Greenland glacial meltwaters rich in mercury
Greenland glacial meltwaters rich in mercury
New research shows concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding raising questions about the effects of glacial melting in an area that is a major exporter of seafood. "There are surprisingly high levels of mercury in the glacier meltwaters we sampled in southwest Greenland," said lead author Jon Hawkings, a postdoctoral fellow at Florida State University and the GFZ German Research Centre for Geosciences.

Energy unleashed by submarine volcanoes could power a continent
Energy unleashed by submarine volcanoes could power a continent
Volcanic eruptions deep in our oceans are capable of extremely powerful releases of energy, at a rate high enough to power the whole of the United States, according to research published today. Eruptions from deep-sea volcanoes were long-thought to be relatively uninteresting compared with those on land.

Scientists zero in on the role of volcanoes in the demise of dinosaurs
Scientists zero in on the role of volcanoes in the demise of dinosaurs
Researchers have uncovered evidence suggesting that volcanic carbon emissions were not a major driver in Earth's most recent extinction event. Even though volcanic carbon emissions alone couldn't have triggered the mass extinction, our data highlights their influence on our planet's climate and habitability Sally Gibson Earth has experienced five major extinction events over the last 500 million years, the fifth and most recent responsible for wiping out the dinosaurs 66 million years ago.

New basalt type discovered beneath the ocean
New basalt type discovered beneath the ocean
A new type of rock created during large and exceptionally hot volcanic eruptions has been discovered beneath the Pacific Ocean. An international team of researchers including from the University of Leeds unearthed the previously unknown form of basalt after drilling through the Pacific Ocean floor. The discovery suggests that ocean floor eruptions sourced in the Earth’s mantle were even hotter and more voluminous than previously thought.

Seafloor nutrient vital in global food chain
Seafloor nutrient vital in global food chain
Eroded seabed rocks are providing an essential source of nutrition for drifting marine organisms at the base of the food chain, according to new research. The findings, led by the University, show that iron – an essential nutrient for microscopic marine algae known as phytoplankton – is being released from sediments on the deep ocean floor.

Melting glaciers could speed up carbon emissions
Melting glaciers could speed up carbon emissions
Melting glaciers could be triggering a 'feedback process' that causes further climate change, according to new research. An international research team led by the University has for the first time linked glacier-fed mountain rivers with higher rates of plant material decomposition, a major process in the global carbon cycle.

Lightning strikes played vital role in origins of life on Earth
Lightning strikes played vital role in origins of life on Earth
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say. Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet. Scientists believed minimal amounts of these minerals were also brought to early Earth through billions of lightning strikes.

Traces of Earth's early magma ocean identified in Greenland rocks
Traces of Earth’s early magma ocean identified in Greenland rocks
New research led by the University of Cambridge has found rare evidence - preserved in the chemistry of ancient rocks from Greenland - which tells of a time when Earth was almost entirely molten. It's astonishing that we can even hold these rocks in our hands - let alone get so much detail about the early history of our planet Helen Williams The study, published in the journal Science Advances , yields information on an important period in our planet's formation, when a deep sea of incandescent magma stretched across Earth's surface and extended hundreds of kilometres into its interior.

New African groundwater maps reveal widespread resilience to climate change
New African groundwater maps reveal widespread resilience to climate change
Reserves of groundwater in much of the populated parts of Africa are being replenished at rates that could help to protect communities against the damaging effects of climate change, finds a new study co-authored by UCL. Published in the journal Environmental Research Letters , the study has revealed that the long-term groundwater recharge (the rate at which groundwater is replenished) in Africa is approximately 15,000 cubic km per decade - enough to sustain widespread groundwater pumping for drinking water and irrigatation for farming.

Emissions of banned ozone-depleting substance are back on the decline
Emissions of banned ozone-depleting substance are back on the decline
Global emissions of a potent substance notorious for depleting the Earth's ozone layer - the protective barrier which absorbs the Sun's harmful UV rays - have fallen rapidly and are now back on the decline, according to new research. Two international studies show emissions of CFC-11, one of the many chlorofluorocarbon (CFC) chemicals once widely used in refrigerators and insulating foams, are back on the decline less than two years after the exposure of their shock resurgence in the wake of suspected rogue production.
