Killer whale miscarriages linked to low food supply

New techniques for studying orcas have been credited with breakthroughs in reproductive and developmental research. Drones and dogs are helping scientists connect declines in food supply with low birth rates and poor health.

Salish Sea snapshots: Detecting harmful algal blooms

New technology may provide early detection of harmful algal blooms in Puget Sound. This toxic algae is expected to increase as the climate changes, bringing with it new and potentially more severe outbreaks of shellfish poisonings.

Marine bird science in Puget Sound

Birds serve as useful indicators of ecosystem change and ecosystem health, biodiversity, condition of habitats, and climate change. Many people and organizations have their eyes on marine birds in Puget Sound.

Advances in technology help researchers evaluate threatened Puget Sound steelhead

New, smaller acoustic tags will allow scientists to track steelhead migrations in Puget Sound in ways that were once impossible. Will this new technology provide answers to the mysterious decline of these now-threatened fish? 

Key hypotheses include bottom-up and top-down processes and additional factors such as toxics, disease, and competition.  Graphic: Michael Schmidt, Salish Sea Marine Survival Project

Mystery remains in deaths of young salmon

The Salish Sea Marine Survival Project has mobilized dozens of organizations in the U.S. and Canada to find an answer to one of the region's greatest mysteries. What is killing so many young salmon before they can return home to spawn? A series of talks at the 2016 Salish Sea Ecosystem Conference brought together some of the latest research.

Contaminants higher in resident 'blackmouth' chinook

Many of Puget Sound's chinook salmon spend their entire lives in local waters and don't migrate to the open ocean. These fish tend to collect more contaminants in their bodies because of the sound's relatively high levels of pollution.

Protecting Puget Sound watersheds from agricultural pollution using a progressive manure application risk management (ARM) system

Throughout the Puget Sound region, impacted and poorly managed agriculture has been repeatedly advanced as a leading contributor to surface and ground water pollution, particularly during the winter months. A study conducted from 2010 - 2015 aimed to develop an Application Risk Management (ARM) System to minimize pollution from manure in Whatcom County.

Salish Sea 'slime' vital for shorebirds

It turns out that a gooey substance known as biofilm is a big deal for Salish Sea shorebirds, providing critical food for some species. But could a proposed port expansion in Vancouver threaten this slimy resource?

New theory rethinks spread of PCBs and other toxics in Puget Sound

Researchers are proposing a shift in thinking about how some of the region’s most damaging pollutants enter Puget Sound species like herring, salmon and orcas.

Researchers are studying how persistent pollutants such as PCBs avoid settling to the bottom of Puget Sound. This article continues our coverage of new theories on the spread of toxic chemicals in the food web.

Gearing up for the 2016 Salish Sea Ecosystem Conference

About 4,600 miles of coastline wind from southern Puget Sound to northern British Columbia along what is known as the Salish Sea. It is a land of connections and contradictions. Snowmelt from three national parks feeds more than a thousand creeks and rivers that in turn flow to the rich floodplains and estuaries of places like the Skagit and Nisqually Delta. It is one of the most diverse and spectacular ecosystems  in the world, a fact made even more incredible because it is also home to 8 million people.

State guidelines offer new approaches to shoreline protection

Bulkhead removal is becoming an attractive option for many shoreline property owners as awareness spreads of their geological and ecological impacts, and as aging bulkheads come up for replacement. New state guidelines provide alternatives to hard armor.

Sources of sand: maps show crucial “feeder bluffs”

For more than a hundred years, property owners have seen shoreline erosion as the enemy. But it turns out that in many cases erosion is actually a good thing — crucial, according to scientists — because it provides the sand and gravel needed for healthy beaches.

Studies point to gap in permits for shoreline armoring

A significant number of Puget Sound property owners have been altering their shorelines without required permits. A new report suggests that state and local regulators should increase enforcement and make penalties more costly for violators.

Shoreline restoration turns to private property owners

By removing bulkheads where they can, property owners are improving shoreline habitat, one piece at a time. Officials from county and nonprofit groups have been offering assistance and finding new ways to connect with property owners.

Shoreline armoring's effect on the food web

The removal of shoreline armoring in Puget Sound has become a priority for state and federal agencies, but until recently there have been relatively few scientific studies of armoring's local impact. New research looks at the pronounced biological and ecological effects of these common shoreline structures, especially for tiny beach-dwelling creatures that make up the base of the food web.
