Asteroid that wiped out the dinosaurs also triggered a global tsunami
CNN — When a city-size asteroid slammed into Earth 66 million years ago, it wiped out the dinosaurs – and sent a monster tsunami rippling around the planet, according to new research. Dr. Brandon Johnson, of Purdue EAPS, is cited in this article by CNN.
Rainwater collected in the Andes Mountains contains fingerprints of atmospheric processes
The Andes Mountains of Peru hold key evidence of the world’s most precious resource: water. Ice cores on the mountains reveal stable isotope signatures of warm and cold spells in the past and even cave stalactites store information about the water that has poured down over this region for thousands of years. Records from these regions are critical to helping produce climate models. Every piece of this ever-evolving research inches mankind closer to predicting weather patterns world-wide under a changing climate. A team of researchers from Purdue University and the Universidad Nacional de San Augustín de Arequipa in southern Peru teamed up to study rains captured during the wet monsoon season and measure the oxygen and hydrogen stable isotopic ratios of the rainwater. This study of isotopic signatures of different rain generating atmospheric patterns was recently published in the American Geophysical Union's (AGU) Geophysical Research Letters (GRL).
Rare deep earth diamond reveals trapped secrets of the Earth’s interior
Deep in the ground of Botswana, a rare deep earth diamond was unearthed from the Karowe mine. It was buried 660 kilometers beneath the surface of the Earth. Trapped inside this diamond are secrets of our Earth’s history. The inclusions found inside this diamond prove that, even at such an incredible depth, the environment can still be wet.
This discovery was published by Dr. Tingting Gu, adjunct assistant professor of Purdue Earth, Atmospheric, and Planetary Sciences (EAPS) and a team of scientists in Nature Geoscience on September 26, 2022.
Learn why the 2022 hurricane season has taken off
ACROSS THE SKY PODCAST — The second half of hurricane season has exploded, making up for its slow start. Purdue University's Jhordanne Jones, a native of Jamaica whose research focuses on seasonal hurricane forecasting, joins us to talk about why the season started slowly, why it's picking up so rapidly now.
NASA mission that could save humanity
ABC NEWS — ABC News’ Gio Benitez reports on NASA’s first attempt to deliberately crash a space probe into an asteroid 7 million miles away in a critical test of planetary defense capabilities. Dr. Michelle Thompson, of Purdue EAPS, is interviewed about the mission.
