Princeton University-led researchers have extracted 2 million-year-old ice cores from Antarctica that provide the first direct observations of Earth’s climate at a time when the furred early ancestors of modern humans still roamed.
Under a five-year, $25 million Science and Technology Center award, the Center for Oldest Ice Exploration (COLDEX) has been established to address climate change and its impacts.
Scientists think the world's oldest ice is hiding somewhere in Antarctica. NPR science correspondent Nell Greenfieldboyce tells us how researchers plan to find it--and why. NPR Short Wave, Nell Greenfieldboyce, Emily Kwong, Rebecca Ramirez, Jan. 7, 2021. 12-MINUTE LISTEN
The oldest ice on Earth probably is hiding somewhere in Antarctica, because this frozen continent holds ice that's hundreds of thousands and even millions of years old. Scientists are hoping to find it. NPR Science, Nell Greenfieldboyce, Dec. 26, 2020. 5-MINUTE LISTEN
Ever wonder HOW scientists sample ancient air in 🧊? We melt it! The air is then transferred under vacuum and analyzed for its chemical composition. This sample is from the Allan Hills 🇦🇶 and is currently being measured by Dr. Sarah Shackleton. How old is it? Stay tuned! @blueicehiggins WATCH VIDEO
Bubbles of greenhouse gases trapped in ice shed new light on an important climate transition that occurred about a million years ago. EOS, Katherine Kornei.
The Princeton Environmental Institute (PEI) has selected nine graduate students representing six departments and programs as 2019 recipients of the Mary and Randall Hack ’69 Graduate Awards for Water and the Environment, including Higgins Lab grad Jack Murphy.
NSF funding is official - we're going, going, back, back, to...Antarctica...to sleep in a tent for months and drill for Earth's oldest ice. @blueicehiggins
