This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. As scientists uncover more and more information about a particular ecosystem, computer modelers are often eager to put that raw data to good use in complex models tuned to local conditions. One highly acclaimed model, called Atlantis, has been applied to more than 40 ecosystems around the world. In Puget Sound, Atlantis has been used to study the food web to determine whether salmon are more threatened by predators or by […]

Quantitative models, including Ecopath, take food web studies to a higher level of analysis

As part of a project exploring the technical uncertainties surrounding Puget Sound water quality, we are reviewing how computer models are used to advance our understanding of natural systems. This blog post is part of a series focused on different models and their uses within the Puget Sound ecosystem. The project is jointly sponsored by King County and the Puget Sound Institute. In the early 1980s, NOAA scientist Jeffrey Polovina and fellow researchers at the National Marine Fisheries Service in Hawaii developed what they called the Ecopath model, designed to describe […]

The Puget Sound Institute is facilitating a series of online workshops and discussions to explore the technical uncertainties related to the science of Puget Sound water quality. As part of the project, we are publishing informational blogs and articles, including this look at how computer models are becoming increasingly important to our understanding of the natural world. The project is jointly sponsored by King County and the Puget Sound Institute. By Christopher Dunagan If you are planning a hike, picnic or other outdoor activity, it might be wise to take a look at the local […]
