Deep learning artificial intelligence keeps an eye on volcano movements
10/14/2020

 RADAR satellites can collect massive amounts of remote sensing data that can detect ground movements — surface defomations — at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements.

Now, Penn State researchers have used artificial intelligence (AI) to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest.


Climate impacts could put major fishery, food security at risk in East Africa
10/12/2020

Climate change could put a major fishery — and the millions of people who depend on it — at risk in one of the world’s most vulnerable regions, according to researchers.

“Fisheries are important to food security throughout the world,” said Sarah Ivory, assistant professor of geosciences at Penn State. “Developing nations, like those surrounding Lake Tanganyika in eastern Africa, depend on fish as an important protein source. It’s also an important part of their cultural identity.”


After an asteroid wiped out the dinosaurs, ocean microbes helped life rebound

Never underestimate pond scum. The asteroid impact that killed most of the dinosaurs 66 million years ago also created conditions for ocean microbes to flourish, according to a new study. In microscopic rock crystals, researchers have found evidence that massive blooms of algae and photosynthetic bacteria covered the world’s oceans, providing food for larger marine creatures soon after the cataclysm.


Students work to educate Pennsylvanians about benefits of renewable energy
09/08/2020

 Penn State students are working virtually on the Pennsylvania Solar Center’s Renew PA Works campaign in an effort to educate Pennsylvanians about the benefits of renewable energy, including job creation. The opportunity is made possible through City Semester, an internship program facilitated by the Penn State Center Pittsburgh, a Penn State Outreach service.


Wauthier awarded NSF CAREER award to investigate volcanic flank instability
08/26/2020

Christelle Wauthier, associate professor of geosciences in the College of Earth and Mineral Sciences, received a Faculty Early Career Development Program (CAREER) Award from the National Science Foundation to develop numerical models to characterize volcanic flank instability processes.

 


COVID-19 doesn’t curb field camp 'rite of passage' for geosciences students
08/21/2020

In a field exercise, geosciences student Katie Reilly moved from point to point, analyzing surface geological formations, hoping to gain insight into the environmental conditions that formed portions of the Rocky Mountains.

For experienced undergraduate students in Penn State's College of Earth and Mineral Sciences, this capstone field camp is a rite of passage. Each year, dozens of students usually spend six weeks exploring the topography and geologic features of the Western United States, analyzing firsthand the expression of forces that they’ve spent years learning.


Geoscientist's professorship to drive research on landscapes, hazards
08/21/2020

Roman DiBiase won’t soon forget the name of an early mentor when he began his career at Penn State in 2014.

He was recently named the Rudy L. Slingerland Early Career Professor of Geosciences, a distinction that honors the now retired Penn State professor and will help fund DiBiase’s research studying how landscapes erode over geologic time, shaping mountains and in an instant leading to hazards from fires, floods and landslides.


Seismic waves help scientists 'see' chemical changes beneath a watershed
07/29/2020

UNIVERSITY PARK, Pa. — Chemical reactions deep below ground affect water quality, but methods for “seeing” them are time-consuming, expensive and limited in scope. A Penn State-led research team found that seismic waves can help to identify these reactions under an entire watershed and protect groundwater resources.

“About one third of the U.S. population gets their drinking water from groundwater, so we need to protect this valuable resource,” said Susan Brantley, distinguished professor of geosciences and director of the Earth and Environmental Systems Institute (EESI) at Penn State. “At this point, however, we don’t know where the water is or how it moves in the subsurface because we don’t know what is down there. In this study we used human-generated seismic waves — similar to the waves from earthquakes — to look under the surface.”


Photos may improve understanding of volcanic processes
07/21/2020

The shape of volcanoes and their craters provide critical information on their formation and eruptive history. Techniques applied to photographs — photogrammetry — show promise and utility in correlating shape change to volcanic background and eruption activity.

Changes in volcano shape — morphology — that occur with major eruptions are quantifiable, but background volcanic activity, manifesting as small volume explosions and crater wall collapse, can also cause changes in morphology and are not well quantified.


Greenland bedrock drilling project to understand past, future ice sheet melting
07/20/2020

The Greenland Ice Sheet holds enough water to raise sea levels nearly 24 feet, yet it remains difficult to predict the rate of melt and possible tipping points in the stability of the ice sheet.

Climate change is now causing Greenland to shed ice rapidly, and even a few feet of sea level rise may have grim implications for coastal cities and low-lying islands. A new project aimed at drilling through the ice to the underlying bedrock promises to reveal the ice sheet’s past in unprecedented detail and enable more accurate predictions of how it may add to rising seas in the 21st century.
