4. Biological and Environmental Research Mission • To understand complex biological, climatic, and environmental systems across spatial and temporal scales. • BER provides the foundational science to: • Support the development of biofuels as major, secure, and sustainable national energy resources • Understand the potential effects of greenhouse gas emissions on Earth’s climate and biosphere and the implications of these emissions for our energy future • Predict the fate and transport of contaminants in the subsurface environment at DOE sites • Develop new tools to explore the interface of biological and physical sciences

5. Biological and Environmental Research Approach • Understanding complex biological and environmental systems across many spatial and temporal scales: • From the sub-micron to the global • From individual molecules to ecosystems • From nanoseconds to millennia • Integrating science by tightly coupling theory, observations, experiments, models, and simulations • Supporting interdisciplinary research to address critical national needs • Engaging national laboratories, universities, and the private sector to generate the best possible science

13. Climate Change and Permafrost Ecosystems • Goal: advance the predictive understanding of the structure and function of Arctic terrestrial ecosystems in response to climate change • Objectives: • Understand processes/feedbacks governing these complex systems • Design and deploy combination of observations and manipulative experiments to test model-inspired hypotheses • Resulting knowledge improves models, resulting in improved climate predictions Approach • Collaborative effort among DOE National Laboratories and universities, led by Oak Ridge National Laboratory • Interdisciplinary, multi-scale approach to advance predictive understanding through iterative experimentation and modeling • Opportunities for leveraging through external collaboration (DOE and other agencies)
