Our initial pilot cores, taken in 1998 and 2003, provided proof of concept, demonstrating the importance of these cores as a climate record, as they contain climate data that extend back in time 300,000 years &mdash; roughly three times longer back in time than the oldest portions of the Greenland ice core records.</p> https://www.earthmagazine.org/article/thrill-drill-chill/ Thu, 05 Jan 2012 06:41:58 -0500 https://www.earthmagazine.org/article/thrill-drill-chill/ <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/thrill-drill-chill/i-3e5-7da-7-14.jpg" alt="Sunrise at the scientists&#39; field camp on the western shore of Lake El&#39;gygytgyn.

Within minutes, the impact formed an 18-kilometer-wide hole in the ground that then filled with water. The sediments that collected in the bottom of that lake since the impact may provide one of the best stratigraphic records of high-latitude climate change over the last 3.6 million years. Last year, we traveled to this remote region <a href="http://www.geo.umass.edu/lake_e/index.html">to drill into these sediments</a> to see what we could learn about Arctic change.</p>
