Soundtoxins: A Puget Sound Harmful Algae Monitoring Partnership, Teri King, Lyndsey Claassen, Jerry Borchert, Vera Trainer Apr 2018

Soundtoxins: A Puget Sound Harmful Algae Monitoring Partnership, Teri King, Lyndsey Claassen, Jerry Borchert, Vera Trainer

Salish Sea Ecosystem Conference

SoundToxins is a diverse partnership of aquaculture businesses, federal, tribal, state, and local governments, education institutions, and Puget Sound residents that monitor for harmful algae in Puget Sound, managed by NOAA’s Northwest Fisheries Science Center and Washington Sea Grant. The intensively trained partners provide early warning of harmful algal bloom (HAB) events by evaluating water samples gathered weekly from 35 stations throughout Puget Sound looking specifically for Dinophysis, Alexandrium, Pseudo-nitschia and Azadinium and alerting health and natural resource agencies of their presence and concentration. The online database and mapping allows for near-real time viewing of data entered by SoundToxins partners …

Reanalysis Of Continuous Shellfish Monitoring Data In Pursuit Of Temporal And Spatial Patterns Of Paralytic Shellfish Toxins In The Puget Sound/Salish Sea, Margaret L. Taylor, Erika Mcphee-Shaw, Stephanie K. Moore, Cheryl Greengrove Apr 2018

Reanalysis Of Continuous Shellfish Monitoring Data In Pursuit Of Temporal And Spatial Patterns Of Paralytic Shellfish Toxins In The Puget Sound/Salish Sea, Margaret L. Taylor, Erika Mcphee-Shaw, Stephanie K. Moore, Cheryl Greengrove

Salish Sea Ecosystem Conference

Harmful algal blooms (HABs) are of growing concern on the West Coast of North America. The dinoflagellate Alexandrium catanella is known to produce toxins that have the potential to concentrate in shellfish and, when consumed by humans or marine mammals, may result in Paralytic Shellfish Poisoning (PSP) leading to illness or death. In Puget Sound, the Washington State Department of Health (WDOH) collects and tests shellfish samples to protect the health and safety of shellfish consumers as well as the livelihood of the extensive local shellfish industry. Such data have been collected since the 1950s. We analyze data from 2003 …

Comparison Of Alexandrium Spp. Surface Sediment Cyst Maps From Quartermaster Harbor In 2007 And 2017, Cheryl Greengrove, Julie Masura, Thanh-Thuy Nguyen, Mitchell Schatz

Salish Sea Ecosystem Conference

Quartermaster Harbor (QMH), in central Puget Sound, has historically been a hotspot for the occurrence of the toxic dinoflagellate Alexandrium spp. and associated summer shellfish bed closures. Alexandrium spp. overwinters as cysts in the sediment and germinates into swimming vegetative cells during the summer when conditions are right. Alexandrium spp. produces neurotoxins which can be concentrated in the tissue of filter-feeding shellfish, which in turn can be fatal to humans if ingested. In 2005, the first Puget Sound wide surface sediment cyst mapping survey found QMH to have the highest concentration of Alexandrium spp. cysts in the sound. A more …


Assessing Harmful Algal Bloom Risk In Puget Sound: A Coupled Modeling-Data Analysis Approach, D. L. Woodruff, Taiping Wang, Stephanie K. Moore, Zhaoqing Yang, Ning Sun, Jerry Borchert, Audrey Coyne, Guillaume Mauger, Valerie Cullinan Apr 2018

Assessing Harmful Algal Bloom Risk In Puget Sound: A Coupled Modeling-Data Analysis Approach, D. L. Woodruff, Taiping Wang, Stephanie K. Moore, Zhaoqing Yang, Ning Sun, Jerry Borchert, Audrey Coyne, Guillaume Mauger, Valerie Cullinan

Salish Sea Ecosystem Conference

The increased frequency, duration and geographic extent of toxic Alexandrium blooms in Puget Sound presents new challenges of how to best allocate resources available for toxin monitoring of shellfish in order to protect human health. Monitoring plans are typically based on shellfish toxicity patterns from the recent past; however, the increasing trend in Alexandrium blooms means that managers are chasing a moving target. With projected future changes in global and regional climate, the risk of toxic Alexandrium blooms is expected to increase. Through funding from NOAA’s Coastal and Ocean Climate Applications Program, we are developing a harmful algal bloom (HAB) …
