Coral Bleaching
-
Not all corals respond to bleaching events by turning ghostly white, with some instead becoming shimmering arrays of bright neon colors. The authors of a new study believe this is an attempt to lure the much-needed algae back home.
-
Among the potential solutions to coral bleaching and death is the idea of developing new types of coral that are more resistant to heat, and researchers in Australia are reporting new success in this area using a technique called directed evolution.
-
Australia’s Great Barrier Reef is a prime example of the negative impacts of global warming, having already suffered back-to-back severe mass bleaching events in the past five years. Scientists have this week confirmed it is in the midst of a third

New research suggests the world's coral reefs face a battle to survive in the face of warming and more acidic waters, with scientists behind the new study projecting that as much as 90 percent of them could disappear within a couple of decades.
-
Three species of Caribbean coral are hardy enough to survive the rising levels of ocean acidification expected to take place over the next century. Whilst the corals were able to live in the unusually hostile environment, their skeletons were seriously affected, leaving them vulnerable to erosion.

That Australia’s Great Barrier Reef is in serious trouble is no longer subject to debate, but the best way to deal with the problem very much is. The latest idea to emerge involves robots playing the role of "the stork" and distributing coral larvae across the Reef to promote new growth
-
As the fate of the Great Barrier Reef remains uncertain, a new study has examined the health of the reef over the last 30,000 years, and found that it has suffered five “death events” in the past – but its current woes could be the last straw.
-
We've recently seen a number of proposals for protecting coral reefs from the dangers of climate change, and now it turns out that corals already have a self-defense mechanism. They can release aerosols into the atmosphere to create a protective "cloud umbrella."
-
Although the outlook may be bleak for the world's coral reefs overall, there might at least be hope for little bits of them. Scientists at the Great Barrier Reef Foundation have announced development of an eco-friendly film that could help protect corals against bleaching.
-
Typically, when conservationists are trying to restore dying coral reefs, they do so by manually fastening fragments of live coral to the existing reef. Thanks to new technology developed by SECORE International, however, reef restoration may soon be as easy as sowing seeds in a garden.
-
The Great Barrier Reef has seen better days, after a one-two punch of coral bleaching events struck it in 2016 and 2017. Warming sea temperatures has been pegged as the culprit, but researchers have found that a “perfect thermal storm” of oceanographic conditions led to the 2016 mass bleaching.

Reef-forming coralline algae is currently at risk due to climate change, and scientists are doing something about it. They're creating synthetic reefs in the Mediterranean Sea, made from artificial coralline algae.
