With algal blooms evidently harmful for the environment, aquatic and human health, there are significant efforts underway to better understand and predict how these events evolve. The goal will enable water companies and others to address the numerous economic impacts associated with HABs across human health, fisheries tourism and recreation, as well as the costs of monitoring and management.

Harmful algal blooms can be stimulated by environmental factors, such as light, warmer water temperatures and excessive nutrients.
