Modeling

Many types and classes of models have been developed and applied to parts or all of the Salish Sea ecosystem including efforts to model impacts of climate change, assess the implications of alternative urban growth patterns and understand water circulation patterns and nutrient loading. Models in this case can refer to physical or mathematical representations of the ecosystem or components of the ecosystem including human impacts.

OVERVIEW

The Salish Sea Model

The Salish Sea Model is a computer model used to predict spatial and temporal patterns related to water circulation in the Salish Sea. It was developed at the United States Department of Energy's Pacific Northwest National Laboratory with funding from the Environmental Protection Agency. It is housed at the University of Washington Puget Sound Institute.

Salish Sea Model looks at climate impacts on the nearshore

A 2019 paper in the Journal of Geophysical Research: Oceans outlines how the Salish Sea Model describes the impacts of climate change, sea level rise and nutrient loads on the region's nearshore environment.

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.

Videos: The Puget Sound Model

The Puget Sound Model was designed and built by the University of Washington School of Oceanography in the early 1950s to simulate the tides and currents of Puget Sound. A series of videos produced by the Encyclopedia of Puget Sound describes its construction and operation.

Ecosystem models expand our understanding of the Salish Sea

Scientists are using computer models to address complex issues in the Salish Sea like the rise of harmful algal blooms and the movement of toxic PCBs. LiveOcean, Atlantis and the Salish Sea Model are three systems that are changing the game for ecologists and other researchers.
