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 […]

West Coast Harmful Algal Bloom Observing System Design Paper Published

A recently published research paper describes the minimum requirements for an effective harmful algal bloom (HAB) observing system for the U.S. west coast to mitigate HAB impacts.  HAB observing systems provide early warning and forecasting of HAB events to guide decisions to close shellfish harvesting to protect human health, avoid mortality of protected species, and encourage aquaculture […]

Research Paper Documents History, Impacts of West Coast Harmful Algae Species

A recent research paper presents the state-of-knowledge on harmful algae along the west coast of North America. Along the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) are responsible for losses to natural resources and coastal economies, and have sickened and killed humans and animals for decades. Recent reports indicate […]

New Algal Threat to Puget Shellfish Eaters Draws Event Response Funding

The National Centers for Coastal Ocean Science provided funds so that the state of Washington’s Department of Health, the NOAA Northwest Fisheries Science Center HAB Program, and the  SoundToxins partnership can analyze diarretic shellfish poisoning (DSP) toxins in shellfish and monitor for Dinophysis, the dinoflagellate that produces the toxins. In 2011 three people became ill with DSP […]

Algae Monitoring Protects Oregon Recreational Shellfish Gatherers–For Now

On July 6th, the Oregon Department of Agriculture (ODA) and the Oregon Department of Fish and Wildlife (ODFW) announced the closure of recreational mussel harvesting for over 120 miles of Oregon Coast from Tillamook Head south to Heceta Head due to elevated levels of paralytic shellfish toxins (PST).  The closure includes mussels found on the […]

Puget Sound Toxic Algae Forecast Moves Closer to Reality

On May 31, investigators funded by the National Centers for Coastal Ocean Science released the second annual map of Alexandrium catenella cysts in bottom sediments throughout Puget Sound in the state of Washington. They found that the highest cyst concentrations at Bellingham Bay in the north and Quartermaster Harbor in the south, similar to 2011. This year’s cyst abundance in the […]

Research Promotes Method to Slow the Spread of Encrusting Invasive Species

Dredging channels and cleaning boat hulls or fishing gear in or near established Didemnum colonies can create fragments of these invasive organisms that survive in the water column up to four weeks, disperse long distances, and even reproduce before resettling, possibly in new areas, according to NOAA research. The article suggests that cleaning equipment on land and reducing bottom disturbance […]
