Harmful Algal Bloom Forecasting

Our HAB forecasts alert coastal managers to blooms before they cause serious damage. Short-term (once or twice weekly) forecasts identify which blooms are potentially harmful, where they are, how big they are, and where they're likely headed. Longer-term, seasonal forecasts predict the severity of HABs for the bloom season in a particular region. Early warning provides health officials, environmental managers and water treatment facility operators information to focus their testing to guide beach and shellfish bed closures or water treatment in a more appropriate timeframe. They also allow the seafood and tourism industries to minimize impacts.

HAB Forecasting by Region

HAB forecasts are based on understanding the causes of HABs and how they respond to changing weather and ocean conditions. The other critical component of a HAB forecast is the ability to routinely and remotely detect HABs, their toxins, and environmental conditions that foster blooms and enhance their toxicity.

Harmful Algal Bloom Monitoring System

NCCOS developed the Algal Bloom Monitoring System to routinely deliver near real-time products for use in locating, monitoring and quantifying algal blooms in coastal and lake regions of the US. This application delivers a suite of bloom detection products in the form of geographic based images. At this time products are available for selected regions. New products are being evaluated, and new regions are being considered; as they are proven useful, they will be made available through this system.
