  • The NHABON Community of Practice (CoP) is creating a Steering Committee! Read the NHABON CoP Terms of Reference here to learn more about the community, the roles and responsibilities of steering committee members, and the selection criteria. To nominate yourself or someone else for consideration, please fill out this form, and submit a resume to maggie@ioosassociation.org by Friday, April 29 2022. Current members of the Steering Committee include Quay Dortch (NOAA NCCOS, Co-chair), Clarissa Anderson (SCCOOS, Co-chair), Greg Doucette (NOAA NCCOS), Marc Suddleson (NOAA NCCOS), Mike Brosnahan (WHOI), Tiffany Vance (NOAA IOOS), and Barb Kirkpatrick (GCOOS). 
  • Webinar March 16, 2022 - Thank you to everyone who joined our third webinar on March 16, 2022 from 3:00-4:15 PM EST focused on "Making Community Science Work". Our featured panelists, Dr. Steve Morton (NOAA NCCOS), Dr. George Bullerjahn (Bowling Green State University), Teri King (Washington Sea Grant), and Chris Whitehead (Sitka Tribe) discussed the importance of community science for HABs, shared examples of some successes and challenges of HAB community/citizen science, and addressed how an NHABON can assist with this process through data management and other efforts. If you missed the event, you can watch the recorded webinar here, and download a PDF version of the slides here.
  • Webinar December 1, 2021

Thank you to everyone who joined our second webinar on Wednesday, December 1, 2021 at 3:00 pm ET. The webinar was a panel focused on Emerging Data Science Tools for Managers and Scientists, which presented three strategies for a HAB data portal - the WHOI HABHub, the co-designing of a community HAB Data Assembly Center (HABDAC) and the HABScope. Panelists were: Rob Bochenek (Axiom Data Science), Dr. Mike Brosnahan (WHOI), and Bob Currier (GCOOS, Texas A&M).

  • Webinar September 1, 2021

Thank you to everyone who attended our first HAB Observing Group webinar on Wednesday, September 1, 2021 at 3:00 ET! During the webinar, Dr. Greg Doucette (NOAA NCCOS) provided an overview of the NHABON. If you missed the event, you can watch the recorded webinar here, download the presentation here, and read a news release about the event here.

  • News: How Bad is the Bloom? New Indexes Developed to Gauge the Severity of Red Tides. Dr. Barbara Kirkpatrick, Senior Advisor with the Gulf of Mexico Coastal Ocean Observing System (GCOOS) and member of the HAB Observing Group Steering Committee is the co-author of a new study recently published in the peer-review journal PLOS One that looked at red tides along Florida’s west coast between 1953 and 2019 and used cell counts of the organism that causes red tide in the Gulf of Mexico — Karenia brevis — to develop a Bloom Severity Index. The authors also looked at respiratory irritation reports between 2006 and 2019 and used that information to develop a Respiratory Irritation Index. These indexes now offer a standardized and objective way to gauge how severe red tides are, which should help decision makers better evaluate the risks of red tides as blooms occur and respond in ways that lessen bloom impacts on public health and local economies. Read more about this story on the GCOOS Website

HAB Observing Network

Welcome to the HAB Observing Network! The National HAB Observing Network (NHABON) is a key component to effectively and efficiently integrating local, state, regional, and federal HAB observing capabilities and delivering products operationally. The NHABON will: 

  • enable HAB detection, early warning, and forecasting;
  • leverage economies of scale and information and technology transfer between regions;
  • determine baselines and discern patterns/trends to assess the impacts of climate change, eutrophication, and other environmental forcings;
  • be tailored to the unique environmental and community needs of each region; and
  • provide observations to support state, tribal, and national missions of understanding, predicting, mitigating, and managing HABs. 

For more information, view the group's foundational documents: Framework for the National HAB Observing Network Workshop Report, and the Implementation Strategy for a National Harmful Algal Bloom Observing Network.

HAB Observing Group

Welcome to the HAB Observing Group! The HAB Observing Group (HAB OG) is designed to be an informal community-based coalition aimed at bolstering scientific collaboration and information/resource sharing for HAB observing system operators, data users and stakeholders, technology manufacturers, academia, and government agencies. 

You can join the HAB Observing Group email list, provide feedback, and give suggestions for future webinar topics by filling out this form.
