The bivalve-rich beaches of Hood Canal were all summer after detection of a marine biotoxin that causes , a life-threatening foodborne illness that affects the nervous system.

Given that Washington’s commercial shellfish industry employs nearly 2,400 people and brings in more than $240 million each year, a monthslong closure during peak season had sweeping consequences.

Detecting harmful algal blooms early is critical for consumer safety and trust in the industry. The Washington State Department of Health oversees a that monitors toxin levels in shellfish tissue from various growing areas. The effort is supported by an unofficial partner: , a program launched by National Oceanic and Atmospheric Administration in 2006 that migrated to Washington Sea Grant several years later.

Unlike the DOH, SoundToxins screens the water for harmful algae, which can expedite detection. When SoundToxins monitors detected   — a species of phytoplankton that produces the toxin that causes PSP — they quickly relayed the information to the DOH, which closed the impacted marine areas before anyone got sick.

Although this type of advance warning can save lives, the future funding of the program is uncertain. Washington Sea Grant relies on a patchwork of research grants and federal and state funds to operate SoundToxins. Recent cuts to research funding and the current state of Washington’s budget have illuminated the precariousness of funding for vital programs like this. Washington Sea Grant remains committed to working with state and federal partners to find the right funding pathway to keep SoundToxins running.

A quantified the value of SoundToxins with survey data. UW News spoke with program manager about the results and the program.

How is the monitoring program and the early detection of harmful algal blooms (HABs) valuable?

Michelle Lepori-Bui: Harmful algal blooms can be really detrimental to the shellfish industry as closures have a direct impact on revenue and because recalls and illnesses affect the reputation of shellfish as a safe and healthy food source. Robust monitoring programs and early warning of these events help protect public health and minimize these impacts. There are many benefits to early detection of HABs to the general public and recreational and commercial harvesters that can be hard to quantify. Farmers can benefit by modifying harvesting activities to minimize losses, avoiding recalls, and maintaining trust in the market, while shellfish consumers and coastal communities benefit from safe local food sources and working waterfronts.

How does the new study demonstrate the value of SoundToxins?

MLB: This survey sought to capture the many tangible and intangible benefits of the program and distill them into a single economic metric using an approach called ‘willingness to pay.’ The study found that shellfish growers value the program with a willingness to pay $533/year for phytoplankton monitoring. With changing environmental conditions, shellfish mortality events, and heat waves, growers are facing an extremely challenging production environment. The finding that they are willing to pay this amount, even during these challenging economic times, shows how valuable this program is to coastal communities.

How does SoundToxins support the state-led effort?

MLB: The DOH’s biotoxin monitoring program is a series of steps in compliance with the National Shellfish Sanitation Program that starts with monitoring for biotoxins in mussel tissue. Mussels typically pick up toxins faster than other species, so they are a good indicator, but other species are tested as well. If toxins are detected, they can initiate recreational and commercial closures.

We’re not part of the official regulatory process, but our work can guide the DOH’s efforts through early warning. We maintain a database populated with volunteer data and a map that uses red, yellow and green color coding to report HAB presence on the coast and in Puget Sound and surrounding waters. We notify the DOH via email when something changes and it uses that information to prioritize certain samples or request additional samples.

Who collects the data?

MLB: SoundToxins is a very cost-effective program because we have really amazing monitors, partners and volunteers. A lot of different folks do the actual monitoring. We work with tribes, growers, environmental education groups and individuals at 35 different sites throughout the region. We provide them with equipment and training and support the database, and they collect and analyze the samples, posting everything online within 24 hours.

What happened this summer? How was it different from years past?

MLB: We got an alert from our monitor in early June that they found Alexandrium cells in a sample from Hoodsport, which is pretty far south in Hood Canal. That alert went straight to the DOH and it reacted quickly, requesting more samples from various parts of Hood Canal.

Historically, there haven’t been many incidents of PSP in south Hood Canal. There were a few blooms in the early 2000s and a big bloom in 2015 that went further south than usual, close to Hoodsport but not to the end of Hood Canal. That was considered unprecedented and this year surpassed that.

