The microorganisms that help keep coral reef ecosystems healthy and thriving have different levels of activity at night and during the day, according to a new study. Corals are just one part of a reef ecosystem, and each piece plays a key role in the health and adaptability of coral reefs.
In 1998, a mass bleaching event hit reefs in the Seychelles, leading to a devastating loss of 90% of the African island nation’s live coral. While that event wasn’t caused by climate change (rather by El Niño, a recurring climate pattern that causes ocean warming every few years), global heating ...

Coral reefs in the western Indian Ocean are at risk of extinction by 2070 due to warming temperatures and overfishing, according to a new study.
Humans don’t know what they’re missing under the surface of a busy shipping channel in the “cruise capital of the world.” Just below the keels of massive ships, an underwater camera provides a live feed from another world, showing marine life that’s trying its best to resist global warming.
Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research.
In an effort to keep the world's coral reefs from disappearing forever, a number of reef restoration projects are currently underway … but how can scientists tell if any one of those projects is working? The answer may lie in listening to the reefs.
Coral reefs might only cover a tiny fraction of the ocean floor, but they are home to around a quarter of all marine species. Many though are dying due to warming oceans and pollution. In this episode, Ocean looks at what's been done to not only preserve reefs but also bring them back to life.
June 27 (UPI) -- At least one coral species has a taste for microplastic pollution. According to a new study, the coral species Astrangia poculata prefers the tiny plastic bits to its normal diet.
The effective extinction of many coral species may be weakening reef systems and siphoning life out of the corals that remain, US researchers warn.
President Carlos Alvarado of Costa Rica has signed a decree expanding the Cocos Island National Park, increasing the fully protected area in their Pacific waters by almost 53,000 square kilometers.
Three times the size of the country’s mainland, the reserve’s abundance of sharks, whales, turtles, and other marine life has been described as an “underwater Jurassic Park.”
Corals in the Gulf of Aqaba have a unique evolutionary history that could help them survive the climate crisis. Scientists even hope to breed their resilience into other reefs.
COLOMBO, Sri Lanka — A crackdown on unregulated explosives in the aftermath of deadly terrorist attacks in Sri Lanka may help in the fight against illegal blast fishing in the country’s waters, according to marine researchers.
A few times a day, off the Faroe Islands’ coast, the crew of the Jákup Sverri marine survey ship test the water, measuring its salinity, temperature and oxygen at different sea depths. But they also look for something else.
It is likely that coral reefs around Cyprus will die in the near future because of climate change and unsustainable tourism, but there is more to the story, marine ecologist Louis Hadjioannou told the Cyprus Mail.
Much more oxygen than previously thought is transported deep into the ocean interior through a 'trap door" in the Labrador Sea that some researchers say could be closing as a result of climate change.
Analysis of a strange skull in storage for the last 30 years has shown it belonged to the offspring of a narwhal mother and a beluga whale father.
Sir David Attenborough is supporting a campaign to help save an important marine habitat.Kelp forests of the West Sussex coast are one of the most biodiverse environments on the planet, but they have been damaged by changing fishing habits and sediment being dumped on the seafloor.
A virulent and fast-moving coral disease that has swept through the Caribbean could be linked to waste or ballast water from ships, according to research.
It’s the whole ecosystem – just gone in that area,” said James Cole. The eighth or ninth generation of Whitby fishers in his family, Cole has never seen anything like the death and decimation of marine life that has plagued the waters since autumn, from coral, crabs, seals and sea birds.
Ocean-warming over the past century may be impacting one of the largest but least understood components in the global carbon cycle: massive deep-sea deposits of "marine snow". The term is used to describe organic matter and detritus falling to the ocean floor. The material functions as Earth’s l ...
Hydrologists diving off the coast of the Philippines have discovered volcanic seeps with some of the highest natural levels of C02 ever recorded. The scientists were working in Verde Island Passage, one of the most diverse marine ecosystems in the world and is home to thriving coral reefs.
Scientists have discovered stunning "gardens" of deep-sea corals in the mysterious Bremer Canyon Marine Park off southwestern Australia during an oceanographic expedition.
A new study is shedding light on what lies in the deep. This first-ever deep-sea survey of both ends of the Salas y Gómez and Nazca ridges has revealed unique and fragile species. It also spurred a call for the protection of deep-sea habitats.
New research sees two-thirds of mollusc types only found living by hydrothermal vents added to IUCN’s red list of endangered species
Greenpeace report reveals 29 floor-exploration licences have been granted worldwide
Private mining firms and arms companies are exerting a hidden and unhealthy influence on the fate of the deep-sea bed, according to a new report highlighting the threats facing the world’s biggest intact ecosystem.
Although Planet Earth has a total surface area of about 510.1 million km2, approximately 70.9% is covered by drainage features like oceans, seas, rivers, lakes, streams, gulfs, and other water reservoirs. Oceans and their marginal seas are the world’s largest and deepest waterbodies.
The size and impact of Pacific Ocean tsunami waves on the Australian coastline are significantly reduced by healthy coral structures in the Great Barrier Reef, research shows.

The United States’ coral reefs are in fair condition, according to a recent reef condition status report, but vulnerable to decline. Scientists estimate that along the coast of Florida, where degradation is most severe, perhaps as little as 2% of original coral cover remains.
