Spent a week in Oregon w/ Project ICE & COLDEX-Center for Oldest Ice Exploration. From holding 5,000 year old ice & seeing the gases trapped is inside, to sampling a 60,000 year old ice core (& keeping it afterward!), to seeing foraminifera fossils as climate indicators…it was an amazing week! ❤️🧊

اكتشف جليد عمره 6 ملايين عام في القارة القطبية الجنوبية يحطم الأرقام القياسية، ويوجد هواء قديم محصور بداخله
باحثون يقومون بإجراء تدريبات في منطقة آلان هيلز في القارة القطبية الجنوبية. تم دعم هذا العمل من قبل مركز NSF لاستكشاف أقدم الجليد، أو COLDEX. (رصيد الصورة: تصوير جوليا ماركس بيترسون، كولدكس) استخرج العلماء قطعة جليد عمرها 6 ملايين سنة من القارة القطبية الجنوبية - وهي أقدم جليد تم اكتشافه بشكل مباشر على الإطلاق - وهي تساعدهم على إعادة بناء مناخ الأرض القديم. يبلغ عمر الجليد الذي حطم الرقم القياسي، إلى جانب فقاعات الهواء المحبوسة بداخله، أكثر من ضعف عمر أقدم عينات الجليد المعروفة سابقًا، والتي يبلغ عمرها حوالي 2.7 مليون سنة، وفقًا لدراسة جديدة نُشرت في 28 أكتوبر في المجلة.

The NSF COLDEX ice coring team is set up for another field season in the Allan Hills, a windswept region of eastern Antarctica where scientists have found 6-million-year-old ice. Locked inside are the secrets to understanding our ancient climate. I covered COLDEX last year for @sciam.bsky.social:
Inside the Race to Find Earth's Oldest Ice
A global race is on to drill for the oldest known layers of Antarctic ice so researchers can peer back in time to a warmer climate to better understand the planet’s hotter future

AAAS: "Oldest ever ice offers glimpse of Earth before the ice ages." Most scientists drilling for ice core records of ancient gases target the cenral, deepest parts of Antarctica.

Scientists have found 6-million-year-old ice in Antarctica 🧊—the oldest ever directly dated! It offers rare climate snapshots, revealing 12°C cooling over time. A major leap in understanding Earth’s ancient climate. 🌍🔬 #Antarctica #ClimateHistory #COLDEX

I interviewed a scientist in Antarctica this week, as one does.

The COLDEX project is looking for the world’s oldest ice and the history of climate change.

"When I think about Antarctica, it’s all about sea level rise, and Western Antarctica is the heart of the beast and the crux of our problem.”
