Salish Sea Model tracks pollution, currents and climate change

Share

This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. Today, we look at the Salish Sea Model, one of several models in the region helping to predict water circulation, water quality and food-web relationships. Read the full series: Where and how the water moves The waters of Puget Sound contain complex chemical mixtures arising from natural and human sources. The waters are blended and pushed around by currents and other physical forces, creating conditions that vary from place to place. […]

Modeling “the blob” in the Salish Sea

In late 2013, a marine heatwave that scientists dubbed “the blob” began warming the ocean throughout the Northeast Pacific, causing temperatures to rise almost 3°C above normal. The disruption severely depressed salmon returns. Whales, sea lions and seabirds starved, and warm water creatures were suddenly being spotted off the coast of Alaska. In Puget Sound, temperatures also jumped, but the effects of the blob here proved difficult to study because of the natural variability of the Salish Sea and the heavy influence of freshwater mixing and circulation in the waterbody. Recently, computer simulations from our partners at the Salish Sea Modeling […]

The Puget Sound Institute is launching a new program that will use supercomputers to advance ecosystem recovery of the Salish Sea. The Salish Sea Modeling Center will allow scientists from around the region to access sophisticated computer models to predict changes in the ecosystem. Work at the center will tackle vexing environmental problems such as the changing chemistry of the Salish Sea and other mysteries puzzling scientists. The center is supported by the Environmental Protection Agency and other regional water quality partners. If you want to understand where fish or […]
