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 […]

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 […]
