Researchers Work To Understand Harmful Algal Blooms In. Researchers at the College of Science and Engineering's St. Anthony Falls Laboratory (SAFL) recently placed a customized data collection buoy in a Minnesota lake to examine lake dymanics and weather patterns that may trigger harmful blue-green algae blooms.

Harmful Algal Blooms (Red Tide). Harmful Algal Blooms. Harmful algal blooms, or HABs, occur when colonies of algae—simple photosynthetic organisms that live in the sea and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal.
Harmful Algal Bloom. A harmful algal bloom contains organisms that can severely lower oxygen levels in natural waters, killing marine life. Some HABs are associated with algae-produced toxins. Blooms can last from a few days to many months. After the bloom dies, the microbes which decompose the dead algae use up even more of the oxygen, which can create fish die-offs. When these zones of depleted oxygen cover a large area for an extended period of time, they are referred to as dead zones, where neither fish nor plan
Harmful Algal Blooms. Learn about harmful algal blooms. Harmful algal blooms can be green, blue, red or brown. They can be scummy or look like paint on the surface of the water. Harmful algal blooms are overgrowths of algae in water. Some produce dangerous toxins in fresh or marine water but even nontoxic blooms hurt the environment and local economies.
Algal Bloom Effects. Effects of Algal Bloom. Presence of algal blooms in marine waters are known to be one of the chief causes of shellfish poisonings. Dinoflagellates often take upon a reddish-brown hue due to which the infested waters assume a reddish tint. This is the reason behind the occurrence of red tides in coastal waters.
