LiveOcean: Pacific Northwest ocean and estuary forecasts

LiveOcean is a computer model simulating ocean water properties in Puget Sound and the Pacific Northwest. It is produced by the University of Washington Ocean Modeling Group and makes three-day forecasts of currents, temperature, salinity and many biogeochemical fields including harmful algal blooms.

Projected sea level rise for Washington State

A 2018 report from the Washington Coastal Resilience Project provides an updated assessment of projected sea level change for coastal Washington State and its relationship to coastal hazards such as flooding and erosion. 

Puget Sound River History Project

The Puget Sound River History Project at the University of Washington features historical topographic data for Puget Sound's river systems.  

The impacts of rogue chemicals on Puget Sound

In early 2016, scientists at NOAA made headlines when they reported finding 81 different man-made chemicals in the tissues of juvenile Chinook salmon in Puget Sound. Among those chemicals were drugs such as cocaine and Prozac.

This was the first time scientists had made these findings for the region’s salmon, but it was already well-understood that local waters — and marine waters the world over — are becoming an alphabet soup of rogue chemicals. In varying degrees, these chemicals are settling into the bodies of every species analyzed in Puget Sound, including humans.

Removing Puget Sound's Great Wall

Can we really wait 700 years to remove all of the armoring along Puget Sound's shoreline? Let's do some of the math.

Second invasive green crab found in Puget Sound

Last month, EoPS senior writer Christopher Dunagan's series on invasive species in Puget Sound highlighted some of the state's worries about the arrival of the European green crab. The article noted that "the threat could be just around the corner." It could not have been more timely.

Clam hunger: environmental impacts on food and well-being

A story this week in Salish Sea Currents delves into the connection between environmental change and culturally important foods. Writer Sarah DeWeerdt interviewed social scientists at the 2016 Salish Sea Ecosystem Conference about how this affects the spiritual and physical health of Salish Sea tribes and first nations. “The loss of subsistence and cultural identity cannot be estimated,” Joe Schumacker of the Quinault Department of Fisheries told her.

Tracking the secret lives of forage fish

Some of the most important fish in the Salish Sea food web are also the most mysterious. Researchers have only begun to understand how many there are, where they go, and how we can preserve their populations for the future. University of Washington graduate student Margaret Siple describes how scientists are looking into the problem in the latest issue of Salish Sea Currents

Coming this week in Salish Sea Currents: Invasive stowaways threaten Puget Sound ecosystem

Invasive species are among the three greatest threats to the environment worldwide, according to the International Union for Conservation of Nature. Species ranging from microscopic viruses to larger creatures like rodents and non-native fish can alter the balance of entire ecosystems. The threat is well-known in Puget Sound and the Salish Sea, which face their own unique challenges.

Studies show connections between food supply and orca reproduction

Chances are, if you think about the Puget Sound ecosystem, you will think at some point about orcas. There may be no more striking image than an orca breaching against the backdrop of Mount Rainier, or a family of whales slicing through the waters of the San Juans. The fact that there are so few resident orcas remaining — less than a hundred Sound-wide — is part of their mystique. When they experienced a mini 'baby boom' this year, it was celebrated in the media and noted as a positive sign by scientists.
