The Great Barrier Reef and other World Heritage Sites are under immediate threat of collapse if better management practices are not implemented soon, according to research published recently in Science. Read about why and what can be done on EurekAlert!.


Video: Research by Hebrew University of Jerusalem researchers has shed some light on exactly how octopuses manage their uniquely unusual biology. Check out some detailed videos of their work here and here, then read about it on EurekAlert!.

Scientists discover elusive secret of how continents formed
An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion years ago -- and how those processes have continued within the last 70 million years to profoundly affect the planet's life and climate.

Discovery of 2 new species of primitive fishes
Working with an international team, paleontologists at the University of Zurich have discovered two new species of Saurichthys. The ~242 million year old predatory fishes were found in the fossil Lagerstätte Monte San Giorgio, in Ticino. They are distinct from previously known Saurichthys species in the shape of the head and body, suggesting different habitats and diet.

UNH geologist identifies new source of methane for gas hydrates in Arctic
Researchers have identified a new source of methane for gas hydrates -- ice-like substances found in sediment that trap methane within the crystal structure of frozen water -- in the Arctic Ocean. The findings, published online now in the May 2015 journal Geology, point to a previously undiscovered, stable reservoir for methane that is 'locked' away from the atmosphere, where it could impact global climate change.

Massive study is first to explore historical ocean response to abrupt climate change
A new study reports that marine ecosystems can take thousands, rather than hundreds, of years to recover from climate-related upheavals. The study's authors -- including Peter Roopnarine, Ph.D., of the California Academy of Sciences -- analyzed thousands of invertebrate fossils to show that ecosystem recovery from climate change and seawater deoxygenation might take place on a millennial scale.

NASA's ISS-RapidScat sees Typhoon Maysak's stronger winds become more uniform
A tropical cyclone does not always have consistently strong winds all the way around it, and NASA's ISS-RapidScat instrument confirmed that was the case with Typhoon Maysak as it was strengthening in the Northwestern Pacific Ocean. Over the course of three days, As the tropical cyclone strengthened, RapidScat saw strongest sustained winds around Typhoon Maysak expand and spread from the northern quadrant to other quadrants of the storm.

Equatorial fish babies in hot water
Scientists have discovered that rising ocean temperatures slow the development of baby fish around the equator, raising concerns about the impact of global warming on fish and fisheries in the tropics.

New research identifies diverse sources of methane in shallow Arctic lakes
New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments, may ramp up production of the potent greenhouse gas -- which has a global warming potential 25 times greater than carbon dioxide.

Sea change: What took decades to destroy in oceans took millennia to recover
While climate change and the deoxygenation of seawater can alter ocean ecology very quickly, recovery can be on a 1,000-year scale, not the 100-year scale previously thought.

Glow in the dark tampons identify sewage pollution in rivers
Tampons may not be an obvious scientific tool, but engineers from the University of Sheffield in the UK have been using them to identify where waste water from baths, washing machines, sinks and showers is polluting our rivers and streams.

Spring plankton bloom hitches ride to sea's depths on ocean eddies
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar 'greening' event --a massive bloom of microscopic plants, or phytoplankton -- unfolds each spring in the North Atlantic Ocean from Bermuda to the Arctic.
