Plastics linked to disease in coral
An international team led by a JCU scientist has found that contact with plastic waste massively increases the chance of disease in corals. Dr. Lamb performing reef surveys on the Great Barrier Reef,…

New Eocene fossil data suggest climate models may underestimate future polar warming
A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth's potential future climate, was great…
Seabed mining could destroy ecosystems
Mining on the ocean floor could do irreversible damage to deep-sea ecosystems, says a new study of seabed mining proposals around the world. The deep sea (depths below 200m) covers about half of the …
New application for acoustics helps estimate marine life populations
Researchers at Scripps Institution of Oceanography at the University of California San Diego were part of an international team that for the first time used hydroacoustics as a method for comparing t…
Ancient outcrops give new depth limit for deep-sea burrows
Scientists have found fossil evidence of deep-sea marine life burrowing up to eight metres below the seabed -- four times the previously observed depth for modern deep-sea life. Cross-cutting burrows…
Mass extinctions remove species but not ecological variety
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and died. UChicago scientists examined how species (in…
Climate change drives collapse in marine food webs
A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate cha…
The ocean is losing its breath
In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased mor…
The window for saving the world's coral reefs is rapidly closing
The world's reefs are under siege from global warming, according to a novel study published in the journal Science . A researcher from the ARC Centre of Excellence for Coral Reef Studies surveys …
New study identifies thermometer for the past global ocean
There's a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published i…
Scientists find surprising evidence of rapid changes in the Arctic
Scientists have found surprising evidence of rapid climate change in the Arctic: In the middle of the Arctic Ocean near the North Pole, they discovered that the levels of radium-228 have almost doubl…
The Caribbean is stressed out
Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coast…
Sea-level rise projections made hazy by Antarctic instability
It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University-New Brunswick-led analysis. The study is the first to link globa…
Tiny ice losses at Antarctica's fringes can accelerate ice loss far away
A thinning of small areas of floating ice at Antarctica's coast can accelerate the movement of ice grounded on rocks hundreds of kilometers away, a new study shows. It is known that the ice shelv…
Unique field survey yields first big-picture view of deep-sea food webs
Deep-sea animals have been systematically studied for over 100 years, yet scientists are still learning about what many of these animals eat. A new paper by MBARI researchers Anela Choy, Steve Haddoc…
