A NASA flying laboratory is using a specially designed sensor in a search for answers about what is killing large sections of the world’s coral reefs.
These are the amazing scenes as scuba divers off the coast of Australia are 'eaten alive' by giant Napoleon Wrasse fish who patrol tropical coral reefs looking for their next dinner.
Incubation experiments were carried out to determine the effect of eutrophication on carbonate dissolution under high pCO2 (partial pressure of carbon dioxide) condition in coral reef ecosystem at Sesoko Island, Okinawa, Japan. Short...Show More Summary
Coral reefs have experienced a global decline due to overfishing, pollution, and warming oceans that are becoming increasingly acidic. To help halt and reverse this decline, interventions should be aimed at those threats reef experts and managers identify as most severe. Show More Summary
High levels of carbon dioxide could impair the brain chemistry of fish, scientists found. Researchers from the University of Miami Rosenstiel School of Marine and Atmospheric Science and the ARC Center of Excellence for Coral Reef Studies at James Cook University found that increased concentrations of carbon dioxide in the ocean alters the brain chemistry […]
Tropical coral reefs lose up to two thirds of their zooplankton through ocean acidification. This is the conclusion reached by a German-Australian research team that examined two reefs with so-called carbon dioxide seeps off the coast of Papua New Guinea. At these locations volcanic carbon dioxide escapes from the seabed, lowering the water’s acidity to […]
Crochet Coral Reef: TOXIC SEA S brings attention to the destruction of coral reefs by human impact and plastic garbage. Margaret and Christine Wertheim, along with other artists from their organization, The Institute for Figuring, have been working on this collective art piece for over 10 years. Show More Summary
Projected ocean acidification will have a detrimental impact on coral reef ecosystems, where fleshy algae are expected to replace corals. Of particular importance to reef ecosystems are fleshy turf algal communities, which have the potential to overgrow corals; few studies have investigated the community structure and diversity of turfs to climate change. Here, we assessed […]
A new study from the Woods Hole Oceanographic Institution (WHOI) will help researchers understand the ways that marine animal larvae use sound as a cue to settle on coral reefs. The study, published on August 23rd in the online journal...Show More Summary
Rising CO2 levels can inhibit coral reef growth and starve associated animals, a new study shows. CORAL REEFS AND their associated animals are more sensitive to global warming than previously thought, according to a new study that shows how ocean acidification wipes out zooplankton populations, which are vital for coral survival. Researchers at the Australian […]
The in situ effects of ocean acidification on zooplankton communities remain largely unexplored. Using natural volcanic CO2 seep sites around tropical coral communities, we show a threefold reduction in the biomass of demersal zooplankton in high-CO2 sites compared with sites with ambient CO2.

While climate change threatens coral reefs in oceans around the world, not all reefs are affected equally. As oceans warm, physical forces like wave strength and water flow influence which reefs thrive and which die, according to a study led by Justin Rogers, a postdoctoral researcher at Stanford's Environmental Fluid Mechanics Laboratory.
The technique offers an affordable, modular and low-carbon structure in which to rebuild marine habitats
Neurosensory and behavioural disruptions are some of the most consistently reported responses upon exposure to ocean acidification-relevant CO2 levels, especially in coral reef fishes. The underlying cause of these disruptions is thought to be altered current across the GABAA receptor in neuronal cells due to changes in ion gradients (HCO3? and/or Cl?) that occur in […]

Coral reefs are among the most biologically diverse and economically important ecosystems on the planet. However, anthropogenic CO2 emissions are driving unprecedented changes in the tropical oceans, where the vast majority of shallow water reefs exist. Show More Summary
Vast coral reefs surrounding this island are considered by many experts to be the healthiest and best-protected in the Caribbean, and that makes Bonaire an ideal spot to test whether 3D printing technology can help preserve these vital marine habitats around the world.
“A NASA airborne mission designed to transform our understanding of Earth's valuable and ecologically sensitive coral reefs has set up shop in Australia for a two-month investigation of the Great Barrier Reef, the world's largest reef ecosystem,” reports NASA's Jet Propulsion Laboratory today.

Along with a sizeable chunk of the world's cities and roadways, Google StreetView lets users explore coral reefs, the Grand Canyon, the Amazon river, and the tiny streets of the world's largest model railroad display, without having to put on pants. Show More Summary
