Summary – Blue Hole
A blue hole is a large underwater sinkhole or cavern formed in carbonate bedrock like limestone or coral reefs. These fascinating formations can be hundreds of meters long and are found in areas with tidal influences. Blue holes are known for their deep blue waters, and some well-known examples include the Great Blue Hole, Dean’s Blue Hole, and the Dragon Hole. They are rich habitats for marine life, hosting various species such as sharks, sea turtles, and corals. Blue holes are formed over millions of years as the surrounding rock erodes, creating unique geological features. These underwater formations also play a crucial role in preserving fossils and records of climate due to sedimentation. The Great Blue Hole in Belize is a famous example, recognized as a UNESCO World Heritage Site within the Belize Barrier Reef Reserve System.
Blue Hole
Blue Hole: A blue hole is an underwater, large marine sinkhole or cavern. They can cover areas bigger than cities and are hundreds of meters long. Carbonate bedrock, such as coral reefs or limestone, makes up blue holes. They may contain tidally-influenced fresh, marine, or mixed water. By releasing nutrients, some of the holes help the biodiversity in their natural surroundings. Off the coast of Mexico, a blue hole measuring 900 feet deep was found in 2021. In February 2023, a study on the blue hole was first published in the Frontiers in Marine Science publication.
In this article, we will read about Blue Hole, interesting facts about them, the formation of blue hole, their location, biodiversity, and the great blue hole of Belize.
