About this Blog

This blog is dedicated to a research expedition to the McMurdo Dry Valleys in Antarctica. Through field mapping of geomorphic evidence, sample collection, and cosmogenic nuclide concentration measurements in the Noble Gas Lab at Harvard, we hope to better understand the behavior of the East Antarctic Ice Sheet during Miocene (~23 to 5 million years ago) and Pliocene (~5-1.8 mya) times. The Early Pliocene is the most recent period in which global temperatures were significantly warmer than the present, therefore providing us with a potential analog for a warming climate. This research is generously funded by the NSF Polar Science Program.
