Expeditions

U.S. ice scientists travel to Antarctica, Greenland, and mountain ranges around the world to conduct fieldwork in some of the harshest conditions on Earth. Below you can find information about current and upcoming fieldwork as well as completed fieldwork.

Greenland: Climate Drivers and Ancient History in Greenland Ice

Using the Foro 400 Drill, this project will drill a 400-450 meter long ice core from the Tunu region of northeast Greenland and analyze the core for a broad range of elements, chemical species, and isotopes to reconstruct climate and human impacts during the past ~4000 years. An ice-penetrating radar survey extending 40-km upstream along the ice-flow line upstream of the ice-core site will support interpretation of the aerosol and water isotope records, as well as understanding of any possible impacts from changes in deposition processes upstream. The goal of this research is to develop accurately dated, high-resolution, ice-core records of a broad range of elements and chemical species to expand and extend recently identified, causal linkages between (1) ancient societies; (2) volcanism and hydroclimate; and (3) wars, plagues, social unrest, and economic activity.
