Coral reefs may be dissolving faster than expected under future climate change predictions, according to a new study from Southern Cross University marine scientists. The study indicates that the increasing levels of atmospheric carbon dioxide dissolving into seawater could reduce the rate of calcium carbonate sand formation – the structural foundations of coral reefs – […]
Biologists have reported on the impact of fishing on a group of fish known to protect the health of coral reefs. The report offers key data for setting management and conservation targets to protect and preserve fragile coral reefs.
In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. Show More Summary

While many scientists have been warning about potentially dire consequences of the ocean’s increasing acidity, a recent scientific paper suggested that coral reefs — such as those around Bermuda — might actually help offset ocean acidification. They point out the ocean is the largest natural sink for carbon dioxide (CO2), absorbing one quarter to one […]
Future coral reefs are expected to be subject to higher pCO2 and temperature due to anthropogenic greenhouse gas emissions. Such global stressors are often paired with local stressors thereby potentially modifying the response of organisms. Benthic macroalgae are strong competitors to corals and are assumed to do well under future conditions. The present study aimed […]
Ocean acidification threatens the foundation of tropical coral reefs. This study investigated three aspects of ocean acidification: (i) the rates at which perforate and imperforate coral-colony skeletons passively dissolve when pH is 7.8, which is predicted to occur globally by 2100, (ii) the rates of passive dissolution of corals with respect to coral-colony surface areas, […]
According to a paper published in the November issue of the journal Nature Climate Change, coral reefs may respond to ocean acidification in ways that will partially offset expected changes in seawater acidity taking place as the oceans take up human-produced carbon dioxide. Andreas Andersson, a chemical oceanographer at Scripps Institution of Oceanography at UC […]
We all know the feeling, it's a hot summer afternoon and you have no appetite and don't want to do anything apart from lay on the couch. A team of researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University...Show More Summary
One of the largest and longest experiments ever done to test the impact of nutrient loading on coral reefs today confirmed what scientists have long suspected -- that this type of pollution from sewage, agricultural practices or other sources can lead to coral disease and bleaching. But there was unexpectedly good news - when you cleaned up the water, the corals recovered.
The regulation of intracellular pH is a fundamental aspect of cell physiology that has received little attention in studies of the phylum Cnidaria, which includes ecologically important sea anemones and reef building corals. Like all organisms, cnidarians must maintain pH homeostasis to counterbalance reduction in intracellular pH, which can arise due to changes in either […]
Concerns have been raised about how coral reefs will be affected by ocean acidification1, 2, but projections of future seawater CO2 chemistry have focused solely on changes in the pH and aragonite saturation state (?a) of open-ocean surface seawater conditions surrounding coral reefs1, 2, 3, 4 rather than the reef systems themselves. The seawater CO2 […]
Coral reefs are famed for their vivid colors, which come not only from the corals themselves but the brilliant-hued species of fish that flit in and around the reef. Here, vermillion fish contrast with the deep blue of the water.

Coral reefs, jellyfish and seahorses are just some of the marine life that will be better protected following the creation of 27 new Marine Conservation Zones today. The UK has one of the world’s richest marine environments and these new sites will join over 500 marine protected areas that already exist to ensure it stays […]
Designed by the same firm that created The Utter Inn, an underwater resort docked in the middle of a Swedish lake, Manta Resort's floating addition is submerged thirteen feet beneath one of the Indian Ocean’s richest coral reefs. In addition to the underwater
Coral reefs, shellfish, and even top predators such as tuna could be devastated as human carbon-dioxide emissions continue to acidify the world’s oceans. These and other impacts of anthropogenic ocean acidification are laid out in a new expert assessment, released today. Oceans act as a huge carbon sink, sucking up much of the CO2 released […]
Global warming is causing a silent storm in the oceans by acidifying waters at a record rate, threatening marine life from coral reefs to fish stocks, an international study showed. The report, by 540 experts in 37 nations, said the seas could become 170 per cent more acidic by 2100 compared to levels before the […]

If you've always wanted to explore a coral reef at a tropical location, but can barely stand even getting your head wet in the shower, then scuba diving and snorkelling isn't for you. What could be the solution, though, is the Zayak Sea Sled, a curvaceous kick board with a window that lets the rider peer into the murky depths below. Read more...
