This project links together multidisciplinary interests in the region of West Antarctica where the ice sheet discharges into the Amundsen Sea. It is one of the most active ice sheet areas, is already contributing a significant fraction of the increasing sea level, and holds the potential to dwarf other sea level contributions in the future. Aside from routine satellite coverage that monitor elevation and surface features, information about the area is limited. Our project will greatly advance our knowledge of ice dynamics of the area, the basal conditions, sub-shelf oceanic interactions, atmospheric transport of incoming snow, and historical record of ice extent. These studies will be conducted with the direct intention of supplying the involved modeling experts with necessary data to construct, initialize and validate advanced full-stress tensor models of ice flow.

ANDRILL (ANtarctic geologic DRILLing) is a multinational collaboration of over 200 scientists, drillers, engineers, technicians, students and educators from Germany, Italy, New Zealand and the United States. The goal is to recover long stratigraphic records along the continental margins of Antarctica by drilling from an ice shelf or sea ice platform. By interpreting these sedimentary rock records, scientists can understand how Antarctica’s ice sheet has advanced and retreated over time. The ANDRILL website has a fantastic range of information for scientists, teachers, and media.

Even though climate change is dramatically affecting the biosphere, our understanding of its effects on biological communities is poor. The Southern Ocean is an ideal natural laboratory to the impact of regional and global climate change because of the sensitive interactions between temperature, ice extent and species. Measuring variations in penguin populations can tell us a great deal about climate change, but could tell us even more if we understood the mechanisms the underlie the dynamics of penguin colonies. Taking advantage the major advances that have been made in microelectronics recently, this project will fit penguins with hugely powerful yet tiny state-of-the-art transponders and data recorders. The project will provide the first complete global and unified picture of penguin population dynamics, uncovering the processes that drive their numbers and the effects climate change is having on them.
