1. barrier reef

   A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian.Sometimes called rainforests of the sea, shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Coral reefs flourish in ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas. Coral reefs have declined by 50% since 1950, partly because they are sensitive to water conditions. They are under threat from excess nutrients (nitrogen and phosphorus), rising ocean heat content and acidification, overfishing (e.g., from blast fishing, cyanide fishing, spearfishing on scuba), sunscreen use, and harmful land-use practices, including runoff and seeps (e.g., from injection wells and cesspools).Coral reefs deliver ecosystem services for tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at anywhere from US$30–375 billion (1997 and 2003 estimates) to US$2.7 trillion (a 2020 estimate) to US$9.9 trillion (a 2014 estimate).

1. barrier reef

   A barrier reef is a type of coral reef that is separated from the shoreline by a lagoon or other body of water. It is characterized by its ridged, linear shape and forms a barrier that protects the shore from the open sea, mitigating the impact of waves and storms. It is a diverse marine ecosystem with abundant sea life. The most famous example of this is the Great Barrier Reef in Australia.

1. Barrier Reef

   Barrier Reef was an Australian television series that was first screened in 1971. Barrier Reef centred around a group of marine biologists on board a ship called the New Endeavour, researching around the Great Barrier Reef, off Queensland, Australia. "It was the first series in the world to feature extensive colour underwater filming on location". It was also a unique location for a TV show. The Great Barrier Reef is "The only living organic collective visible from Earth's orbit."

Examples of barrier reef in a Sentence

1. Scott Bryan:

   The pumice gets waterlogged or negatively buoyant and sinks to the sea floor and gets logged and stuck there, then those plants and animals and Great Barrier Reef can then continue to grow and grow in this new location.

2. Prince Charles:

   The fact that significant portions of the Great Barrier Reef on Australia’s eastern coast have been severely degraded or lost over the last few years is both a tragedy and also, I would have thought, a very serious wakeup call.

3. Ryan Pedley:

   It's another way to immerse our students in reef ecology, the kids don't actually have to visit Great Barrier Reef. They can do their part by breeding clownfish in captivity and donate them to the fish shops.

4. Climate Council:

   The Australian government has stewardship of one of the world's most precious and iconic ecosystems, but The Great Barrier Reef continued support for fossil fuels and its lack of effective climate policy means it's utterly failing to live up to that responsibility.

5. Terry Hughes:

   This has been the saddest research trip of my life, almost without exception, every reef we flew across showed consistently high levels of bleaching, from the reef slope right up onto the top of the reef. We flew for 4000 kilometers (2,485 miles) in the most pristine parts of the Great Barrier Reef and saw only four reefs that had no bleaching. The severity is much greater than in earlier bleaching events in 2002 or 1998.
