Belize's Lighthouse Reef Atoll is the home of the world-famous Great Blue Hole -- a massive underwater sinkhole and World Heritage Site. The islands that make up this ring of coral reefs are known for their crystal blue waters, white sand beaches, and vibrant coral reef. Show More Summary
Basin-scale calcification rates are highly important in assessments of the global oceanic carbon cycle. Traditionally, such estimates were based on rates of sedimentation measured with sediment traps or in deep sea cores. Here we estimated CaCO3 precipitation rates in the surface water of the Red Sea from total alkalinity depletion along their axial flow using […]
Ocean acidification due to rising atmospheric pCO2 slows down coral calcification and impedes reef formation, with deleterious consequences for the diversity of reef ecosystems. Such effects contrast with the capacity of corals to actively regulate the chemical composition of the calcifying fluid where calcification occurs. Show More Summary
This paper evaluates the global economic damage arising from the effects of climate change and associated carbon dioxide concentrations on the loss of coral reefs. We do this by first estimating the effects of sea surface temperature and carbon dioxide concentrations on coral cover. We develop a statistical relationship between coral coverage and sea surface […]
New science and software make Belize coastal zone management plan better for people and the environment. With historic expansion of coastal and ocean development, ecosystems like coral reefs and mangrove forests are put at unprecedented risk. Show More Summary
Coral reefs exist in a delicate balance between calcium carbonate (CaCO3) production and CaCO3 loss. Ocean acidification (OA), the CO2-driven decline in seawater pH and CaCO3 saturation state (?), threatens to tip this balance by decreasing calcification and increasing erosion and dissolution.

The Papah?naumoku?kea Marine National Monument in Hawaii, a World Heritage Site and one of the largest marine conservation areas in the world, is an isolated assortment of tiny uninhabited islands and coral reefs that are home to anShow More Summary
Jeremy Lin was the reason I got back into Knicks basketball. What a thrill. And what a story. On the verge of being cut. Last chance. And he gets in the groove. And the Knicks start winning! Their winning ways continue, even after he left. Show More Summary
Researchers at the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University in Australia have found a way to predict illegal fishing activities to help authorities better protect marine reserves. Marine reserves...Show More Summary
Harnessing 'people power' to manage fisheries in the developing world has significantly benefited local communities and coral reefs, according to new research.
The design and evaluation of replicated artificial mesocosms are presented in the context of a thirteen month experiment on the effects of ocean acidification on tropical coral reefs. They are defined here as (semi)-closed (i.e. with or without water change from the reef) mesocosms in the laboratory with a more realistic physico-chemical environment than microcosms. […]
And it wasn't happy. The Queensland Groper is one of the largest bony fishes, and is the largest on coral reefs. The species has been implicated in fatal attacks on humans, but none are fully documented. LINK
It's no secret that the world's corals are in trouble but right now in the waters around Hawaii, it's some of the rarest corals on Earth that are getting hammered. In recent weeks warming ocean temperatures near Oahu and Kauai have set off widespread bleaching. Show More Summary
Coral reefs, the “rainforests of the sea,” are some of the most biodiverse and productive ecosystems on earth. They occupy only.2% of the ocean, yet are home to a quarter of all marine species: crustaceans, reptiles, seaweeds, bacteria, fungi, and over 4000 species of fish make their home in coral reefs. With an annual [...]
The Gate Project boasts several renewable energy technologies meant to assure a 50 percent energy saving and a significant reduction in carbon footprint. A mesh surface unfolds above all the building volumes as a braided dress. This second skin in white steel
Changes in CaCO3 dissolution due to ocean acidification are potentially more important than changes in calcification to the future accretion and survival of coral reef ecosystems. As most CaCO3 in coral reefs is stored in old permeable sediments, increasing sediment dissolution due to ocean acidification will result in reef loss even if calcification remains unchanged. […]
Seaview divers routinely cover 2 kilometers in a dive and generate 3,000 panoramic images in a day. Only a fraction of the best are uploaded to Google Street View. The post Take a Google Seaview Tour of the World’s Most Stunning Coral Reefs appeared first on WIRED.
Global climate change and local anthropogenic pressures are among the primary factors leading to the decline of functional biodiversity and critical habitats in coral reefs. Coral bleaching, the potential decreases in dissolved oxygen...Show More Summary
By the end of the century coral reefs likely will be affected negatively by ocean acidification (OA), but both the effects of OA on coral communities and the crossed effects of OA with other physical environmental variables are lacking. One of the least considered physical parameters is water flow, which is surprising considering its strong […]
A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño.
