A technique using satellites to create twice-yearly elevation maps of US mountain glaciers provides new insight into thinning of glaciers in the lower 48 states.
A Nature Communications study, led by Germany's University of Tuebingen and published Oct. 20, demonstrated how composting of biochar creates a very thin organic coating that significantly improves the biochar's fertilizing capabilities.
A fossilized skeleton of a tyrannosaur discovered in Utah's Grand Staircase-Escalante National Monument was airlifted by helicopter Oct. 15, and delivered to the Natural History Museum of Utah where it will be uncovered, prepared, and studied. The fossil is approximately 76 million years old and is likely an individual of the species Teratophoneus curriei.
It turns out that sex can move mountains. A Washington State University researcher has found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. His studyis one of the first to quantitatively show that salmon can influence the shape of the land.
For her Ph.D., Viglietti studied the fossil-rich sediments present in the Karoo, deposited during the tectonic events that created the Gondwanides, and found that the vertebrate animals in the area started to either go extinct or become less common much earlier than what was previously thought.
Living mulch functions like mulch on any farm or garden except -- it's alive. No, it's not out of the latest horror movie; living mulch is a system farmers can use to benefit both profits and the soil. While the system has been around for a while, scientists at the University of Georgia are making it more efficient and sustainable.
In a study published today in the Journal of Geophysical Research Solid Earth, scientists at the University of Utah report that small seismic signals in lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.
Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.
Many birds and other wildlife die following an oil spill, but there are also other potential long-terms effects of oil exposure on animals.
While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis published in Marine Geology shows that the limestone islands of the Bahamas and Bermuda experienced climate changes that were even more extreme than historical events.
