Tiny plankton play a mighty role in the health of Puget Sound

Diverse communities of microscopic organisms called phytoplankton make up the base of the aquatic food web. In that role, they are essential to the tiny animals that eat them, but phytoplankton are not dependent on others. Thanks to chlorophyl, these tiny organisms can generate their own energy from nutrients and sunlight. Despite their critical importance to a great diversity of sea life in Puget

What drives Puget Sound's 'underwater Amazon'?

In a new series we are calling Ask a Scientist we interview local researchers to get their thoughts on some of the important but lesser-known scientific facts about the Puget Sound ecosystem. Today, we speak with University of Washington oceanographer Parker MacCready about Puget Sound’s “underwater Amazon” and why it has profound implications for Puget Sound science and policy. It all begins, he

Eyes Under Puget Sound: Critter of the Month - Ghost Shrimp

Fall’s chill is in the air (finally!), leaves are turning colors, and skeletons and spider webs are popping up in yards all over town. Meanwhile, under the mud of Puget Sound, there’s a strange critter that stays in its ethereal costume all year long – the burrowing ghost shrimp.

Whir! Chunk! Capture! The art of tagging rhinoceros auklets on Protection Island

Where do Protection Island's rhinoceros auklets go to find their food? Scientists hope GPS tags will offer new insight into the bird's still mysterious foraging behavior. Biologist and science writer Eric Wagner reports from the field.

Study raises questions about using ‘woody debris’ to restore streams

A new report says further study may reveal why experts cannot find expected benefits to salmon populations, despite widespread use of wood in stream restorations.

Notes from the field: The Illusion of abundance

Biologist and science writer Eric Wagner recently returned from a trip to observe pigeon guillemots on Protection Island. He wonders: How much do we really know about the health of seemingly abundant bird populations?

An eye on harbor seals

Occasionally, our magazine includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Biologist and author Eric Wagner has this look at an ongoing harbor seal survey at the mouth of the Stillaguamish River. Wagner says the study hinges on a basic question: Who is eating the salmon?

First modern clam garden takes shape in Puget Sound

The Swinomish Indian Tribal Community has begun constructing the first known clam garden to be built in modern times. They hope that what was once an ancient way of cultivating shellfish can now be a hedge against climate change.
