More HABs information is available on EPA's CvanoHABs in Water Bodies website Occurrence and Effects of Harmful Algal Blooms in Fish and Shellfish A webinar hosted by U.S. EPA, Office of Water, Office of Science and Technology March 22nd 2022 from 12:00 - 4:00 PM ET 11 AM - 3 PM CT110 AM-2 PM MT 9 AM-1PM PT On March 22, 2022, EPA's Office of Science and Technology hosted a webinar on the Occurrence and Effects of Harmful Algal Blooms in Fish and Shellfish to share information on the occurrence and impacts of HABs in fresh and marine fish and shellfish, and to learn about ways to protect human health and the environment from the risks of HABs and their toxins. The webinar was well attended by representatives from states, tribes, territories, federal agencies, universities, and international governments. Topics covered included: • freshwater impacts with presentations from the University of Geneva, California EPA, the Big Valley Band of Pomo Indians, EPA Office of Research and Development; and • estuarine and marine impacts with presentations from National Oceanic and Atmostpheric Administration; the French Agency for Food, Environmental and Occupational Health Safety; and the Northwest Indian College. Each presentation was followed with a question and answer session. Presentations and a recording of the webinar are posted to the webinar webpage of the EPA CyanoHABs website. ------- NEWS ON HABs New USGS Publication on Mapping Benthic Algae and Cyanobacteria in River Channels The U.S. Geological Survey's (USGS) National Water Quality Program recently published a report resulting from a partnership with the National Park Service that evaluates the feasibility of mapping benthic algae via remote sensing. In the report, titled Mapping Benthic Algae and Cyanobacteria in River Channels from Aerial Photographs and Satellite Images: A Proof-of-Concept Investigation on the Buffalo National River, AR, USA, scientists describe the use of aerial photographs and satellite images to classify four levels of algal density along the Buffalo National River in Arkansas. For more information, contact Carl Legleiter at cjl@usgs.gov Interstate Technology and Regulatory Council (ITRC) NEW Training Courses for Harmful Cyanobacterial Blooms (HCBs) ITRC published a new Benthic Harmful Cyanobacteria Blooms (HCB-2) Guidance Document addressing the unique challenges of evaluating and communicating to the public the health and environmental risks of benthic HCBs, and providing contemporary best management practices for this type of harmful bloom. ITRC's HCB Team will be hosting live Internet-based training sessions about this new guidance document and two training courses on HCBs. Registration is now open. • April 26, 2022 (Tuesday) - Strategies for Preventing and Managing Harmful Cyanobacterial Blooms (HCBs) - a course covering cyanobacterial blooms in general, with a focus on planktonic blooms. • April 28, 2022 (Thursday) - Harmful Cyanobacterial Blooms (HCBs) - Benthic - a new course focused primarily on benthic HCBs. Webinars Series Indian River Lagoon (IRL) Council GeoCollaborate: Informing Harmful Algal Bloom Emergency Response Four webinars will be held to explore datasets associated with the 2016 HAB and fish kill events in the Indian River Lagoon, Florida. Speakers will describe emergency response scenarios and illustrate the use of GeoCollaborate to communicate and coordinate a regional emergency response. Speakers will include: • Duane De Freese PhD., Executive Director, Indian River Lagoon Council and National Estuary Program • Charles Jacoby PhD., Supervising Environmental Scientist, St. John's River Water Management District • Kirsten Jo Ayres, GIS Coordinator, Indian River Lagoon Council and National Estuary Program • Dave Jones, CEO/Founder, StormCenter Communications, Inc.

National HAB Observing Network Community of Practice (NHABON CoP) Call for Members of the Steering Committee The Steering Committee of the NHABON CoP is soliciting nominations or self-nominations for new members. Read the NHABON CoP Terms of Reference to learn more about the CoP, the roles and responsibilities of steering committee members, and the selection criteria. To nominate someone for consideration, please fill out this form, and submit a resume to maggie@ioosassociation.org by Friday, April 29, 2022. The Steering Committee expects to meet monthly to plan quarterly webinars as well as additional activities to foster scientific collaboration, information sharing, and other activities. Such activities aim to lead to the development, operation, and application of the NHABON at local, state, and regional levels. 2 ------- Reported Blooms, Beach Closures, and Health Advisories* - March 2022 *lncludes blooms, cautions, warnings, public health advisories, closings, and detections over state thresholds due to the presence of algae and/or toxins.
