In some cases, vast stretches of open water become hypoxic, or low in oxygen. Unable to sustain life, these areas, called dead zones, may cause die-offs of fish, shellfish, corals, and aquatic plants.
The Salish Sea Model is used to predict spatial and temporal patterns in the Salish Sea related to factors such as phytoplankton, nutrients and Dissolved Oxygen. It is a collaborative effort between the Pacific Northwest National Lab, the Washington State Department of Ecology and U.S. Environmental Protection Agency.
The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Overview this week. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.
An algal bloom is a rapid increase or accumulation in the population of algae in a water system. While most are innocuous, there are a small number of algae species that produce harmful toxins to humans and animals.
Decaying organic matter plays an important role in marine ecosystems.
A report from NOAA and the Puget Sound Ecosystem Monitoring Program provides an overview of 2014 marine water quality and conditions in Puget Sound from comprehensive monitoring and observing programs.
The Puget Sound Update is a technical report that integrates results of PSAMP and other scientific activities in Puget Sound focused on marine life and nearshore habitat, marine and freshwater quality, and toxic contamination.
A report from the Puget Sound Ecosystem Monitoring Program provides an overview of 2013 marine water quality and conditions in Puget Sound from comprehensive monitoring and observing programs.
The Puget Sound Model was designed and built in the early 1950s at the University of Washington School of Oceanography as a research and teaching tool for understanding Puget Sound circulation patterns. The following text was written by Puget Sound Model co-creator John H. Lincoln (1915-2001) and is provided courtesy of the University of Washington School of Oceanography.
The 2013 State of the Sound is the Puget Sound Partnership’s third report to the Legislature on progress toward the recovery of Puget Sound by 2020. The document reports on both the status of the Partnership's recovery efforts and the status of a suite of ecosystem indicators.
The Puget Sound Marine Waters 2012 Overview from the Puget Sound Ecosystem Monitoring Program synthesizes conditions measured in 2012 and has been expanded to include observations on seabirds that rely on marine waters. Read an excerpt below, or download the full report.
The 2013 Health of the Salish Sea Ecosystem Report was prepared jointly by the U.S. Environmental Protection Agency and Environment Canada. View the complete report, or read the Executive Summary below.
The Washington Department of Ecology distributes a monthly report combining high resolution aerial photographs with satellite and ground-truthed monitoring data for Puget Sound surface conditions.
There are at least 28 species of rockfish in the Salish Sea, but their populations have declined in the past several decades. The proceedings from a 2011 rockfish recovery workshop in Seattle are now available.
An independent review conducted by the Puget Sound Institute (PSI) is featured in findings by the Environmental Protection Agency and the Washington State Department of Ecology that there is currently “no compelling evidence” that humans are the cause for recent trends in declines in dissolved oxygen in Hood Canal.
The Puget Sound Marine Waters 2011 report is now available. The report was produced by the Puget Sound Ecosystem Monitoring Program and assesses the condition and quality of the waters of Puget Sound.
