In August, PSI Director of Special Projects Michael Kern was invited by the University Network for Collaborative Governance (UNCG) to discuss the research questions driving the Collaborative Leadership Project at the UNCG Scholarship Retreat. The retreat was held at the University of Wyoming’s AMK Ranch in Grand Teton National Park. It was attended by about […]

Two new baby orcas with no deaths over the past year could make for a remarkable census
This year’s census for the Southern Resident killer whales apparently will document two new calves but no deaths for the 12-month period ending July 1. According to my unconfirmed records, this will be the first time in nearly 30 years that no deaths will be reported in the annual census update. Consequently, the overall population […]

Salish Sea Model tracks pollution, currents and climate change
This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. Today, we look at the Salish Sea Model, one of several models in the region helping to predict water circulation, water quality and food-web relationships. Read the full series: Where and how the water moves The […]

Prey and predators create varying life-or-death conditions for salmon, as shown with Atlantis model
This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. As scientists uncover more and more information about a particular ecosystem, computer modelers are often eager to put that raw data to good use in complex models tuned to local conditions. One highly acclaimed model, called […]

Examining the link between low summer stream flows and climate
A 2023 paper in the Journal of the American Water Resources Association says future low flows in Puget Sound streams could be lower than are projected by climate models that do not reliably account for multidecadal climate variation. The paper is co-authored by Nicholas Georgiadis and Joel Baker of the Puget Sound Institute. When rains […]

Wastewater fee study reveals hardship for low-income households
Low-income households may need financial help to address the impact of rising wastewater bills, according to a study of current and projected sewage treatment costs published last month by the Puget Sound Institute. The study was initiated in support of the Marine Water Quality Implementation Strategy, a state and federal recovery plan addressing water pollution […]

Southeast Alaska troll fishing restored for this year by court of appeals pending full legal review
Fishing in Southeast Alaska by the commercial troll-fishing fleet will not be cancelled this year, as ordered by a Seattle judge, thanks to a last-minute ruling by the U.S. Ninth Circuit Court of Appeals. Considerations for the economic damage that would be caused by shutting down the Alaskan fishery outweigh the “speculative environmental threats” that […]

Quantitative models, including Ecopath, take food web studies to a higher level of analysis
As part of a project exploring the technical uncertainties surrounding Puget Sound water quality, we are reviewing how computer models are used to advance our understanding of natural systems. This blog post is part of a series focused on different models and their uses within the Puget Sound ecosystem. The project is jointly sponsored by King […]

New federal and state funding to study toxics in Puget Sound
The Puget Sound Institute (PSI) and its parent organization the Center for Urban Waters (CUW) are the recipients of more than $3.2 million dollars in grants this month from the Environmental Protection Agency and the Puget Sound Partnership. The funds will go toward understanding and reducing emerging threats from toxic chemicals in Puget Sound. The […]
