We probably don’t have to mention the life-threatening conditions natural reefs are under today due to human behavior. However, artificial reefs, which are quite a new phenomenon, have proved to be a very good alternative as they are durable, environmentally
It's tough being the (nominal) leader of the free world, with people lookin' to you for leadership 'n' stuff. Vladimir Putin has put President Barack Obama?s vacation plans on hold. Obama is headed to Coral Reef High School in the.....
In many marine biogeographic realms, bioeroding sponges dominate the internal bioerosion of calcareous substrates such as mollusc beds and coral reef framework. They biochemically dissolve part of the carbonate and liberate so-called sponge chips, a process that is expected to be facilitated and accelerated in a more acidic environment inherent to the present global change.

Outbreaks of crown-of-thorns starfish (COTS), Acanthaster planci, contribute to major declines of coral reef ecosystems throughout the Indo-Pacific. As the oceans warm and decrease in pH due to increased anthropogenic CO2 production, coral reefs are also susceptible to bleaching, disease and reduced calcification. Show More Summary
Literal biodiversity reservoirs, coral reefs and associated ecosystems are in grave danger from natural and human-made disturbances. The latest World Resources Institute assessment is alarming with 75% of coral reefs reported as endangered worldwide, a figure that may reach 100% by 2050. Show More Summary
The Google Maps team has announced the addition of new underwater Street View images in locations around Mexico with the help of the Catlin Seaview Survey, an organization documenting the world's declining coral reefs via high-resolution,...Show More Summary
A new publication from researchers at the University of Southampton and the National Oceanography Centre, Southampton highlights the importance of nutrients for coral reef survival. read more
Scientists from the Wildlife Conservation Society, the ARC Centre of Excellence for Coral Reef Studies, and other groups have found that the fishing villages of Madagascar—a country with little history of natural resource regulation—are...Show More Summary
The weakly electric black ghost knifefish of the Amazon basin has inspired scientists to develop agile fish robots that could lead to a vast improvement in underwater vehicles used to study fragile coral reefs or repair damaged deep sea oil rigs.
Ocean acidification (OA) has important implications for the persistence of coral reef ecosystems, due to potentially negative effects on biomineralization. Many coral reefs are dynamic with respect to carbonate chemistry, and experience fluctuations in pCO2 that exceed OA projections for the near future. Show More Summary
Rising atmospheric CO2 concentrations threaten coral reefs worldwide by causing ocean warming and acidification. When seawater temperatures are unusually high, corals lose a significant portion of their vital algal endosymbionts and/or photosynthetic pigments making them appear pale or white – a process referred to as coral bleaching. As corals get most of their carbon from […]
Charles Darwin was born on Febrary 12th, 1809, and lived until 1882. He was a geologist who significantly advanced our understanding of how coral reefs form. He contributed to the study of archaeology through his study of soil formation processes. Darwin made many contributions to the collections of natural materials including insects and birds to…
Davidoff will launch Cool Water Coral Reef, the brand's 2014 limited edition summer flankers for the Cool Water fragrance series, in March. As with the last two sets of summer flankers, the sales will benefit the National Geographic Society's "Pristine Seas" program to protect the oceans. Other upcoming Davidoff fragrances include Cool Water Night Dive...
Recent studies have shown that elevated CO2 can affect the behaviour of larval and juvenile fishes. In particular, behavioural lateralization, an expression of brain functional asymmetries, is affected by elevated CO2 in both coral reef and temperate fishes. Show More Summary
The electric coral reef station floats between areas that require coral reefs to dissipate storms near coastlines. Complex geometry used in the solar-powered station, designed by Margot Krasojevic, buffers oncoming waves, slowing them down in the process.
The idyllic coral sands and crystal seas that lap the Great Barrier Reef are probably most people’s definition of a tropical paradise: but all is not well in paradise. As global CO2 levels rise, the pH at the surface of the oceans is gradually falling. Göran Nilsson from the University of Oslo, Norway, explains that […]
Diseases threaten the structure and function of marine ecosystems and are contributing to the global decline of coral reefs. We currently lack an understanding of how climate change stressors, such as ocean acidification (OA) and warming,...Show More Summary
By sheer coincidence, Canadian researchers have discovered a reef of living cold-water corals in southern Greenland. The first-ever Greenlandic reef is located in southwest Greenland and was formed by cold-water corals with hard limestone skeletons. There are several species of coral in Greenland, but this is the first time that an actual reef has been found.
Rising carbon emission from the burning of fossil fuels is increasing the acidity of Earth's oceans. That's very bad for coral reefs, because in acidic environments they can't form calcium carbonate, the building block of corals.
