Six things that people should know about ecosystem modeling and virtual experiments

The Puget Sound Institute is facilitating a series of online workshops and discussions to explore the technical uncertainties related to the science of Puget Sound water quality. As part of the project, we are publishing informational blogs and articles, including this look at how computer models are becoming increasingly important to our understanding of the natural world. The project is …

Add-on structure will begin to address steelhead crisis at the Hood Canal Bridge

The Hood Canal Bridge, which connects the Kitsap and Olympic peninsulas, has proven to be a dangerous impediment to juvenile steelhead trout. As many as half of the young migratory steelhead in Hood Canal may get picked off by seals, birds and other predators as the fish try to pass under the floating highway, according …

Low-oxygen problems to be scrutinized in talks about research, modeling efforts

By Christopher Dunagan For decades, researchers have been advancing their understanding of what causes the harmful and sometimes deadly low-oxygen problems afflicting some areas of Puget Sound. Computer models have been developed to replicate conditions and point the way to possible solutions. Experts generally agree that excess nitrogen flowing into Puget Sound contributes to the …

New orca calf confirmed amid serious health concerns and actions to protect the whales

A surprise visit by K pod on Saturday near Vancouver Island led to the official confirmation of a new orca calf born into the Southern Resident killer whale community. The new calf, designated K45, is the second baby born to the Southern Residents this year, as recorded by the Center for Whale Research, which maintains …

Recent papers from our group: 6PPD-Q updates and the ongoing hunt for contaminants

New papers this month 6PPD-Quinone: Revised Toxicity Assessment and Quantification with a Commercial Standard A 2022 article in the journal Environmental Science & Technology Letters revises previous findings on the environmental concentration and toxicity of 6PPD-Quinone, a novel compound lethal to coho salmon. The paper reports that 6PPD-Quinone, a chemical resulting from tire wear particles, …

North Pacific expedition gets underway aboard four ocean-going research ships

A North Pacific research expedition is underway, with projects said to be bigger, bolder and more scientifically sophisticated than cruises in 2019 and 2020. Four research vessels carrying more than 60 scientists from various countries will span out across the Pacific Ocean to increase their understanding of salmon — including migration, environmental stresses, availability of …

Understanding the cold-water needs of salmon and helping them to survive

Salmon need cold water. This general statement is something I’ve been hearing since I first began reporting on these amazing migrating fish years ago. Cold water is a fact of life for salmon, known for their long travels up and down streams, out to saltwater and back. But colder is not always better. Questions about …

Recovery of Puget Sound species could hinge on better understanding of ecosystems

A recent report from the Puget Sound Partnership helps us understand the difficulty of restoring the Puget Sound ecosystem. What caught my attention in the State of the Sound report was that after 20 years of protecting and restoring streams, wetlands, shorelines and estuaries, we have not increased overall fish and wildlife populations, and some …
