The debate over oxygen in Puget Sound

A draft nutrient reduction plan from the Washington Department of Ecology is out for public review. Now, many new developments — technical, scientific and legal — are reaching a critical stage and setting up a framework to make some major decisions. This four-part series in Our Water Ways looks back on how we have reached our present condition, including a consideration of possible solutions.

Follow the herring: Why sea lions have been calling Shilshole Marina home

For the past three springs, Shilshole Bay Marina has been contending with droves of California visitors occupying their guest boater moorages––California sea lions that is. To Shelby Allman, Port of Seattle Harbor Operations Supervisor, it seemed like the furry visitors arrived almost overnight. By mid-May nearly 120 animals had hauled themselves onto five “finger” docks […]

July 8 roundtable will dig into assessing effects of multiple climate change stressors on marine invertebrates and developing mitigation techniques to minimize impacts

Co-hosted with Fisheries and Oceans Canada (DFO) Climate change is leading to increasingly warmer oceans that are also more acidic, less oxygenated, and with lower salinity (among other changes). The resultant impacts on marine organisms will depend on the rate, level, and variability of change of individual stressors and how effectively the animals can deal […]

Unpacking uncertainty: How experts recommend improving Puget Sound modeling

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 […]
