Global warming fuels coral killer, study finds

Global warming worsens a disease that has almost wiped out Caribbean coral reefs, according to a new study by researchers at the Florida Institute of Technology. In only 40 years, the iconic elkhorn and staghorn corals that have dominated Caribbean reefs for 3.5 million years have declined by more than …

NOAA rejects whale, coral sanctuary request in Atlantic

A North Florida non-profit proposing a National Marine Sanctuary for Northern right whales and Oculina coral that would cover more than 7,000-square miles of ocean from Jacksonville to Fort Pierce is headed back to the drawing board after having its initial application rejected by the National Oceanic and Atmospheric Administration. …

Corals in Australia's Great Barrier Reef Eat Plastic

It turns out that corals are making use of the plastic in our oceans-sort of. Scientists have found that corals commonly found on the Great Barrier Reef are actually eating plastic. In this case, the corals are consuming microplastics, which are tiny fragments of plastic in the environment that are …

Climate change is really bad news if you like oysters, scallops and clams

When it comes to carbon dioxide emissions, the first environmental problem that comes to mind is climate change. As humans pump more of this greenhouse gas into the air, the Earth gets warmer, and the climate changes in ways that could damage the economy, public health, infrastructure and society. But …

Ocean Acidification Threatens US Coastal Communities Too

It's no secret that ocean acidification is wreaking havoc on the corals, sea stars, sharks and others that live beneath the waves. But now new research shows that this phenomenon is hitting closer to home and threatening US coastal communities, too. A lot of marine life may face extinction in …

Vulnerability and adaptation of US shellfisheries to ocean acidification

Ocean acidification is a global, long-term problem whose ultimate solution requires carbon dioxide reduction at a scope and scale that will take decades to accomplish successfully. Until that is achieved, feasible and locally relevant adaptation and mitigation measures are needed. To help to prioritize societal responses to ocean acidification, we …

Scientists Discover Extinction Risk for 20 to 25 Percent of Marine Species

It turns out that our world's seas are quickly becoming ecosystems where species are at risk for extinction. Scientists have discovered that 20 to 25 percent of species in our oceans are now threatened with extinction. In order to better understand the state of species in our world's oceans, the …

Barrier Reef coral genetically altered in hope of surviving climate change

The Australian government’s marine research agency is looking to genetically alter species of coral to help them cope with rising sea temperatures, as new modelling showed the coverage of living corals on the Great Barrier Reef could decline to less than 10% if warming continued. Scientists at the Australian Institute …

Sea turtles fall victim to 'alarming' flood of plastics entering Australian waters

Rates of marine animals needing treatment for ingesting plastic bags, balloons and other waste in Australian waters have “accelerated dramatically” in the past decade, according to veterinarians, the toll of more than five trillion pieces of plastic floating in the world’s oceans largely unseen. The manager of Sydney’s Taronga Zoo …

Great Barrier Reef could see coral cover go below tipping point due to warming

Live coral coverage on Australia's Great Barrier Reef could plummet to less than 10% if ocean warming continues according to current trends, finds a new study that explores the short- and long-term consequences of environmental changes to the reef. The long-term consequences indicate that a moderate warming of 1-2 degrees …

Mexico to employ drones in tracking endangered porpoise species

Mexico has begun testing unmanned drones that could help it save the critically endangered vaquita marina, the world’s smallest porpoise, which is threatened by illegal fishing in the upper Sea of Cortez. Alejandro del Mazo, an assistant prosecutor with Mexico’s environmental protection agency, said on Monday he hopes to have …

Final reckoning looms for BP in Deepwater Horizon case

Five years after the Gulf of Mexico disaster, oil company faces a fine of up to $13.7bn as Judge Carl Barbier begins assessment This Tuesday, close to five years after an explosion on the Deepwater Horizon oil rig claimed 11 lives and poured millions of barrels of oil into the …

Coral reefs bounce back from severe environmental impact

The team monitored 21 reefs in the Seychelles since 1994, taking measurements of total number of plant-eating fish and nutrients reaching the reefs. Twelve out of 21 reefs were able to recover after severe bleaching in 1998. The remaining became seaweed-covered ruins, writes Scientific American. Cutting down on the amount …

Ocean Life Faces Mass Extinction, Broad Study Says

A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them. “We may be sitting on a precipice of a major extinction event,” said Douglas J. …

New Species Discovered Two Miles Below the Surface of the Ocean

Two miles below the surface of the ocean, a strange species of microbes thrives. Now, scientists have learned a bit more about these new microbes that "breathe" sulfate. The microbes have yet to be classified and named, but they exist in massive undersea aquifers, which are networks of channels in …

Sizing up giants under the sea

Research team corrects inaccuracies and elucidates measurements for 25 marine species National Evolutionary Synthesis Center (NESCent) A team of scientists and undergraduate students have analyzed the body size for 25 marine species, including whales, sharks, squids, and other ocean giants. The project elucidates both the challenges of arriving at exact …

Calcifying species sensitivity distributions for ocean acidification

Increasing CO2 atmospheric levels lead to increasing ocean acidification, thereby enhancing calcium carbonate dissolution of calcifying species. We gathered peer-reviewed experimental data on the effects of acidified seawater on calcifying species growth, reproduction, and survival. The data were used to derive species-specific median effective concentrations, i.e., pH50, and pH10, via …

Marine invertebrates as bioindicators of heavy metal pollution

Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are terrestrial products, they flow into the sea through effluents and sewage or are directly discharged from industries placed …

Peru investigates deaths of 500 sea lions on north coast

Peru is investigating the deaths of some 500 sea lions found on a beach on its northern coastline. The local governor has accused fishermen of poisoning the mammals, which usually come close to the shore looking for food. But Peruvian environmental police are looking into other possible causes for the …

World Parks Congress: call to extend no-take share of marine protected areas

The world's oceans need expanded regions where fishing is barred to help preserve fragile ecosystems and protect them from what one leading biologist dubbed "a silent storm" driven by climate change. The World Parks Congress, a once-in-a-decade event, wrapped up in Sydney on Wednesday with calls to ensure at least …