It’s understood globally that harmful algal blooms are increasing in frequency, severity and impact. This is partially related to changing climate conditions. Also, phytoplankton like Alexandrium respond to nutrients in the water. The input of nutrients from human activities can influence blooms. We have seen things showing up in places they haven’t been before and increasing in intensity.

A lot of people are working on models to predict harmful algal blooms, but it’s complicated, especially in our area where there are a lot of complex water bodies. We need to continue doing the research to try to understand things better, but in the meantime, monitoring is critical.

Bloomberg recognizes UW Tech Policy Lab as ‘Top Legal Innovation Program’

The UW Tech Policy Lab was recently recognized by Bloomberg as a in 2022 due to its unique cross-discipline approach. The award is given to pioneering schools making an impact in the legal field.

Founded in 2013 by faculty from the UW School of Law, the Paul G. Allen School of Computer Science & Engineering and the Information School, the lab bridges the gap between technologists and policymakers to help generate wiser, more inclusive tech policy.

“The students and community members who interact with the lab come away with the understanding that collaborating and bringing a variety of perspectives together is the key to working through contemporary challenges,” said , professor of law at the UW and co-director of the Tech Policy Lab. Bloomberg’s Law School Innovation Program seeks to recognize and connect law school faculty, staff and administrators who are education innovators. Submissions to the program were scored based on impact on students, ability to advance the legal industry and replicability. In its submission, the UW Tech Lab demonstrated the model’s unique blend of immersive experiences, opportunities for relationship-building and interdisciplinary approaches.

“Rather than try to work with every student, we offer programming open to all and work closely with a small handful of law students whom we place on interdisciplinary teams to work on consequential issues of tech policy,” Calo said. “They often go on to work in the field and get a unique perspective and experience working across disciplines.”

This was the inaugural year of the awards.

UW professor wins 2023 Seattle Aquarium Conservation Research Award

Vera Trainer, affiliate professor of aquatic and fishery sciences at the UW, was selected as the winner for her work on harmful algal blooms, or HABs, which are proliferations of algae that cause environmental and economic damage.

The Conversation Research Award has honored leaders and innovators in marine conservation research since 2004, focusing on climate change, plastic pollution, sustainable fisheries and tourism, marine protected areas and socioeconomics.

“This award is not only for what has been accomplished, but what will be accomplished in the future,” said Trainer, a former NOAA oceanographer and current research lead for the .

Trainer’s HABs research has provided a foundation for understanding the effects climate change has had on coastal ecosystems and highlights the need for inclusion of impacted communities in decision-making.

Trainer is also co-founder of the program and founder of , a partnership that monitors HABs in the Puget Sound. These unique community collaborations provide advance warning of HABs that threaten seafood safety as well as ecosystem and human health, ultimately ensuring safe, sustainable shellfish harvests.

Astronomy professor awarded for stellar physics textbook

The American Astronomy Society awarded , associate professor of astronomy at the UW, and her co-author Henny J.G.L.M.ĚýLamers the for their graduate textbook “Understanding Stellar Evolution.”

The Chambliss Award recognizes astronomy writing geared towards the upper-division undergraduate or graduate level, a rarely recognized category.

“It’s great to see the importance of stellar physics recognized,” said Levesque. “Henny Lamers spent more than a decade developing amazing lecture notes for our course on stellar structure and evolution, and it was great to work with him on turning these into a textbook.”

Split into three parts, the book first delves into the physics of how stars work. It then describes the evolution of stars from formation to death and explores some complicating factors of stellar evolution. The book was produced using years of lecture notes for an astronomy class at the UW.

“We spent a lot of time expanding and fleshing out roughly outlined ideas from lecture notes so that they could stand alone as complete explanations in the textbook,” said Levesque. “It was interesting to be teaching the course and writing the book at the same time in the spring of 2016. It helped alert us to a topic or detail that would spark discussion or follow-up questions in class and encouraged us to expand on the topic in the text.”
