Scientists, Partners and the Public Prioritize Marine Resources of Washington’s Olympic Coast

In preparation for future management and research investments, scientists from NOAA’s National Centers for Coastal Ocean Science and the Office of National Marine Sanctuaries are collecting information from regional stakeholders and members of the public regarding Washington’s Olympic Coast.  Objectives are to assess the social value of coastal and marine resources, and to determine regional […]

Common Coastal Seaweeds Release Toxins Harmful to Marine Organisms

A new study has found that compounds excreted by common coastal green seaweeds, or sea lettuce, detrimentally affect other organisms. The green seaweed Ulvaria obscura forms blooms in the intertidal and subtidal zones. During high spring tides, this seaweed strands on the shore and succumbs to drying, high levels of sunlight, and high temperatures. These […]

Puget Sound Stakeholders See Value in HAB Forecasts

At a June 26 meeting, NCCOS-funded ECOHAB project investigators concluded that climate change could increase the window of opportunity for blooms of the toxic dinoflagellate, Alexandrium catenella to occur. In light of this information, state officials expressed strong interest in seasonal HAB forecasts, while industry and local managers requested daily to weekly forecasts. Although future climate change will […]

Enhanced Monitoring Saved Puget Sound Net Pen Salmon Threatened by Extreme Harmful Algal Bloom

In June, the straits, bays and islands of Puget Sound experienced some of the most extensive harmful algal blooms (HABs) in recent memory, including at least five potential toxin producers. Blooms of Heterosigma akashiwo, which causes massive fish kills, were widespread and threatened the salmon net pen mariculture industry. Enhanced HAB monitoring in the area led […]

Origins of Harmful Alga Scourge in Pacific Northwest Confirmed

Researchers have identified the oceanographic causes and routes for the harmful alga Pseudo-nitzschia in offshore waters of the Pacific Northwest. The team’s validated model shows that toxic Pseudo-nitzschia cells arrive at the coast, not from a single source (as previously thought), but from two sources, one north and one south of Washington’s beaches. The northern source […]

NCCOS Researchers to Assist Washington State in Marine Planning

NCCOS scientists traveled to Washington State May 13-17 to support marine planning along the outer Pacific coast. NCCOS is helping inventory and assess key seafloor, groundfish, seabird and marine mammal datasets essential to effective marine planning. They are developing a data viewer that will help the state, other coastal managers, and researchers visualize seafloor datasets, […]

NCCOS HAB Partner Honored by White House

On June 25, NCCOS HAB Program partner Dr. Julia K. Parrish was honored as a Champion of Change by the White House.  Dr. Parrish is the founder and executive director of the Coastal Observation and Seabird Survey Team (COASST), a group that organizes coastal residents to monitor beach-cast seabird carcasses in California, Oregon, Washington and […]

NCCOS-funded Science in Washington State Seeks to Better Understand Linkages Between HAB Cysts, Shellfish Toxicity, and Threshold for HABs

In March, the Puget Sound Alexandrium Harmful Algal Bloom (PS-AHAB) Project (funded by The National Centers for Coastal Ocean Science‘s Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) Program) issued the 2013 preliminary Alexandrium cyst map. This is part of PS-AHAB’s “just-in-time” information dissemination program to Puget Sound stakeholders to increase early warning capabilities for HAB events. Highest cyst […]
