The term algal bloom is defined inconsistently depending on the scientific field and can range from a "minibloom" [when defined as?] of harmless algae to a large, harmful bloom event. [5] Since algae is a broad term including organisms of widely varying sizes, growth rates, and nutrient requirements, there is no officially recognized threshold ...
The resulting algal bloom sent a significant amount of carbon into the deep ocean, where it was expected to remain for centuries to millennia. The eddy was chosen because it offered a largely self-contained test system. [89] As of day 24, nutrients, including nitrogen, phosphorus and silicic acid that diatoms use to construct their shells ...
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.

Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...
The presence of blue-green algae blooms in the region’s lakes have prompted additional land acquisition strategies, according to Andy Zepp, executive director of the Finger Lakes Land Trust.
Scientists in attendance were interested in how harvesting algae could become a method to maintain and improve water quality. Algae to fertilizer: Harvester could help defend against Florida's ...
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, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem.
