A small team of earth scientists and engineers will be using a specialized drill to reach buried ice deposits in the Dry Valleys region of Antarctica. Stagnant and/or slow moving debris-covered glaciers may contain ice several million years in age. By comparison, the oldest ice yet cored from the East Antarctic Ice Sheet is approximately 1 million years old. As a result, these buried ice deposits hold an ancient archive of Earth’s past atmospheric conditions. Each ice core will enable the research team to gain access to a reliable record of atmospheric and climatic change extending back for many millions of years, making it by far the oldest ice yet known on this planet.
