Shows how melting ice is affecting supplies of nutrients to the sea
The findings of a research expedition to coastal Greenland which examined, for the first time, how melting ice is affecting supplies of nutrients to the oceans has been published in the journal Progress in Oceanography. The European Research Council-funded expedition on board the RSS Discovery took place during the summer of 2017.

Mineral Discovery Made Easier: X-Ray Technique Shines a New Light on Tiny, Rare Crystals
Berkeley Lab scientists participate in the discovery of ognitite; other candidate new-mineral studies in progress Like a tiny needle in a sprawling hayfield, a single crystal grain measuring just tens of millionths of a meter - found in a borehole sample drilled in Central Siberia - had an unexpected chemical makeup.

How tides can trigger earthquakes
How tides can trigger earthquakes
An international team of scientists - including a volcanologist from the University of Bristol - have uncovered why underwater earthquakes are linked with the tides. Their study, published , investigates the inner workings of tidally triggered earthquakes and found that even the slightest stress can set off a tremor.

Dwarf planet Ceres: a new form of volcanism found
An international research team solves the mystery of how the mountain Ahuna Mons on Ceres was probably formed / Study in "Nature Geoscience" The scientists could hardly believe their eyes when they first saw this formation on the images acquired by their Framing Camera on board the Dawn space probe: a symmetrical mountain over 4000 metres tall and with steep, smooth sides rising over the crater-strewn surface of.

Mysterious Holes in Antarctic Sea Ice Explained by Years of Robotic Data
The winter ice on the surface of Antarctica's Weddell Sea occasionally develops an enormous hole. In 2016 and 2017, one such hole drew intense curiosity from scientists and the media. Though bigger gaps had formed decades before, this was the first time oceanographers had a chance to truly monitor the unexpected gap in Antarctic winter sea ice.

How deep-ocean vents fuel massive phytoplankton blooms
How deep-ocean vents fuel massive phytoplankton blooms
A new study suggests vents in the seafloor may affect life near the ocean's surface and the global carbon cycle more than previously thought. It's the first to show how iron rising from beneath Earth's crust stimulates massive phytoplankton blooms. Researchers at Stanford University say they have found an aquatic highway that lets nutrients from Earth's belly sweep up to surface waters off the coast of Antarctica and stimulate explosive growth of microscopic ocean algae.

Seismologists seek space on volunteers' floors and lawns to study Seattle seismic risks
Seismologists seek space on volunteers’ floors and lawns to study Seattle seismic risks
The Puget Sound area is vulnerable to several types of seismic risks. We might fixate on "The Really Big One” - the offshore hazard famously profiled in The New Yorker - but other dangers lurk closer underfoot, and might actually deliver more damage to Seattle. The nature of the ground beneath the city - a roughly 4-mile-deep basin filled with soil and soft rock - makes the urban core especially vulnerable to seismic shaking.

Uncovers Surprising Melting Patterns Beneath Antarctica’s Ross Ice Shelf
In a study published today a team of scientists, including glaciologists from Scripps Institution of Oceanography at the University of California San Diego, detail how they discovered an ancient geologic structure under Antarctica's largest ice shelf and describe how the ice shelf's stability in future climates depends on local processes occurring in summer near the ice front.

Ancient seawater preserved from the last Ice Age
Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller-shorelines extended hundreds of miles farther out, and the remaining water was saltier and colder.

Hot spots in rivers that nurture young salmon 'flicker on and off' in Alaska's Bristol Bay region
Hot spots in rivers that nurture young salmon ’flicker on and off’ in Alaska’s Bristol Bay region
Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska's most productive salmon populations, and the fisheries they support, depend on the entire watershed. Sockeye and Chinook salmon born in the Nushagak River and its network of streams and lakes in southwest Alaska use the whole basin as youngsters when searching for the best places to find prey, shelter and safety from predators.

Source of new CFC emissions discovered
Source of new CFC emissions discovered
Since 2013, annual emissions of the banned chlorofluorocarbon CFC-11 have increased by around 7,000 metric tons from eastern China, according to a new study by an international team of scientists including Empa researchers, published in «Nature» today. The new discovery follows a finding in 2018 that emissions of this very important ozone-depleting substance had increased.

Source of new CFC emissions
Since 2013, annual emissions of a banned chlorofluorocarbon (CFC) have increased by around 7 Australia and Switzerland. Last year, it was reported that emissions of one of the most important ozone depleting substances, CFC-11, had increased. This chemical was used primarily as a foaming agent for building insulation, refrigerators and other consumer products.

Geologists discover previously unknown region of the Earth's mantle
Geologists discover previously unknown region of the Earth’s mantle
The Bermuda Islands - a very special terrain in the middle of the western Atlantic Ocean, not only for its white beaches, but also because the archipelago is at the top of a 4,570-metre high volcano that died out about 30 million years ago. An international team of researchers has now taken a closer look at this geological peculiarity and geochemically examined the magma rock under Bermuda for the first time.

3D Earth in the making
15 May 2019 A thorough understanding of the 'solid Earth' system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains and the location of underground natural resources.

Concludes Glassy Menagerie of Particles in Beach Sands Near Hiroshima is Fallout Debris from A-Bomb Blast
Mario Wannier, a career geologist with expertise in studying tiny marine life, was methodically sorting through particles in samples of beach sand from Japan's Motoujina Peninsula when he spotted something unexpected: a number of tiny, glassy spheres and other unusual objects. Wannier, who is now retired, had been comparing biological debris in beach sands from different areas in an effort to gauge the health of local and regional marine ecosystems.

Chewing versus sex in the duck-billed dinosaurs
Chewing versus sex in the duck-billed dinosaurs
The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 tonne giants so successful? A new study, published in Paleobiology, shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved.

Dr. Benjamin Bomfleur on finding a reptile footprint in the Antarctic
Around three years ago, researchers on an Antarctic expedition, including Münster University palaeobotanist Dr. Benjamin Bomfleur , made an incredible discovery in northern Victoria Land. They found the 200 million-year-old footprint of an extinct reptile. The researchers have now published their findings from the hand-sized footprint in the journal “Polar Research”.

Data mining digs up hidden clues to major California earthquake triggers
Comprehensive new earthquake catalog includes 10 times more quakes than previously identified, with a more detailed picture of stresses and structures in the earth A historic image of quake damage in Long Beach, California, 1933. CREDIT: W.L. Huber, USGS (Public domain) It's very difficult to unpack what triggers larger earthquakes because they are infrequent, but with this new information about a huge number of small earthquakes, we can see how stress evolves in fault systems.
