New project searches for contaminants of emerging concern

PSI research scientist Andy James has been funded by the Environmental Protection Agency’s National Estuary Program to identify contaminants of emerging concern (CECs) in the waters of Puget Sound. There are literally thousands of man-made chemicals known as CECs circulating in local waters, but very little is known about their impacts on wildlife. They are …

Detecting organic contaminants in highway runoff and fish tissue

This much we know: Stormwater is nasty stuff. The state of Washington has called it one of the leading threats to the Puget Sound ecosystem — it can kill salmon within hours and it contributes to all kinds of health problems for species ranging from orcas to humans. What we don’t know is exactly what’s …

Increasing adult mortality in Puget Sound herring may contribute to population declines

PSI’s lead ecosystem ecologist Tessa Francis is co-author of a 2017 paper linking increasing adult mortality of Puget Sound herring with regional population declines in the species. The authors report that natural mortality among herring four years and older has doubled in Puget Sound since 1973, suggesting a possible connection to declines at spawning sites …

Implementation strategies will target Puget Sound ‘Vital Signs’

When a scientist wades into an eelgrass bed or measures the weight of a Chinook salmon, their connection to the environment is clear. Much of what we know as the ‘scientific process’ takes place on the ground at a local scale. Measurements and observations are made and extrapolated. Scientists get their feet wet. But what …

A comparative study of human well-being indicators across three Puget Sound regions

Puget Sound Institute social scientist Kelly Biedenweg has published a comparative study of three well-being indicators in the Puget Sound region. The article appears in the August issue of the journal Society & Natural Resources. Abstract: Simple frameworks that generalize the best metrics of human well- being related to the natural environment have rarely been empirically …

‘Inside Radiolab’ will interview PSI Director and other Puget Sound area panelists

Our Director Joel Baker is part of a panel of four environmental leaders in Puget Sound who will be interviewed onstage at the Inside Radiolab show next week in Tacoma. Radiolab’s Robert Krulwich will host the January 22nd event at the Pantages Theater where he will interview panelists about Northwest water issues. In addition to …

Wastewater study looks at Seattle marijuana use

One of our collaborators made news this week for his pilot study quantifying marijuana use in Seattle and Tacoma. Dan Burgard, a chemist at the University of Puget Sound, is analyzing wastewater from sewage treatment plants to identify levels of metabolized THC. The study is designed to determine if new recreational marijuana laws are leading to an increase in marijuana …

Ocean Modeling Forum to hold Pacific Herring Summit June 8-10

Puget Sound Institute lead ecologist Tessa Francis is co-chair of an upcoming summit to examine the human dimensions of Pacific herring fisheries in the Salish Sea. The forum brings together “social and natural scientists, tribes and First Nations, and federal and state managers” to identify new approaches to ecosystem-based management, including the use of traditional ecologic knowledge …
