Subglacial Antarctic Lake Environments (SALE): A Unifying Phenomenon in Antarctic Earth Science

Beneath Antarctica's ice sheets, water has slowly accumulated over millenia pooling in catchment basins within the continental bedrock. Antarctic subglacial environments are natural macrocosms that, in some instances, trace their origins to more than 35 million years before present, when the continent became encased in ice. Life, especially microbial life, has successfully radiated into most aquatic habitats on Earth. There is little reason to doubt that subglacial environments are exempt from this process.The exploration and study of subglacial environments provides an unparalleled opportunity to advance our understanding of how the expression of life, the environment, climate evolution, and planetary history have combined to produce the world as we know it today.

ITASC is a decentralized network of individuals and organisations working collaboratively in the fields of art, engineering and science on the interdisciplinary development and deployment of renewable energy, waste recycling systems and sustainable architecture to enable the production and distribution of open-format, open-source remote field research in Antarctica and the Arctic. ITASC is a lichen-like structure sharing and integrating local knowledge, resources and skills across seven continents in order to symbiotically engage with the air, ocean, earth and space commons.

The project will provide the most comprehensive account so far of the types, amounts, and location of the on-and off-shore biological and mineral resources, including oil and gas, of northern and Arctic Russia from northern Norway in the west to the Bering Strait in the east. How can these resources be exploited sustainably over the next 10-20 and 20-40 years to ensure the economic development and social welfare of the regions concerned and their peoples?

The central idea of NOMAD is the establishment of a mobile observation platform. This is facilitated by a nomadic tent camp that houses an interdisciplinary group of researchers. They follow the annual migration of semi-domesticated reindeer in Kola Peninsula, Northwest Russia. This is a novel effort, putting social and other scientists on the reindeer trek on a long-term basis. By positioning themselves in close contact with migrating reindeer herds the researchers observe the delicate ecology and conditions of renewable resource use in the subarctic. Updates on the progress of the project, photographs and fieldwork diary entries can be found on this website.

There is now clear evidence that the effects of recent and past climate changes have varied in magnitude across of the world. Some changes over periods of thousands of years seem to have affected the Arctic and Antarctic regions alternately, and this has been called the “bipolar see-saw” effect. The BIPOMAC project will collect and examine climate records in sedimentary sequences spanning the past five million years from both polar regions. These records will provide a basis for analysing the complex interactions of environmental processes that have caused the observed patterns of climate variation. Improved understanding of such processes and their interactions will increase our ability to forecast future climate and sea level change.

“Environmental Monitoring: an Indigenous Perspective” is a four-day forum scheduled for 2007 (fall), in Ottawa. It will provide an opportunity for Inuit and other Indigenous Peoples to voice their issues and concerns on the monitoring of their environment. The forum will demonstrate how the capacity, knowledge and viewpoints of Indigenous Peoples can guide environmental monitoring and decision-making processes in the Arctic.

OASIS will study the chemistry in the air over the Arctic Ocean. The health of mammals and humans is at stake, and a future change in climate will undoubtedly introduce unknown changes. OASIS will make use of a variety of platforms (icebreakers, ice islands, buoys) to obtain year-round information on the behavior of such key chemicals as ozone, mercury, and carbon dioxide. As the nature and extent of snow and ice cover is changing OASIS will assess the associated impact on, and by, climate change, and the human and ecosystem impacts of these chemicals.

Global Warming will have a large impact on glaciers in the Arctic region. Sea level will be affected, and substantial changes can be expected in sediment and fresh water supplies to embayments and fjords. In GLACIODYN we study the dynamics of Arctic glaciers by means of field observations, remote sensing from satellites, and computer modelling. This will deliver tools to make more accurate predictions about future changes.

Trace metals iron, zinc, copper, manganese, nickel and cobalt are essential for every living cell and organism of our planet. Recently we discovered that algae in the Southern Ocean, the basis of the entire Antarctic food-chain up to penguins and whales, suffer from a lack of dissolved iron for their growth and CO2 fixation. The role of the other metals in Arctic and Antarctic oceanic waters is virtually unknown. We will quantify distributions, role and fate of several trace metals. Combination with key natural isotopes allows the unraveling of sources and turnover rates of these Trace Elements and Isotopes in waters and ice of the polar oceans.

The Arctic Ocean environment is undergoing tremendous changes over the last decreased with shrinking sea ice cover and increased freshwater run-off and coastal erosion. The documentation of the current state of Arctic marine biological diversity is urgently needed to understand and evaluate the impact of climate change. The Arctic Ocean Diversity project (ArcOD) is an international collaborative effort to inventory biodiversity in the Arctic's three realms (sea ice, water column and sea floor) from the shallow shelves to the deep basins.
