Model of the artificial coral reef. Why do they plant corals? Home to 25 percent of all marine life, corals are essential to the biological balance of the ocean. The geological formation of coral reefs protects our land from wind and wave erosion. Also, it has the func...
Some global efforts, such as the 50 Reefs Initiative, have used Modern Portfolio Theory (MPT) to identify coral reef locations that represent imperative conservation investments and to ensure their survival; the goal of these efforts is to prepare these areas for repopulation once the climate has ...
A variety of algae is always present in coral reef ecosystems; in fact, a few types are essential to the survival of corals and the formation of coral reefs. These diverse life forms were once classified as “plants”, but thanks to the huge advances in our understanding of evolutionary rel...
The latter is mainly the parameter inversion of atmosphere or water environment in which coral reefs exist, to evaluate or predict the health condition of coral reefs. In the past 30 years, the technology has developed from simple range monitoring to today’s complex reef benthic substrate ...
