More than 100 years of flooding and erosion in one event

Sara Rathburn of Colorado State University and colleagues have developed an integrated sediment, wood, and organic carbon budget for North St. Vrain Creek in...

Rocks that tell our industrial history

Researchers in the UPV/EHU's Department of Analytical Chemistry have published a study in which they analyse cemented sand formations that contain industrial waste produced...

Amazon River no younger than 9 million years

Researchers from the University of Amsterdam (UvA) and the University of Brasilia (Brazil) have determined the age of the formation of the Amazon River...

Last remnant of North American ice sheet on track to vanish

The last piece of the ice sheet that once blanketed much of North America is doomed to disappear in the next several centuries, says...

Going deep to measure Earth’s rotational effects

Researchers in Italy hope to measure Earth's rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable effects of...

Study shows how river channels adjust to large sediment supplies

The seemingly simple question of what governs the shapes of river channels has been a longstanding challenge for geologists and civil engineers. A new...

Snow and sand erosion explained

Scientists at EPFL and SLF describe with precision how snow and sand surfaces erode when exposed to wind. Their description can contribute to better...

Study opens new questions on how the atmosphere and oceans formed

A new study led by The Australian National University (ANU) has found seawater cycles throughout Earth's interior down to 2,900km, much deeper than previously...

From rocks in Colorado, evidence of a ‘chaotic solar system’

Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists from the University of Wisconsin-Madison and Northwestern University has...

Old rocks, biased data: Overcoming challenges studying the geodynamo

Gleaning data from old rocks may result in bias. Now, geophysicists have a way to improve their methods to overcome challenges in studying the...

‘Firefall’ phenomenon wows visitors to Yosemite’s El Capitan

Mother Nature is again putting on a show at California's Yosemite National Park, where every February the setting sun draws a narrow sliver of...

Shifting monsoon altered early cultures in China, study says

The annual summer monsoon that drops rain onto East Asia, an area with about a billion people, has shifted dramatically in the distant past,...

Largest undersea landslide revealed on the Great Barrier Reef

James Cook University scientists have helped discover the remnants of a massive undersea landslide on the Great Barrier Reef, approximately 30 times the volume...

A Rusty Green Early Ocean?

Though they may seem rock solid, the ancient sedimentary rocks called iron formations -- the world's chief economic source of iron ore -- were...

Earth’s orbital variations, sea ice synch glacial periods

Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher...

Researcher examines plants encased in tar pits to reconstruct ice age...

For tens of thousands of years, the warm, sticky natural asphalt that occasionally bubbled to the Earth's surface in the area now called Los...

Doubt over Everest’s true height spurs fresh expedition

Scientists will take the tape measure to Mount Everest to determine whether a massive earthquake in Nepal really did knock an inch off the...

Caves in central China show history of natural flood patterns

Researchers at the University of Minnesota have found that major flooding and large amounts of precipitation occur on 500-year cycles in central China. These...

Researchers find seafloor valleys below West Antarctic glaciers

Glaciologists have uncovered large valleys in the ocean floor beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved...

Conditions right for complex life may have come and gone in...

Conditions suitable to support complex life may have developed in Earth's oceans -- and then faded -- more than a billion years before life...
