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 […]

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 […]

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 […]

Symposium grapples with long-lasting PCBs
Researchers at the Puget Sound Institute hosted a two-day symposium last month to share information about the science and management of PCBs in the environment. The online workshops, held January 24th and 25th, were organized by PSI researchers Andy James, Joel Baker, and Marielle Larson, in coordination with colleagues Will Hobbs (Washington State Department of […]

Remembering Ken Balcomb and his extraordinary life with killer whales
I’m still adjusting to the world of killer whales without Ken Balcomb. Ken, who died Dec. 15 at age 82, was a constant presence throughout my career as an environmental reporter. His presence inspired many others among the so-called “killer whale community,” made of experts, observers and those who simply love and follow the stories […]

The quest continues for a nutrient reduction plan
The quest continues for a large-scale plan to reduce human sources of nitrogen and improve the health of Puget Sound. This article is part of the Puget Sound Institute’s effort to explore the technical uncertainties related to the science of Puget Sound water quality. The project, jointly funded by King County and PSI, includes online […]

A network of computer models is predicting the future of Puget Sound
A new $4.8 million dollar project led by the Puget Sound Institute links together a series of computer models to explore future scenarios across the watershed. Some of Puget Sound’s biggest concerns hold the greatest uncertainties. Will we have clean water? Can the ecosystem sustain species like endangered salmon? How can the region continue to […]

As winter approaches, salmon and orcas are still a commanding presence
With salmon and orcas still on the move and facing ever-changing weather conditions, I thought it might be time for a brief update to my blog post of Nov. 21. At the time of the last report, the Puget Sound region had gone through a 13-day dry spell, which followed a period of brief and […]
