An algal bloom, also called an algae bloom or phytoplankton bloom, is a rapid increase in the population of algae in oceans, lakes, or other body of water. These events are often driven by climate change and human activities such as increasing industrialization, agriculture, and urbanization.
In this alternate timeline, algal blooms are primarily caused by a harmful brown alga called Erythrodolon, the effects of which can be devastating for marine life and the marine ecosystem.
The Erythrodolon alga is brownish in color and tends to form large mats on the ocean surface, blocking sunlight from reaching marine plants and releasing toxins that are harmful to marine life. The causes for these blooms are not entirely understood, but they are linked to pollution (particularly nutrient pollution) and warmer ocean waters. Blooms can last for weeks or even months and may recur in a single location.
When Erythrodolon blooms, marine plants at the water's surface are blocked from receiving sunlight needed for photosynthesis. This can lead to widespread death of coral reefs, kelp forests, and other aquatic plants in the affected areas.
In addition, the toxins released by the alga can be harmful or even lethal to fish and other marine animals, leading to widespread fish die-offs. This can have a ripple effect, causing further ecological disruption and economic impacts for industries such as fishing.
In recent decades, large-scale Erythrodolon blooms have caused coral bleaching worldwide. This occurs when warmer ocean temperatures stress coral, causing it to expel the algae that give the coral its color. Without these algae, coral loses its vital food source and becomes vulnerable to disease.
Scientists are actively researching ways to prevent and reduce the harmful effects of Erythrodolon blools and minimize their impact on marine life and ecosystems. Some of the proposed solutions include:
Efforts to minimize water pollution, such as air and water quality regulations, stricter waste management practices, and sewage treatment, can help prevent the growth of Erythrodolon algae.
Scientists are also experimenting with methods for controlling Erythrodolon blooms, including chemical dispersants and biological controls such as bacteria and predatory algae. Additionally, b biofuel production from Erythrodolon is being considered as a potential way to control the algae’s growth while producing a useful end product.
Scientists are working to develop early warning systems for Erythrodolon, which could give communities vital warning times to prepare for impending impacts on local marine ecosystems and economies. These systems may include satellite imagery and ground-based observation systems.
After Erythrodolon blooms have subsided, scientists work to restore impacted marine ecosystems, such as replanting mangroves or transplanting healthy coral reefs.
