Harmful Algal Blooms

Harmful Algal Blooms

Harmful algal blooms (or HABs) present one of the most scientifically complex and economically significant coastal management issues facing the nation today. In the past, only a few regions of the U.S. were affected by these harmful algal blooms, but now all U.S. coastal regions have reported major blooms. These phenomena have devastating environmental, economic, and human health impacts. The Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) recognizes the significance of HABs and calls for research to advance scientific understanding and our ability to detect, assess, predict, control, and mitigate events. CSCOR HAB programs are advancing the state of the science by supporting interdisciplinary research studies to address HAB issues in an ecosystem context ... More

HAB Ecological Forecasting

Ecological forecasts are one type of integrative HAB research product that can help managers mitigate bloom events and reduce bloom impacts on coastal resources and economies. More

  • NOAA's HAB Forecasting System in the Gulf of Mexico is one example of a collaborative effort that integrates data from different sources to supply information on the location, extent, and potential for development or movement of harmful algal blooms in the Gulf of Mexico.
  • Operational demonstrations of biological/physical models for Alexandrium in the Gulf of Maine (New England Red Tide) have helped managers identify areas where sampling was most critical, allowing protection of human health while minimizing impacts on fisherman.

Human Dimensions

Some HABs present a significant threat to public health due to the toxins they produce. Closure of beaches and fisheries to protect public health can cause disruption of subsistence activities, loss of community identity tied to coastal resource use, disruption of cultural harvesting practices, social disruption for affected families and communities, and substantial lost revenue for economies dependent on seafood harvest or tourism. Reducing these impacts requires research to improve risk communication, to assess sociocultural and economic impacts, and to develop effective management strategies. More

Accomplishments

CSCOR is leading NOAA's effort to support research to understand how, when, and why blooms occur in an effort to develop better methods of detecting and predicting blooms, and to find ways to reduce or prevent impacts on humans, coastal economies, and ecosystems. More
