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.

Climate warming is resulting from disruption of the global carbon (C) cycle. The Arctic is already warming significantly and the region governs some critical feedbacks in global change, including release of huge C stores from high-latitude soils, shift in albedo due to changes in vegetation and snow cover, and potential effects on the thermohaline circulation as a result of alterations in river discharge to the Arctic Ocean. However, the links between climate, the C cycle, energy balance, and hydrology are complex and our understanding of them – and their impact on Arctic ecosystems – is poor. ABACUS aims to provide answers to these critical questions.

The Overarching problems to be adressed by the project relates to the impact of globalization, privatization and liberalization. The Arctic regions still in most cases are characterized by economic dependence on centres in the South, which dominate trade patterns and capital movements. Hence, the main research question is related to both positive and negative impacts of the global economy

The polar environments are rapidly changing and leaving a lasting impact on the freshwater and terrestrial ecosystems within them. However the region is so vast and diverse that the knowledge of what drives these changes is limited. This project will assess how terrestrial and freshwater ecosystems and environments have changed in the past and record their current status and biodiversity. IPY provides a timely opportunity for passing on knowledge to new generations of researchers and forming a new and authoritative baseline of environmental characteristics with which to examine future changes. Among the sites to be studied are some first examined during the ICSU-sponsored International Biological Programme, which will allow some assessment of changes over recent decades.

There is increasing recognition that multiple environmental changes are occurring in the northern regions of Europe. Some of these environmental changes, for example climate warming, levels of UV-B radiation, and habitat fragmentation, are projected to continue leading to impacts on the lands of the Nordic countries unprecedented since deglaciation some 10,000 year ago. Three ENVISNAR projects studying these processes are profiled below:

The present project integrates natural and socioeconomic sciences in describing past, natural variability of multi-year-ice (Storis) and its impact on present and future activities in the coastal communities in South and East Greenland. Both regions, but the south Greenland region in particular, is characterized by a complex composition of activities.
