ed Kolodziej look at some of the ways that regulators may need to account for these transformations. Cole, EA, McBride, SA, Kimbrough, KC, Lee, J, Marchand, …
Our Director Joel Baker recently co-authored Microplastics in the Ocean: A Global Assessment, an international report commissioned by GESAMP (The Joint Group of Experts on Scientific Aspects of Marine Environmental Protection). GESAMP is an inter-Agency Body of the United Nations, comprised of a group of independent scientists providing advice to UN Agencies on a wide variety of …
Every year, winter rains bring the threat of millions of dollars in property damage, or even the loss of life, from floods. Rivers have historically been channeled and tamed to protect towns and farms in low-lying floodplains, but research shows that this approach may actually be making flooding worse while at the same time threatening …
The decaying seawall along Seattle’s waterfront is providing scientists with an opportunity to improve long-lost habitat for migrating salmon. It could also show the way for habitat enhancements to crumbling infrastructure worldwide. One University of Washington researcher describes the project. Read more about the Seattle seawall in Salish Sea Currents.
One of the goals set by the state’s Puget Sound Action Agenda is to add 20 percent more eelgrass to the region by 2020. But three years into the effort, there’s been little or no progress, and growing perplexity. Studies show that some eelgrass beds are increasing while others are in decline. Scientists met at …
Puget Sound Institute research scientist Tessa Francis testified before the Washington House Environment Committee today about the ecological importance of the region’s forage fish. She discussed findings from PSI’s recent Study Panel on Ecosystem-based Management of Forage Fish in Puget Sound. Watch the testimony online.
The current cold snap is no match for the green roof at PSI headquarters. Our own Kurt Marx has been monitoring roof conditions here at the Center for Urban Waters and gave us this graphic showing temperatures about 5 degrees Celsius warmer under the surface. Read more about the LEED Platinum Center for Urban Waters. Related item: …
Social media now proliferates across almost every sector of the Web, from commercial enterprises like Facebook to crowd sourcing of science and medical data. New online communities are sprouting like weeds, but not all of these efforts succeed, and the Web is littered with failed attempts and false starts. How can you tell if your …
