Mindy Roberts of Washington Conservation Action said someone asked her a few years ago about the frequent sewage spills occurring in Tacoma’s Thea Foss Waterway. “My answer was, ‘What sewage spills?’” Mindy recalled, quickly realizing that if she didn’t know about sewage spills in her own city, then hardly anybody else was likely to know […]

After five rounds of voting, the winner of the Grand Uncertainties Madness tournament bracket is: What type of protection and restoration actions have the largest and most lasting impact on floodplain function and which types of actions are cost effective? This research need (from the rivers group) won in a close but decisive victory over […]

When out on Puget Sound with killer whale experts, I’m often impressed by how quickly such folks can identify individual whales by name or number, even when a group of orcas is swimming a fair distance away. I can’t begin to do that, because I have never studied the catalogs of dorsal fins and markings […]

An external scientific review by independent experts is a common and valuable practice, particularly when the models have significant management implications. This ethos is why peer review is foundational to science in general. By providing an objective assessment, external reviewers can help ensure the models are robust and appropriate for the management decisions they’re being […]

You might have noticed that the Encyclopedia of Puget Sound looks especially awesome these days. We just released EoPS 2.0 with more vibrant colors, improved navigation and more modern features under the hood. You’ll still find the same great articles, but they will load a little faster and will play well with new browsers and smartphones. Take […]

Culminating more than a decade of fierce debate, Washington state officials formally adopted new water-quality standards for toxic chemicals to protect the health of people who eat fish from our local waterways. On its face, this action appears inconsequential, considering that these numerical criteria were already in place, having been imposed two years ago by […]

In a natural state, a river passing through a floodplain will have many side channels and tendrils that distribute the water, fanning it out across the delta. However, these channels are often lost when rivers are diverted to make room for farmland or other human development. In many cases, even after the dikes and levees […]

This past summer, two science papers documented, for the first time, the presence of two species of sharks not known to exist in Puget Sound. These species are commonly called sevengill and soupfin sharks. I am sorry to say that I did not know much about sharks in Puget Sound, and I had never written […]

Southern Resident killer whales have been hanging out in Puget Sound much longer than normal this fall, probably because of an unusually large run of chum salmon coming into Central and South Puget Sound, experts say. As of today, J pod has remained in Puget Sound for 19 straight days with the exception of a […]
