Researchers from Cornell University and the National Park Service have pinpointed and confirmed the location of the remnants of a wooden fort in Alaska – the Tlingit people’s last physical bulwark against Russian colonization forces in 1804 – by using geophysical imaging techniques and ground-penetrating radar.
There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka's Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years.
Microscopic bubbles can tell stories about Earth's biggest volcanic eruptions and geoscientists from Rice University and the University of Texas at Austin have discovered some of those stories are written in nanoparticles.
Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.
CSU geology experts study the active land California inhabits to better understand earthquakes and predict the location and intensity of future temblors.
Around 1085 AD, along the southern rim of Northern Arizona's elevated Colorado Plateau, a volcano erupted, forever changing ancient Puebloan fortunes and all nearby life.
Researchers describe development of a near-real time spatial assessment of COVID-19 cases to help guide local medical responses to clusters of outbreaks of the virus at the local level. The paper, entitled “Geographic monitoring for early disease detection (GeoMEDD),” appeared in the Dec. 10 issue of Nature Scientific Reports.

A study by the University of Southampton gives a new perspective on why our planet has managed to stay habitable for billions of years - concluding it is almost certainly due, at least in part, to luck.
Despite its tropical-sounding name and exotic-tasting In a recent article in Plant Ecology, Associate Professor The pawpaw is extremely rare in New York State, with only 20 known locations. Stephen Tulowiecki, a geographer at SUNY Geneseo, studied the conditions that pawpaws favor, and developed a model to predict locations where pawpaws may grow and identify areas that might sustain newly introduced trees.
The Last interglacial period was the last warm period before our present Holocene age and dates back some 129,000 to 116,000 years ago.
At a North Carolina beach, researchers have been poking and prodding the sand to study how moisture levels affect sounds as they move across the environment. Over short distances, even moderately wet sand reflects sound more like water does than as a solid surface does. Faith Cobb and her team are looking into if the same is true for long-range sound propagation. Their findings will be presented as a part of the 179th ASA Meeting.
Using a trained neural network and data from the North Anatolian Fault in Turkey, a research team led by Los Alamos National Laboratory revealed the first direct observation of rupture propagation during a slow earthquake.
While offshore wind projects provide clean and renewable energy, a new study from the University of Delaware shows that they can also have unintended effects on local weather in the form of minimal, though statistically significant, impacts when it comes to wind speed and reduced precipitation at nearby onshore locations.
A small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists presenting the findings Monday, 7 December at AGU's Fall Meeting 2020.
Scientists using a unique combination of capabilities at the Advanced Photon Source have learned more about how meteorites affect one of the most abundant materials in the Earth’s crust.
In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.
The number of wildfires and the amount of land they consume in the western U.S. has substantially increased since the 1980s, a trend often attributed to ongoing climate change.
Methane, the main component of natural gas, is the cleanest-burning of all the fossil fuels, but when emitted into the atmosphere it is a much more potent greenhouse gas than carbon dioxide.
In a new book, “Has It Come to This? The Promises and Perils of Geoengineering on the Brink,” Holly Jean Buck and colleagues weigh in on social, ethical and political dimensions of deliberate, large-scale interventions in the planet’s climate.
It will come as no surprise to anyone living in Phoenix, Arizona, that 2020 has been a record-breaking year for high temperatures.
Floods of unimaginable magnitude once washed through Gale Crater on Mars’ equator around 4 billion years ago – a finding that hints at the possibility that life may have existed there, according to data collected by NASA’s Curiosity rover and analyzed in joint project by scientists from Jackson State University, Cornell University, the Jet Propulsion Laboratory and the University of Hawaii.
The COVID-19 pandemic had surprising effects on demand for public transit in American cities, new research suggests. While demand for public transit dropped about 73% across the country after the pandemic hit, the reduction didn’t impact all cities equally.
Geology student Sam Ocon is fulfilling her dream of studying invertebrate paleontology.
In a study that gives new meaning to the term "rock bottom," seismic researchers have discovered the underside of a rocky slab of Earth's surface layer, or lithosphere, that has been pulled more than 400 miles beneath northeastern China by the process of tectonic subduction.
For the first time, state and federal wildlife biologists have come together to map the migrations of ungulates - hooved mammals such as mule deer, elk, pronghorn, moose and bison - across America's West.
The emergence of life is a mystery. Nevertheless, researchers agree that water is a precondition for life. The first cell emerged in water and then evolved to form multicellular organism. The oldest known single-cell organism on Earth is about 3.5 billion years old.
After more than two years of joint research, Lawrence Livermore National Laboratory (LLNL), Total, and Stanford University are releasing an open-source, high-performance simulator for large-scale geological carbon dioxide (CO2) storage.
Maintaining forest cover is an important natural climate solution, but new research shows that too often, communities lose out when local forest management is formalised.
Diverse microbes discovered in the clay-rich, shallow soil layers in Chile’s dry Atacama Desert suggest that similar deposits below the Martian surface may contain microorganisms, which could be easily found by future rover missions or landing craft.
International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active -- erupting for 30 million years -- fuelled by a constantly moving 'conveyor belt' of magma.
Planetary scientists from Brown University have developed a new remote sensing method for studying olivine, a mineral that could help scientists understand the early evolution of the Moon, Mars and other planetary bodies.
Global warming of 2°C would lead to about 230 billion tonnes of carbon being released from the world's soil, new research suggests.
Mega-droughts - droughts that last two decades or longer - are tipped to increase thanks to climate change, according to University of Queensland-led research.
Stromboli, the ‘lighthouse of the Mediterranean’, is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as ‘Strombolian paroxysms’. During such events several of Stromboli’s craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano.
Between 57 and 55 million years ago, the geological epoch known as the Paleocene ended and gave way to the Eocene. At that time, the atmosphere was essentially flooded by the greenhouse gas carbon dioxide, with concentration levels reaching 1,400 ppm to 4,000 ppm. So it's not hard to imagine that temperatures on Earth must have resembled those of a sauna.
Humankind’s next giant step may be onto Mars. But before those missions can begin, scientists need to make scores of breakthrough advances, including learning how to grow crops on the red planet.
In a recent paper published in Nature Communications, Mousavi and co-authors describe a new method for using artificial intelligence to bring into focus millions of these subtle shifts of the Earth. "By improving our ability to detect and locate these very small earthquakes, we can get a clearer view of how earthquakes interact or spread out along the fault, how they get started, even how they stop," said Stanford geophysicist Gregory Beroza, one of the paper's authors.
If you think that the Sahara is covered only by golden dunes and scorched rocks, you aren't alone.
Simple actions can dramatically improve a person’s chances of surviving a landslide, show records from 38 landslides in the U.S. and around the world. People who survived landslides tended to have moved upstairs or to higher ground, among other key actions.
There are places that will always be beyond our reach. The Earth's interior is one of them.
The existence of a tectonic plate called Resurrection has long been a topic of debate among geologists, with some arguing it was never real. Others say it subducted - moved sideways and downward - into the earth's mantle somewhere in the Pacific Margin between 40 and 60 million years ago.
A pioneering technique which captures precisely how mountains bend to the will of raindrops has helped to solve a long-standing scientific enigma.
Cold temperatures keep the microorganisms in permafrost dormant. Thawing could cause these microorganisms to degrade organic material, releasing carbon dioxide and methane. Scientists have now studied the diversity and metabolic capacity of microbial communities in a unique permafrost environment.
