NASA helps warn of harmful algal blooms in lakes, reservoirs

Harmful algal blooms can cause big problems in coastal areas and lakes across the United States. When toxin-containing aquatic organisms multiply and form a bloom, it can sicken people and pets, contaminate drinking water, ...

Remote sensing of toxic algal blooms

Harmful algal blooms in the Red Sea could be detected from satellite images using a method developed at KAUST. This remote sensing technique may eventually lead to a real-time monitoring system to help maintain the vital ...

Rice husks can remove microcystin toxins from water

Scientists at the University of Toledo have discovered that rice husks can effectively remove microcystin from water, a finding that could have far-reaching implications for communities along the Great Lakes and across the ...

Harmful algal bloom

A harmful algal bloom (HAB) is an algal bloom — a dense aggregation of phytoplankton, algae or cyanobacteria in a marine or aquatic environment — that causes negative impacts to other organisms via production of natural toxins, mechanical damage to other organisms, or by other means. HABs are often associated with large-scale marine mortality events and have been associated with various types of shellfish poisonings.
