Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]
Some harmful algal blooms resulting from eutrophication, are toxic to plants and animals. [21] [38] Freshwater algal blooms can pose a threat to livestock. When the algae die or are eaten, neuro- and hepatotoxins are released which can kill animals and may pose a threat to humans.
Discolored or smelly water could mean there is a harmful algal bloom in the water. If you see any pipes draining into or around the water, you should avoid swimming due to the heightened risk ...
An algal bloom, sometimes referred to as a “red tide,” is a cluster of algae that forms when the water around it is warm, slow-moving and full of nutrients, according to the Centers for ...
Blue-green algae, also known as cyanobacteria, typically grows in lakes, rivers, ponds, estuaries and marine water, according to the Washington State Department of Health, but not all blooms are ...
Excessive algal growth can also smother sensitive coral reefs and lead to loss of biodiversity and coral health. A second major concern is that the degradation of algal blooms can lead to consumption of oxygen in coastal waters, a situation that may worsen with climate change as warming reduces vertical mixing of the water column. [28]
The various sorts of algae play significant roles in aquatic ecology. Microscopic forms that live suspended in the water column (phytoplankton) provide the food base for most marine food chains. In very high densities (algal blooms), these algae may discolor the water and outcompete, poison, or asphyxiate other life forms.
