A meteorite crash 3.6 million years ago leaves a deep long climate record.
Considering that the research site was a lake 62 miles north of the Arctic Circle in northeast Siberia, Russia, I didn’t think the topic would turn to mountains. Yet I’ve found a new love for mountains. Everything is interconnected. Lake E project Lake El-gygytgyn sits in a crater that formed 3.6 million years before present […]
Imagine standing on the top floor of the Empire State Building. Above you, the frigid ice-capped waters of a lake in Siberia. Below you sits nearly a quarter of a mile of lake sediment resting atop impact breccia, a layer of rock formed when a meteorite slammed into Earth 3.6 million years ago. Graph wiggles […]
WHERE IS LAKE EL’GYGYTGYN? Monday, December 8th 2014, watch the FrontierScientists science special about drilling for ancient climate data by tuning in to 360 North. Watch over the air from Alaska, or watch online from anywhere in the world by visiting 360North.org at 5am UTC. This 30 minute installment features real scientists and their cutting edge work. […]
Laura Nielsen for Frontier Scientists – Paleoclimatology is the study of past climates. One of the many ways to study paleoclimatology is to collect a 2.5 inch [6.6 centimeter] wide tube of mud from a well-situated site. It’s amazing how much we can learn of Earth’s climate past – and what those findings teach us […]
Laura Nielsen for Frontier Scientists – There’s a place in Northeast Russia where, 3.6 million years ago, a meteorite slammed into Earth. A lake filled the crater. Today, the sediment that has settled at the bottom of Lake El-gygytgyn provides a rare preserved climate record: the longest sediment core record ever collected on land in […]
July 10, 2012– “To this point no one has much of any terrestrial record anywhere in the Arctic older than 125,000 years ago” said Julie Brigham-Grette, University of Massachusetts Amherst as she describes findings from the Lake El’gygytgyn (or Lake E) project to Office of Polar Programs Board Meeting at the National Science Foundation. Brigham-Grette […]
Deep under a frozen lake in Siberia, Russia, lies a researcher’s gold: an astounding record of past climates preserved in untouched layers of lake bed sediment. In 2009 an international team of scientists headed to Lake El’gygytgyn (pronounced El’geegitgin). They perched specialized drilling equipment atop the icy lake surface and drilled down. At the bottom […]
