Eyes Over Puget Sound: A Decade in Review

The Washington State Department of Ecology has reached one hundred Eyes Over Puget Sound reports. Since 2011, Ecology has provided aerial observations and documented visible features at the surface of Puget Sound from a floatplane. This unique perspective from the air featured Puget Sound's natural beauty, its oceanographic complexity, and its ecological treasures. It also raised awareness of the challenges that the water body is facing today. Our image-rich documentation of known eutrophication indicators ranges from algal and Noctiluca blooms to macroalgae, jellyfish, and human stressors. It provides a visually captivating time-capsule of issues facing Puget Sound. The report is rich in educational and outreach material, inspired numerous news reports, and drew academic and public attention during the period of marine heat wave of the north Pacific, The Blob.

Eyes Over Puget Sound: Surface Conditions Report - October 2022

The report comes after a third year of La Nina conditions. Weak upwelling off the coast and low river flows of major rivers meant less cold, nutrient-rich, upwelled water was being entrained into Puget Sound in late summer and fall. Water conditions in Puget Sound in October were generally expected while Willapa Bay and Grays Harbor were both unusually warm and salty. Smoky air restricted our flight to Southern Puget and Central Sound where we saw blooms in terminal bays as well as patches of jellyfish. Sediment in Commencement Bay and along shorelines in Totten Inlet was unusual for a dry fall. A healthy foodweb has at its base a balance of nutrients. Explore what we found over the period of two decades of monitoring.

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 an 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 essential role to a great diversity of sea life in Puget Sound, phytoplankton can also contribute to low-oxygen conditions, and some can be harmful in other ways.

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 says, with the mixing of fresh and salt water and something called the estuarine exchange flow.

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.

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.

Bird populations improve after Elwha Dam removals

Dam removals are often associated with salmon recovery, but new research on the Elwha River suggests that birds also benefit. Scientists say birds are a sometimes-overlooked indicator of river health.

Four years after Tahlequah's journey, the legal and ethical debates over orca protection continue to evolve

It has been four summers since a mother orca’s dramatic vigil brought worldwide attention to the plight of Puget Sound’s southern resident killer whales. A recent gathering of legal experts, conservationists, and academic scholars looked at how perceptions of the whales have changed since then and whether laws and policies should reflect new thinking about ethical responsibilities to orcas and other animals.

Eyes Over Puget Sound: Surface Conditions Report - March to June 2022

Low air temperatures, rain, and late snow accumulation pushed back the discharge of meltwater to Puget Sound this season. The water temperature in Puget Sound was mostly at expected levels, but cooler in South Sound by May. Central Sound saw more oxygenated conditions. This year, La Niña weather made flying for aerial photography challenging, but by June, sunny days made up for it, revealing a high number of schooling fish, unusually low tides, and a glimpse of macroalgae to come. Internal waves in Central Basin and Puget Sound, and the beauty of Puget Sound from the air, are a reminder of the unique place we live in.

Eyes Under Puget Sound: Critter of the Month - Catworms

With their square heads and antennae that look a bit like pointy ears, it makes sense why the catworms, or marine segmented worms in the family Nephtyidae, would be named after cats. But their antennae are more like a cat’s sensory whiskers than ears, allowing them to feel their way through the mud as they crawl and burrow. Nephtyids are strong diggers, and can even hold their own in the water, rapidly wiggling their smooth, pale bodies in order to swim.

Eyes Under Puget Sound

The Washington State Department of Ecology’s Marine Sediment Monitoring Program, initiated in 1989, is one component of the Puget Sound Ecosystem Monitoring Program, a collaborative effort dedicated to monitoring environmental conditions in Puget Sound. The Marine Sediment Monitoring Team collects sediments from the bottom of Puget Sound twice a year and tests them to determine their physical, chemical, and biogeochemical characteristics; and to determine the condition of the invertebrate communities that live in them.  They report their findings in agency reports and story maps, and in Eyes Under Puget Sound (EUPS) blog posts.

Lamprey legacy: Eel-like fish return after dam removal

Prehistoric-looking lamprey are recolonizing parts of the Elwha River that they have not occupied for more than 100 years. Like salmon, the culturally and ecologically important fish also move from saltwater into rivers to spawn. And like salmon, lamprey were devastated by the dams that once blocked their way. We conclude our series 'Returning home: The Elwha's genetic legacy.'

Good news for bull trout in the Elwha

Bull trout appear to be thriving in nearly every section of the Elwha River. Populations there have at least doubled in the years since dam removal, signaling good news for a species that has struggled throughout the West.

Returning home: The Elwha's genetic legacy

Following dam removal, migratory salmon have been free to swim into the upper Elwha River for the first time in 100 years. Their actual behaviors and reproductive success may well be driven by changes in their genetic makeup. Our seven-part series 'Returning home' examines how the fish are doing and whether the Elwha's genetic legacy remains intact.

Wild steelhead still a force in the Elwha

Migration patterns have apparently reawakened for the Elwha River's wild steelhead. Studies show that the fish may have retained much of their genetic drive despite 100 years of being trapped behind dams. We continue our series 'Returning home: The Elwha's genetic legacy' with part two of seven.

Placing microphones on orcas offers a point-of-whale perspective on underwater noise

Research on the sounds and feeding behavior of Puget Sound's southern resident orcas is providing new insight into how the whales respond to underwater noise. A recent online conference brought together some of these findings along with discussions on how to reduce the impacts of noise from vessel traffic.
