The 12th U.S. Symposium on Harmful Algae will be held on Oct. 27-Nov. 1, 2024 at Holiday Inn Portland by the Bay in Portland, Maine.

Logo by Hannah Bonner, Utah Department of Environmental Quality

The theme, ONE BLOOM, seeks to identify and highlight commonalities across diverse study systems and disciplines within Harmful Algal Bloom (HAB) research. Sessions and discussions will foster a unified understanding that integrates perspectives and approaches in HAB science, and equips researchers, managers, and policymakers with the knowledge needed to address this pressing environmental challenge.

The symposium is open to all registrants. Attendees include national representatives and researchers from academia; state, federal, tribal, and municipal governments; the private sector; and watershed organizations.

Symposium Program

Pre-Conference Workshops (click on a workshop to expand)

Workshop A – Development of a Regional Poison Control Center and Medical Toxicology Guideline for Harmful Algal Bloom Sample Collection and Testing Pathways: A Pilot Study

Sunday, October 27 | 10:30-11:30am | $15

Brett Johnson, UMass Chan School of Medicine, UMass Medical Center

Reports of human poisoning from harmful algal blooms (HABs) in the US are infrequent compared to other foodborne illnesses. This is likely due to successful state-level surveillance programs and underreporting by healthcare providers (HCPs) who often do not recognize toxin-mediated poisoning syndromes. The US experience with HAB health events typically follows regional patterns, correlating to algal species endemic to specific areas, with some cases linked to interstate seafood commerce. HCPs must be vigilant in diagnosing and treating potential poisoning after seafood consumption, despite the lack of readily available confirmatory testing, which requires assistance from local public health departments and historically relies on testing food matrices. Current treatment practices are largely based on case reports, and there is no consensus on human specimen analysis.

This workshop aims to engage key stakeholders in developing effective response and management strategies for HAB-related illnesses. Collaborative discussions will guide the creation of region-specific guidelines for poison control centers and medical toxicology programs on sample collection and testing based on available medical evidence.

Workshop B – Data to Information: A Look at the HABs Data Housed in the Water Quality Portal and Served Through How’s My Waterway

Sunday, October 27 | 10:30-11:30am | $15

Adam Griggs, US EPA

Join us for a comprehensive workshop on the Water Quality Portal (WQP), the premier source for discrete water-quality data in the United States and beyond. The WQP integrates publicly available data from the United States Geological Survey (USGS), Environmental Protection Agency (EPA), and over 1,500 state, federal, Tribal, and local agencies. This collaborative service compiles extensive physical, chemical, and biological water-quality data. The workshop will feature a demonstration of an innovative application designed to explore harmful algal blooms (HABs) data within the WQP. Participants will learn how to access and utilize over 3 million Chlorophyll records, as well as hundreds of thousands of algal taxa counts and toxin samples. The session will also cover how to effectively use the data from the WQP and How’s My Waterway to support water quality monitoring and research. This workshop is ideal for environmental professionals, researchers, and anyone interested in leveraging comprehensive water-quality data for better resource management and public health protection.

Workshop C – Demonstrating a Novel Molecular Toolbox for Rapid, Sensitive Detection of Toxic Pseudo-nitzschia Species

Sunday, October 27 | 1:00-3:00pm | $30

Matthew Harke, Gloucester Marine Genomics Institute, Inc (GMGI); Kate Hubbard, FWC-FWRI; Pete Countway, Bigelow; Shelly Wanamaker, GMGI; Taylor Gibson, GMGI; Sydney Greenlee, Bigelow; Yida Gao, FWC-FWRI; Robin Sleith, Bigelow; Alex DeSmidt, FWC-FWRI; Camden Conte, FWC-FWRI; Julie Koester, FWC-FWRI

The pennate diatom Pseudo-nitzschia produces the neurotoxin domoic acid (DA) which can impact both humans and marine wildlife when consumed. Over 50 species have been identified globally, and DA production varies both across and within species with myriad potential triggers now recognized. DA is an emergent threat in the Gulf of Maine (GOM) and Gulf of Mexico (GOMx) and has led to shellfish harvest closures over the last decade, with each region associated with distinct Pseudo-nitzschia species. Monitoring programs typically enumerate cells using light microscopy, however toxic and non-toxic Pseudo-nitzschia spp. often coexist and cannot be discriminated without electron microscopy and/or genetic methods. Given that Pseudo-nitzschia blooms are observed in these areas with emergent DA issues, and that DA levels can change rapidly, there is a clear need for rapid detection and quantification of toxic Pseudo-nitzschia species. In this workshop, as part of an ongoing MERHAB funded project, we invite you to join us as we demonstrate several novel portable molecular methods for rapid detection of toxic Pseudo-nitzschia species appropriate for diverse end-users, including state managers.

Workshop D – Track, Identify, Predict: An Introduction to 3 Complementary HAB Monitoring Systems

Sunday, October 27 | 1:00-4:00pm | $30

Savannah Judge, Yokogawa Fluid Imaging Technologies, Inc.; Chris Lee, AquaRealTime; Greg Ford, Phytoxigene

Freshwater cyanobacteria and some marine dinoflagellates and diatoms have the potential to produce harmful toxins that cause adverse health effects in humans and animals. Monitoring is essential for effective natural resource management and public safety. However, many monitoring approaches exist from total biomass, to organism identification, to toxin testing. This workshop will demystify this matrix by offering practical skills in three early-detection HAB systems that provide different yet complementary information: an online multi-parameter measuring & reporting system (AlgaeTracker), an automated flow-imaging microscope (FlowCam), and a quantitative PCR assay (CyanoDTec/DinoDTec). The workshop will begin with an overview of each technology, followed by hands-on demonstrations. Attention will be given to how these technologies are utilized in freshwater versus marine environments.


Special Sessions

Meet the Funders: A Quick Tour of Federal Funding Programs for HAB Science and Management

Tuesday, October 29 | 7:00-9:00pm | Free

Sarah Pease, NOAA

Anika Dzierlenga, NIH/NIEHS; Mandy Michalsen, USACE; Whitney King, EPA; Jennifer Graham, USGS; Taylor Armstrong, USHCTI; Sarah Pease, HAB-ER; Maggie Broadwater, ECOHAB; Marc Suddleson, MERHAB; Felix Martinez, PCMHAB; Brittany King, SEAHAB; Tiffany Vance, IOOS; Betty Staugler, Sea Grant

Join NOAA’s National Centers for Coastal Ocean Science (NCCOS) Competitive Research Program (CRP) for a two-hour workshop aimed at demystifying federal funding opportunities for harmful algal bloom (HAB) research, response, and management. Participants will learn about various HAB-related federal funding programs and priorities across agencies such as EPA, NIEHS, NOAA, USACE, and USGS. The workshop seeks to provide equitable access to information, making HAB funding more accessible to academic, non-academic, tribal, and community-based researchers, as well as resource management agencies. The workshop will include brief overviews of funding programs, followed by a matchmaker-style event where participants can engage in small group discussions with program managers. This interactive approach will help attendees identify which federal funding programs best fit their needs, align their applications with program priorities, and increase their chances of obtaining funding. This workshop is ideal for early career researchers and resource managers looking to enhance their understanding of the federal funding landscape for HAB research and response activities.
