Eyes on the Elwha: A Conversation with WSG Coastal Hazards Specialist, Ian Miller

March 3, 2025

By Maddie Gard, WSG Science Communications Fellow

When the Elwha River dams were breached in 2011, a century’s worth of accumulated sediment was released and transported downstream to the coastal zone. An estimated 19 million metric tons of mud, sand and gravel that had been trapped in the dam reservoirs transformed twists and turns of the Elwha River, eventually flushing out to the coast and reshaping the river delta near Port Angeles. Since then, Washington ...

Protocol in Focus: Why do we measure native crabs, too?

June 18, 2024

Why Measure Native Species?

When it comes to interactions between crabs, whether of the same species or of differing species, size matters. When crabs run into each other out on tide flats, in lagoons, or channels, they might compete for food or shelter, or they may actually try to prey on each other. In these encounters, the general rule of #CrabLife is that bigger crabs win over smaller crabs. So knowing the size of not only green ...
