The department is excited to announce that the W. Jason Morgan lecture “Fifty years of Plate Tectonics” is available for public viewing.  Princeton University has set up a Department of Geosciences playlist on their Youtube channel.  This will allow the department to produce videos intended for a broader audience via the internet.
In a paper published today by Nature Astronomy, a team of researchers from Lawrence Livermore National Laboratory (LLNL), Princeton University (Duffy Research Group), Johns Hopkins University and the University of Rochester have provided the first experimentally based mass-radius relationship for a hypothetical pure iron planet at super-Earth core conditions. This discovery can be used to evaluate plausible compositional space for large, rocky exoplanets.
GEO Undergrad Alec Getraer writes about studying the natural sciences at Princeton and how that can be a significant undertaking regarding independent research projects. He talks about his experience in taking the course "GEO/WRI 201: Methods in Data Analysis & Scientific Writing" and how he felt that it was a unique course designed specifically to teach students how to write an independent scientific paper.
The Department of Geosciences and Princeton University congratulates Dr. Yajun Peng on successfully defending his Ph.D. thesis: "Seismological Observations and Numerical Modeling of Slow Earthquakes" on Monday, March 26, 2018.
In new shock-compression experiments at an x-ray synchrotron, Sally June Tracy and colleagues, observed that SiO2 transforms from an amorphous material to a tetragonal crystal at a pressure of 36 GPa.
The 2015 Paris climate agreement sought to stabilize global temperatures by limiting warming to “well below 2.0 degrees Celsius above pre-industrial levels,” but a recent literature review found the 2 degree limitation “inadequate” and concluded that limiting global warming to no more than 1.5 degrees would “come with several advantages.”
Have you ever wished you could travel inside a rock? It may sound more like the Magic School Bus than science, but Princeton scientists have found a way to make it (almost) true.  With an industrial grinder and a super-high-resolution camera, Princeton geoscientists Adam Maloof and Akshay Mehra can deconstruct rock samples and create three-dimensional digital versions that scientists can look at from any angle.
The Witwatersrand Basin in southern Africa began as a shallow sea about 3 billion years ago. Scientists analyze this water to learn how microbes make a living when trapped kilometers beneath the surface. DCO Deep Energy and Deep Life Community members: Thomas Kieft (NMT), Verena Heuer (UNI-Bremen), Esta van Heerden (UFS), Barbara Sherwood Lollar (UToronto), and Maggie C.Y. Lau and Tullis Onstott (Princeton) investigated the organic matter in fracture waters to find clues to how they survive.
Climatologists are often asked, “Is climate change making hurricanes stronger?” but they can’t give a definitive answer because the global hurricane record only goes back to the dawn of the satellite era. But now, an intersection of disciplines — seismology, atmospheric sciences and oceanography — offers an untapped data source: the seismic record, which dates back to the early 20th century.
Join Wagner Free Institute of Science in Philadelphia for a hands-on, Ice Age-themed day of activities, scavenger hunts and demonstrations that teach about a fascinating period of Earth’s history. During the afternoon, geochemist Prof. John A. Higgins will be in their historic lecture hall presenting his research team's recent ice core studies in Antarctica and what they tell us about the Ice Age. Register ahead.
