A series of 10 workshops on the subject will begin Tuesday, July 26th, and continue into next year. The workshops, coordinated by the Puget Sound Institute, will build on previous discussions, such as the Washington Department of Ecology’s Nutrient Forum and a forthcoming Marine Water Quality Implementation Strategy that […]

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

Share

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 low-oxygen conditions. What is needed now, some argue, is a stronger regionwide consensus around solutions to the problem. That could mean coming to terms with research findings, understanding the strengths and weaknesses of the models, […]

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

Share

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 the official census. For K pod, this is the first confirmed calf to be born since 2011. The youngster was first reported on April 28 by a fishing guide cruising off the Oregon Coast. The […]

Series of workshops will advance understanding of nutrients in Puget Sound

Share

Our region is navigating complex and challenging decisions on how best to manage nitrogen, dissolved oxygen, and the potential impacts of eutrophication on the key habitats and species of the Salish Sea. Over the next year, the Puget Sound Institute is sponsoring a series of scientific workshops to help address technical uncertainties and to advance modeling tools to assist decision-making related to nutrient pollution and broader water quality challenges. Supported by King County and municipalities in the Puget Sound Clean Water Alliance, we are collaborating to: Facilitate 10 scientific workshops with […]

Green crabs in Hood Canal raise questions about invasion; further response is coming

Share

For the past six years, a volunteer crew has been diligently visiting Nick’s Lagoon near Seabeck on Hood Canal, checking the waters for the destructive European green crab. The three citizen scientists have caught and released lots of native crabs — including thousands of hairy shore crabs. But, until May of this year, they never saw even one invasive green crab, known for its potential disruption of shellfish beds and destruction of native habitat. The discovery of a green crab in Central Hood Canal was fairly shocking for those involved. […]
