A Primer to Living Shorelines Published

A synthesis of recent thinking and results from practitioners and researchers of Living Shorelines just hit the stands. “Living Shorelines: The Science and Management of Nature-Based Coastal Protection,” details many aspects of the shoreline stabilization approach, and specifically includes: (1) background: history and evolution; (2) management, policy, and design; (3) synthesis of Living Shoreline science: physical […]

Work Begins to Assess Emerging Algal Toxin Threat in Washington State Waters

In early June 2016, NOAA and Washington State partners begin a four-month long effort to monitor shellfish and water every week at six locations around Puget Sound and on the Pacific coast. The team plans to measure concentrations of marine algae and their associated lipophilic (fat soluble) toxins, which can accumulate in shellfish and cause […]

Puget Sound Water Quality Review Highlights NCCOS HAB Research

The Puget Sound Ecosystem Monitoring Program released the 4th annual report on marine water conditions in Puget Sound for 2014 on September 9, 2015. The report, “Puget Sound Marine Waters: 2014 Overview,” enhances the understanding of the complex ecosystem of Puget Sound, an economic lifeline for Western Washington. The comprehensive report covers a host of […]

Harmful Algal Cyst Mapping in Washington Shows 10-fold Increase since 2013

An unprecedented bloom of the harmful alga Alexandrium occurred during Fall 2014 in Quilcene Bay, Hood Canal, Puget Sound, WA; the outbreak contaminated shellfish with potent biotoxins that can cause paralytic shellfish poisoning. The area of the bloom was historically biotoxin free, but at the peak of the event, the Washington State Department of Health detected toxin […]

Puget Sound Harmful Algal Blooms Linked to Seasonal Patterns and Survival Probability

In order to predict blooms and prevent undue economic loss of commercial shellfish in Puget Sound, NCCOS has sponsored research investigating the seasonal patterns and mechanisms of bloom formation of Alexandrium, a dinoflagellate that contaminates shellfish and causes paralytic shellfish poisoning (PSP) in humans. The study shows Alexandrium survives and spreads in Puget Sound in response to […]

NCCOS, Partners Improve Aquaculture Siting and Production in Puget Sound

NCCOS and partners are using computer modeling to determine the carrying capacity for shellfish aquaculture—and the related potential for nutrient removal—in South Puget Sound. The team’s methodologies and guidelines will be used to inform marine spatial planning activities locally and throughout the U.S., promoting sustainable shellfish aquaculture and providing a framework for addressing issues that commonly lead […]

The Craib Corer: Predicting Harmful Algal Blooms by Sampling the Seafloor

Forecasting harmful algal blooms is a complex endeavor involving a wide range of oceanographic disciplines. NCCOS scientists and sponsored researchers count the number of harmful algal bloom (HAB) resting stages or cysts that lie on the bottom of the ocean as one method to estimate the future occurrence of HABs. Scientists use a suite of […]

Assessing Future Harmful Algal Bloom Risk for Washington State

In Puget Sound, the toxic alga Alexandrium catenella threatens the health of people who eat shellfish contaminated with toxins it produces. An NCCOS Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project, Puget Sound Alexandrium Harmful Algal Blooms, annually mapped “seedbeds” of Alexandrium resting stages (cysts) at about 100 locations on the bottom throughout Puget Sound. The project […]
