Machine learning techniques may help scientists better understand the intricate chemistry of streams and monitor broader environmental conditions, according to a team of researchers.
A combination of a once-debunked 19th-century identification of a water-carrying iron mineral and the fact that these rocks are extremely common on Earth, suggests the existence of a substantial water reservoir on Mars, according to a team of geoscientists.
Every year the GBGM executive committee selects exceptional scholars to receive awards for their accomplishments in research, education/mentoring, and service in geobiology.
Jennifer Macalady, professor of geosciences, has been appointed director of Penn State’s Ecology Institute, effective July 1. She holds an appointment in the Department of Geosciences in Penn State’s College of Earth and Mineral Sciences.
Alan Taylor, professor of geography and ecology, will serve as interim director of the Penn State Earth and Environmental Systems Institute (EESI) while director Susan Brantley is on sabbatical. His appointment began July 1.
In March 2020, daily life in the United States changed in an instant as the country locked down to deal with the initial wave of the COVID-19 pandemic. New research reveals how residents in one community returned to their routines as the restrictions lifted, according to a team of Penn State scientists.
Over the last decade, geothermal energy has progressed throughout the world as an environmentally friendly, sustainable source of energy. Using the heat from the Earth’s crust, geothermal power plants harvest and store energy in massive underground reservoirs carved out of stone. Once built, the reservoirs are inaccessible and monitored remotely — but not infallible. Earthquakes and more can fracture the subsurface rock, risking the integrity of the reservoir and endangering energy production.
Ancient pollen samples and a new statistical approach may shed light on the global rate of change of vegetation and eventually on how much climate change and humans have played a part in altering landscapes, according to an international team of researchers.
"We know that climate and people interact with natural ecosystems and change them," said Sarah Ivory, assistant professor of geosciences and associate in the Earth and Environmental Systems Institute, Penn State. "Typically, we go to some particular location and study this by teasing apart these influences. In particular, we know that the impact people have goes back much earlier than what is typically accepted as the case. However, we haven't been able to observe the patterns created by these processes globally or long-term."
Susan L. Brantley, distinguished professor of geosciences and director of the Earth Environmental Systems Institute at Penn State, has been elected a member of the American Academy of Arts and Sciences. The 2021 class of members contains 252 new members who join the more than 13,500 members who have been elected since the Academy was founded in 1780 by the country's founders.
What does research about the early Earth, the tectonics of the Alps and the collapse of ancient mountains have in common? Understanding of all these important Earth processes can benefit from an advanced mineral dating technique conducted in a new Penn State facility for the first time.
