Geologists are interested in the sedimentary cycle – erosion from mountains that forms sand that is carried out to the ocean – because it’s foundational for understanding how the planet works.
Cornell University researchers have unearthed precise, microscopic clues to where magma is stored, offering a way to better assess the risk of volcanic eruptions.
Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 ⁰C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This “terrestrial amplification” of future warming has real-world implications for understanding and dealing with climate change.

In their new paper for the Geological Society of America journal Geology, Dulcinea Groff and colleagues used radiocarbon ages (kill dates) of previously ice-entombed dead black mosses to reveal that glaciers advanced during three distinct phases in the northern Antarctic Peninsula over the past 1,500 years.
Current models of sea level rise suggest the most widespread impacts will occur after sea level has risen by several meters. But a new study finds the biggest increases in inundation will occur after the first 2 meters (6.6 feet) of sea level rise, covering more than twice as much land as older elevation models predicted.
A team of researchers led by Brian Yellen, research professor of earth, geographic, and climate sciences at the University of Massachusetts Amherst, recently announced in the Journal of Geophysical Research: Earth Surface that salt marshes, critical habitats threatened by rapid sea-level rise, may in fact thrive despite higher water levels.
It's often assumed that island plant and animal populations are just the simple, fragile cousins of those on the mainland.
Nearly 100 million years ago, the Earth experienced an extreme environmental disruption that choked oxygen from the oceans and led to elevated marine extinction levels that affected the entire globe.
When the rigid plates that make up the Earth’s lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet’s surface. Strike-slip faults, such as the San Andreas Fault in California or the Denali Fault in Alaska, are among the most well-known and capable of seriously powerful seismic activity.
The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth science.
Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA.
The Martian meteorite Tissint contains a huge diversity of organic compounds, found an international team of researchers led by Technical University of Munich and Helmholtz Munich’s Philippe Schmitt-Kopplin and including Carnegie’s Andrew Steele.
The more-than 1.2 million km of fibre-optic cables that criss-cross the planet carry the world’s phone calls, internet signals and data.

The Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development, to offer virtual “dry run” experiences and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.

KICT and Deltares conducted a research on prediction of the future changes in river landscapes using an eco-morphodynamic model applied to an actual river. According to the study result, the vegetation cover increases continuously until 2031, and the area covered by willow trees occupies up to 20% of the river area.
Louis Urtecho and his team hope to study dust devils in the Mojave Desert on Earth, then extend the analysis to scale for the different atmosphere on Mars. Based on microbarometer data from the Mojave, they built an algorithm to look for the pressure activity indicative of a dust devil. The vortices have a distinct drop in pressure near their centers, and their pressure fluctuates to look like an electrocardiogram signal over time. The team hopes to learn more about the convective vortices and how they move, which will improve the accuracy of Martian weather models.
In Physics of Fluids, researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.
