Maps, Tools & Applications

Harmful algal blooms (HABs), sometimes known as “red tide”, occur when certain kinds of algae grow very quickly, forming patches, or “blooms”, in the water. These blooms can emit powerful toxins which endanger human and animal health. NCCOS conducts and funds research that helps communities protect the public and combat blooms in cost-effective ways, and we are breaking new ground in the science of stopping blooms before they occur.

The Pharmaceuticals in the Environment website is designed to provide available information for assessing risks to aquatic resources from drugs entering waterways from both point and non-point sources. The website includes information on frequently prescribed drugs as well as most antibiotics and lipid-lowering drugs.

NCCOS runs the Phytoplankton Monitoring Network (PMN) to link volunteers who monitor for marine phytoplankton and HABs in cooperation with professional scientists. We build a more informed public while expanding the reach and resolution of HAB monitoring. Over 200 PMN volunteers sample 140+ sites in 17 states and the US Virgin Islands.

The Vibrio Predictive Models combine state of the art hydrodynamic models with specific algorithms for Vibrio, to provide early warning of these potential coastal hazards. Knowing where and when to expect elevated concentrations of Vibrio, and environmental conditions that promote rapid growth can inform both management and individual grower harvest decision making in the shellfish industry.
