Salish Sea snapshots: Detecting harmful algal blooms

Environmental samplers may provide early detection of harmful algal blooms (HABs) in Puget Sound. This toxic algae is expected to increase as the climate changes, bringing with it new and potentially more severe outbreaks of shellfish poisonings.

Marine bird science in Puget Sound

Birds serve as useful indicators of ecosystem change and ecosystem health, biodiversity, condition of habitats, and climate change. Many people and organizations have their eyes on marine birds in Puget Sound.

Advances in technology help researchers evaluate threatened Puget Sound steelhead

New, smaller acoustic tags will allow scientists to track steelhead migrations in Puget Sound in ways that were once impossible. Will they provide answers to the mysterious decline of these now-threatened fish?

Eyes Over Puget Sound: Surface Conditions Report – June 27, 2016

Record-breaking warmer and fresher water in Puget Sound. May-June conditions are more unusual than last year. Recent rain brought river flows close to normal but water exchange in Puget Sound remains weak due to low Fraser River flow. Phytoplankton blooms and organic material are visible in some areas of Central and South Sound but not in others. Noctiluca, while absent in Central Basin, was

Key hypotheses include bottom-up and top-down processes and additional factors such as toxics, disease, and competition.  Graphic: Michael Schmidt, Salish Sea Marine Survival Project

Mystery remains in deaths of young salmon

The Salish Sea Marine Survival Project has mobilized dozens of organizations in the U.S. and Canada to find an answer to one of the region's greatest mysteries. What is killing so many young salmon before they can return home to spawn? A series of talks at the 2016 Salish Sea Ecosystem Conference brought together some of the latest research.

Contaminants higher in resident 'blackmouth' Chinook

Many of Puget Sound's Chinook salmon spend their entire lives in local waters and don't migrate to the open ocean. These fish tend to collect more contaminants in their bodies because of the sound's relatively high levels of pollution. 

Protecting Puget Sound watersheds from agricultural pollution using a progressive manure application risk management (ARM) system

Throughout the Puget Sound region, impacted and poorly managed agriculture has been repeatedly advanced as a leading contributor to surface and ground water pollution, particularly during the winter months. A study conducted from 2010 - 2015 aimed to develop an Application Risk Management (ARM) System to minimize pollution from manure in Whatcom County. 

Snohomish Basin Protection Plan

A 2015 report from Snohomish County, King County and the Tulalip Tribes outlines protection strategies for salmon and salmon habitat within the Snohomish Basin.

Salish Sea 'slime' vital for shorebirds

It turns out that a gooey substance known as biofilm is a big deal for Salish Sea shorebirds, providing critical food for some species. But could a proposed port expansion in Vancouver threaten this slimy resource?
