Field Program Goals

Our objective is to drill an ice core to bedrock at Site Beta where the ice thickness is expected to range from 400 to 500 meters. Ice cores, cylinders of ice extracted from the ice field or glacier, contain chemical and physical properties that yield information about the climate and the environment (see figure below), often covering thousands of years. By drilling to the bedrock, we will capture the entire climate history preserved at Site Beta.

If time allows, we will drill three or four more shallow cores (~25 meters deep) and collect near surface (very recent) samples from several pits excavated to roughly 1 or 2 meters.

Ice core layers and the data they can yield
Several types of environmental data can be derived from ice cores.
