Algal bloom
Definition
An algal bloom is a rapid increase in the population of algae in an aquatic system, often due to excess nutrients. These blooms can have harmful effects on water quality, marine life, and human health.
5 Must Know Facts For Your Next Test
- Algal blooms are primarily caused by nutrient pollution from agricultural runoff and wastewater.
- Harmful algal blooms can produce toxins that affect both marine organisms and humans.
- Algal blooms can lead to hypoxic or 'dead zones' where oxygen levels are too low to support most marine life.
- Some algal blooms are bioluminescent, creating glowing water at night.
- Monitoring and managing nutrient levels is key to preventing harmful algal blooms.

Related terms
Eutrophication: The process by which a body of water becomes excessively enriched with nutrients, often leading to algal bloom.
Hypoxia: A condition in which there is insufficient oxygen in the water, often resulting from algal bloom decomposition.
Nutrient Pollution: Contamination of water bodies with excessive amounts of nutrients like nitrogen and phosphorus, promoting algal growth.
