Fjords are 'hotspots' in global carbon cycling
While fjords are celebrated for their beauty, these ecosystems are also major carbon sinks that likely play an important role in the regulation of the planet's climate, new research reveals.
Study of Antarctic ice cores reveals atmospheric CO2 history over past thousand years
200th anniversary of Tambora eruption a reminder of volcanic perils
The 2010 eruption of the Icelandic volcano Eyjafjallajökull grounded thousands of air flights and spread ash over much of western Europe, yet it was puny compared to the eruption 200 years ago of Tambora, ...
Comet dust—planet Mercury's 'invisible paint'
A team of scientists has a new explanation for the planet Mercury's dark, barely reflective surface. In a paper published in Nature Geoscience, the researchers suggest that a steady dusting of carbon from p ...
Researchers find levels of nitrogen in meteorites similar to levels in Earth's atmosphere
Volcanic plumbing at mid-ocean ridges goes far deeper than thought
(Phys.org) —Two-thirds of earth's surface is covered in oceanic crust, but the deep plumbing that generates new crust remains poorly understood. New images from a chain of volcanoes beneath the Pacific ...
Solar dimming caused by air pollution increases river-flows
A study published in Nature Geoscience shows that air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere.
'Just right' plant growth may make river deltas resilient
Research by Indiana University geologists suggests that an intermediate amount of vegetation—not too little and not too much—is most effective at stabilizing freshwater river deltas.
Burrowing animals may have been key to stabilizing Earth's oxygen
Evolution of the first burrowing animals may have played a major role in stabilizing the Earth's oxygen reservoir, according to a new study in Nature Geoscience.
Researchers figure out how oddly shaped sandstone landform structures come about
Melting and refreezing of deep Greenland ice speeds flow to sea, study says
Beneath the barren whiteness of Greenland, a mysterious world has popped into view. Using ice-penetrating radar, researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as ...
Cutoff switch may limit spread, duration of oxygen minimum zones
A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that ...
Study reveals four new man-made gases in the atmosphere
Scientists at the University of East Anglia have identified four new man-made gases in the atmosphere – all of which are contributing to the destruction of the ozone layer.
