The World’s Tallest Geyser Holds On to Some Secrets

Wall Street Journal
January 15, 2021
More than six years ago, the tallest geyser in the world stopped erupting—as geysers sometimes do—but the giant’s slumber wasn’t permanent...

Yellowstone National Park is an excess of geologic riches, from sweeping volcanic vistas to bubbling caldrons with multicolored irises. But one of its 10,000 thermal features has been capturing everyone’s attention recently: Steamboat Geyser...

Reawakened geyser does not foretell Yellowstone volcanic eruptions

Berkeley News
January 4, 2021
When Yellowstone National Park’s Steamboat Geyser — which shoots water higher than any active geyser in the world — reawakened in 2018 after three and a half years of dormancy, some speculated that it was a harbinger of possible explosive volcanic eruptions within the surrounding geyser basin. These so-called hydrothermal explosions can hurl mud, sand and rocks into the air and release hot steam, endangering lives; such an explosion on White Island in New Zealand in December 2019 killed 22 people...

A quadrillion tons of diamonds lie deep beneath the Earth's surface, scientists say

Hand holding large diamond

July 17, 2018
As it turns out, diamonds in the Earth are much more common than we thought. About 1,000 times more common, according to the Massachusetts Institute of Technology. A new study by an interdisciplinary team of researchers used seismic technology (the same kind used to measure earthquakes) to estimate that a quadrillion tons of diamonds lie deep below the Earth's surface...

Scientists Discovered a Quadrillion Diamonds Hidden Deep Within the Earth

Glittering diamonds

July 16, 2018
Adorning an ear or encircling a finger, a n atural diamond is synonymous with luxury. The average cost of a diamond engagement ring is about $6,000, which is a lot of cash for a tightly bound piece of carbon. A new study in Geochemistry, Geophysics, Geosystems, however, points out that the value of diamonds would be very different if humans had better access to the subterranean world...

Princeton University News
June 27, 2018
By applying new data and Princeton’s supercomputers to the classic question of what lies beneath our feet, Princeton seismologist Jessica Irving and an international team of colleagues have developed a new model for the Earth’s outer core, a liquid iron region deep in the Earth...

Advancing Geoscience Research through CIDER

Grad students with laptops

GSA Today
May 2017
With growing technical sophistication in the earth sciences and increasing specialization within its subdisciplines, geoscientists face an organizational problem when we want to tackle grand research challenges that span many disciplines. How do we bring the various fields together to leverage their individual strengths and create something more than the sum of the parts? This is the problem that CIDER (Cooperative Institute for Dynamic Earth Research) attempts to solve...

Explorers Find Passage to Earth’s Dark Age



December 22, 2016
In August, the geologist Matt Jackson left California with his wife and 4-year-old daughter for the fjords of northwest Iceland, where they camped as he roamed the outcrops and scree slopes by day in search of little olive-green stones called olivine...
