Researchers develop novel microscope to study the underwater world

Tue, 07/12/2016 - 10:55

A new microscopic imaging system is revealing a never-before-seen view of the underwater world. Researchers have designed and built a diver-operated underwater microscope to study millimeter-scale processes as they naturally occur on the seafloor.

UK's oldest deep-water Marine Protected Area successfully protects coral reefs

Wed, 06/29/2016 - 09:00

Deep, cold-water corals are very slow to recover from damage, a new, unique study shows. Therefore, say researchers, deep-water Marine Protected Areas (MPAs) protect vulnerable marine ecosystems most effectively when they are put in place before that damage occurs.

'Coral zombies' may spell doom for coral reefs around world

Tue, 06/21/2016 - 18:31

Scientists have known for a while that coral reefs around the world are dying, and in a worst-case scenario they were counting on large, healthy-looking corals to repopulate. But a new study shows that these seemingly healthy colonies are 'Coral Zombies' with no reproductive ability, which makes them useless in a recovery effort.

Coral reefs facing a hot time and increased bleaching, especially along US coasts

Mon, 06/20/2016 - 18:13

A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented third year in a row, leading to increased bleaching - and with no signs of stopping. While the bleaching event is global, it will hit the US hard.

Heat sickens corals in global bleaching event

Mon, 06/20/2016 - 10:20

Australian scientists report that many surviving corals affected by mass bleaching from high sea temperatures on the northern Great Barrier Reef are the sickest they have ever seen.

Bright spots shine light on the future of coral reefs

Wed, 06/15/2016 - 12:47

In one of the largest global studies of its kind, researchers conducted over 6,000 reef surveys in 46 countries across the globe, and discovered 15 'bright spots' -- places where, against all the odds, there were a lot more fish on coral reefs than expected.

Algorithm ranks thermotolerance of algae

Mon, 06/13/2016 - 14:38

A new tool could play an important role in the race to save coral reefs and in any application that relies on rankings. The novel algorithm could help assess and predict the future of coral bleaching events by better understanding the coral's symbiotic partner: algae.

Fishing prohibitions produce more sharks along with problems for fishing communities

Wed, 06/08/2016 - 16:43

Scientists have good news about fishing closures established in Indonesia's shark sanctuary, which are good for sharks and other fish. The bad news: People who rely on shark fishing for their livelihoods have few other options but to fish in unprotected areas and sometimes turning to illegal practices.

Coral killers

Tue, 06/07/2016 - 21:01

In a three-year effort to understand the effects of known stressors such as overfishing and nutrient pollution on coral reefs, scientists made a totally unexpected finding: A normally healthy interaction between fish and coral had turned deadly. The new work also shows how rising ocean temperatures are potentially lethal for coral reefs.

Coral reefs fall victim to overfishing, pollution aggravated by ocean warming

Tue, 06/07/2016 - 11:06

Coral reefs are declining around the world because a combination of factors -- overfishing, nutrient pollution, and pathogenic disease -- ultimately become deadly in the face of higher ocean temperatures, researchers have concluded. The findings are based on one of the largest and longest studies done on this issue.

Saving Nemo: Bleaching threatens clownfish

Wed, 05/25/2016 - 13:05

Clownfish became a household name over a decade ago when Disney released the movie 'Finding Nemo.' The colorful fish are now at risk due to bleaching of their sea anemone homes in the Indo-Pacific, which has increased due to rising ocean temperatures. Researchers demonstrate how vulnerable clownfish are to the increased frequency of bleaching events.

Coral bleaching 'lifeboat' could be just beneath the surface

Tue, 05/24/2016 - 11:40

A report commissioned by the United Nations offers a glimmer of hope to those managing the impact of bleaching on the world's coral reefs, including the Great Barrier Reef. The 35 authors of the United Nations Environmental Programme in-depth report say as the world's surface reefs are being threatened, part of the ecosystem may survive in these barely known deeper environments, known as mesophotic coral ecosystems (MCEs).

Networking lets sharks off the hook

Mon, 05/23/2016 - 15:04

Tuna fishers who network with their competition may be able to stop thousands of sharks a year from being accidentally captured and killed in the Pacific Ocean, according to new research.

Rich coral communities discovered in Palamós Submarine Canyon in the Northwestern Mediterranian Sea

Fri, 05/20/2016 - 09:19

A scientific team has found in La Fonera canyon, also known as the Palamós canyon in the Northwestern Mediterranian Sea, deep-water coral communities, a marine ecosystem which is very vulnerable to human activity.

Biodiversity protects fish from climate change

Mon, 05/16/2016 - 17:12

Fish provide protein to billions of people and are an especially critical food source in the developing world. Today marine biologists confirmed a key factor that could help them thrive through the coming decades: biodiversity. Communities with more fish species are more productive and more resilient to rising temperatures and temperature swings, according to a new study.

Coal shipping threat to Great Barrier Reef

Mon, 05/16/2016 - 09:32

Australian researchers have raised fresh concerns that a major shipping disaster could harm the Great Barrier Reef, with new research revealing coal dust in seawater can kill corals and slow down the growth rate of seagrasses and fish.
