Welcome To HABCAST

HABCAST, Harmful Algal Bloom Collaboration to Advance Stakeholder Tools, is a community of practice (CoP) that works to engage, share issues of concern, synthesize information, build expertise, acquire and develop new tools and products, and more fully integrate HAB outreach within Sea Grant and partner networks.

HABCAST is a network of people to facilitate data acquisition, synthesis, and the transfer of technology and knowledge.

Harmful algal blooms (HABs) have been reported to occur in the surface waters of all 50 U.S. states and are increasing globally. HABs occur when photosynthetic algae that live in fresh, brackish or marine waters grow out of control (i.e., “bloom”) and have adverse effects on people or ecosystems.

These HABs can result in significant socioeconomic impacts due to shellfish closures, wild or farmed fish mortalities, human health impacts, lost coastal recreation and tourism, reduced waterfront property values, and consumers who avoid consuming seafood. As a result, HABs are not only compromising the health of our coastal ecosystems, but they are also affecting the resiliency of our communities and economies. Early detection can mitigate some of the harmful effects of HABs, thus reducing associated socioeconomic impacts.

Why A Community of Practice?

Communities of practice (CoP) are formed by people who engage in a process of collective learning in a shared domain. Benefits of a HABCAST CoP to project partners and the larger national network include:

  1. A mechanism for engagement on the development of decision-making tools is provided.
  2. Capacity around satellite data use via value-added training is increased.
  3. Ideas and lessons learned are shared.
  4. Integrated, user-friendly HAB forecast services are delivered to a broad range of coastal stakeholders.
  5. Research gaps are identified and filled, thus moving more states/regions towards more reliable and accurate forecasting models.
  6. HAB products and decision support tools across the Sea Grant network are enhanced.

About The NOAA HAB Liaison

HABCAST is led by NOAA HAB Liaison Betty Staugler. Housed within Florida Sea Grant, Staugler forges and enhances partnerships by providing expertise, research, and extension services that leverage partners’ work to efficiently meet the needs of coastal and Great Lakes communities threatened by harmful algal blooms (HAB). This includes seeking new ways to extend NOAA HAB products and services, while also informing NCCOS, CoastWatch, and IOOS on Sea Grant stakeholder needs and research priorities.

Working Together


By working together and through a national liaison, HABCAST establishes and maintains a network of people to facilitate data acquisition, synthesis, and the transfer of technology and knowledge.

HAB Tools By Location

The following tabs contain links to existing monitoring and forecasting tools available nationally and in coastal regions and states. Tools include:

  • Real-time daily and multi-day imagery
  • Forecasts and warnings of HAB extent, trajectory and toxicity
  • Scenario-based predictive models
  • Monitoring and observations systems that support forecasts
