"> Health of killer whales examined through Bayesian network modeling and informed predictions
Qualitative network modeling, as shown in the previous post in Our Water Ways, is focused on actions that create either positive or negative results for actors in the model. This modeling approach is useful for considering the possible outcomes triggered by various actions, especially when data are lacking to develop mathematical relationships between the actors. […]

"> Researchers use a qualitative network model to test ways to boost production at shellfish farms
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 […]

"> Shutdown looms for Alaska summer troll fishery; court order aims to provide more salmon for orcas
Southern Resident killer whales, which frequent Puget Sound, are expected to benefit from more Chinook salmon later this year, as expressed in a court order calling for the suspension of a major troll fishery in Southeast Alaska. Alaska state officials are dismayed by the ruling, saying that closing this commercial fishery would have a devastating […]

"> A tale of two islands
By Eric Wagner Science is hard, but coming up with a title for a scientific paper is harder. Exhibit A: the paper some colleagues and I recently published in Marine Ecology Progress Series. Originally I wanted to call it, “A Tale of Two Islands: Disparate Responses to a Marine Heatwave at Two Pacific Seabird Colonies.” […]

"> Inbreeding hinders population recovery among endangered Southern Resident killer whales
While a scarcity of Chinook salmon and other environmental factors may be pushing the Southern Resident killer whales toward extinction, a new genetics study has revealed that inbreeding has been exerting a powerful, overriding influence upon the small, genetically isolated population. The weakened genetic condition of the Southern Resident orcas, which frequent Puget Sound, could […]

"> Findings and reports: February 2023
Salish Sea Model provides insights on circulation and residence times The amount of time water circulates and “resides” in Puget Sound is of intense interest to regulators and emergency response officials who want to understand how quickly wastewater is flushed out of Puget Sound and into the ocean. A paper in the journal Estuarine, Coastal […]

"> PUGET SOS brings new funding and a federal makeover
Recently passed federal legislation has increased funding to protect Puget Sound while also changing the way ecosystem recovery efforts are organized. The legislation includes key provisions of the PUGET SOS Act and establishes a national office for Puget Sound recovery based at the Environmental Protection Agency in Seattle. The end of 2022 marked a seismic […]
