Henry Horn, professor of ecology and evolutionary biology, emeritus, a scholar and fervent naturalist for whom Princeton’s campus and the surrounding areas provided a rich biosphere for study, died suddenly March 14 at Princeton. He was 77.
A new paper from a team of researchers claimed that it is possible to dim the sky in such a way that no region of the planet will be made significantly worse. The scenario may sound like science fiction, but the debate over the prudence of this technique—called solar geo-engineering—has already begun.
The Simon Foundation has granted Assistant Professor of Geosciences and at the Princeton Environmental Institute Prof. Xinning Zhang a Simons Early Career Investigator in Marine Microbial Ecology and Evolution Award for the period of 2019-2022.
Princeton geoscientists Blair Schoene and Gerta Keller led an international team of researchers who have assembled the first high-resolution timeline for the eruptions in India’s Deccan Traps. Their research appears in the Feb. 22 issue of the journal Science.
Laure Resplandy, an assistant professor in Geosciences and Princeton Environmental Institute, awarded prestigious 2019 Sloan Research Fellowship, a highly competitive grant given to outstanding young scholars working at the frontiers of their fields.
Professor Tom Duffy’s research group has been awarded experimental time on Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) to explore the nature of minerals deep in the interior of rocky extrasolar planets.
Seismologists Jessica Irving and then-graduate student Wenbo Wu (who just defended his thesis last month!) used earthquake waves measured after a 1994 magnitude 8.2 earthquake to find underground mountains, at the bottom of the mantle’s “transition zone,” located 660 kilometers straight down.
Mesoscale eddies — the storm systems of the oceans — mix water masses and are crucial for the transport of heat, salt, carbon and nutrients in the global oceans. In this study, researchers find that the mixing effects of mesoscale eddies at the surface vary strongly in time, connected to fluctuations in the large scale climate like e.g. ENSO. This could be a new climate feedback mechanism that is currently not represented in global climate models.
Earth has a song, a symphony composed of ubiquitous, continuous subtle seismic signals that thrum beneath the hustle and bustle of modern society. The term “ambient seismic noise” is the “classic nomenclature found in scientific literature,” often used to describe both microseisms and seismic hum, although “these are not synonyms,” says Lucia Gualtieri, a postdoctoral research associate in geophysics at Princeton University.
A startling study says that devastating storms that intensify rapidly are becoming more common. In the new study, the researchers used two separate data sets of storm behavior to analyze changes in the tendency of hurricanes to rapidly intensify.
