THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal govern- ment on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal govern- ment. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering commu- nities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www. nationa l-academies.org

Preface The polar biological sciences stand on the threshold of a revolution, because the availability of genome sciences and other new enabling tech- nologies has opened the door to study an incredible array of important questions and issues, both fundamental and practical. As this revolution occurs, we will enter a new era that holds the promise of a greatly enhanced understanding of polar ecosystems, their biodiversity, and the interactions of their constituent organisms and communities. Genome sciences is "the study of the structure, content, and evolution of genomes," including the "analysis of the expression and function of both gene and proteins." These approaches will help us to determine not only the organ- isms that are present in polar blames but also to look into their evolution to thrive in extreme cold, their interactions as biological systems, and their capacity to handle global change. Our knowledge of polar eco- systems will become not only global in scope but also more mechanistic in explanation. The Committee on Frontiers in Polar Biology was charged to examine the opportunities and challenges for conducting research on Arctic and Antarctic organisms and ecosystems using genomic technologies. This study was requested by the Office of Polar Programs and the Biology Directorate of the National Science Foundation. Encompassing both poles and essentially all biological disciplines, the task was both stimulating and difficult. I am deeply indebted to my colleagues on the committee, whose breadth of expertise, insights, and selfless efforts have driven this study idea to reality. On behalf of the committee, I also wish to extend my . . V11

vIll PREFACE gratitude to the many biologists (see Appendix C) of all disciplines who participated in our workshop on Frontiers in Polar Biology (September 9-11, 2002~. Their ideas and thoughtful criticism contributed significantly to shaping the committee's thinking and to the generation of this report. This report opens with an Introduction (Chapter 1) to genomics, the paleogeological and paleoclimatic history of the polar regions, the unique features that shape biological and evolutionary processes in polar regions, and a summary of the applicability of genomic technologies to polar biology. Subsequently, we define the key questions in polar biology that are amenable to genomic approaches (Chapter 2~; identify critical species whose genomes, transcriptomes, proteomes, and metabolomes should be analyzed under the aegis of a Polar Genome Science Initiative (Chapter 3~; develop strategies to facilitate interactions and technology transfer within the polar biological community, between polar and nonpolar biologists, and through educational outreach to academic and lay audiences (Chap- ter 4~; and discuss other technologies, facilities, and infrastructure whose development would complement the genome initiative (Chapter 5~. The report concludes with the committee's findings and recommendations for implementation of these ideas (Chapter 6~. The report's recommendations, if implemented, will require increased funding by the National Science Foundation; and we recognize that this may not be an easy decision. Nevertheless, the committee presents an ambitious research agenda. We believe that we are ready to move for- ward: Prior genome projects have developed a strong infrastructure and considerable talent, and the costs for genome-related science are rapidly dropping. We believe that in the near future the commonly heard ques- tion "What is the justification for sequencing the genome of organism Genome species?" will shift to the imperative, "You must sequence the genome of your organisms (or metagenome of an environmental com- munity) so that you obtain a comprehensive understanding of your bio- logical system." The competitive peer review system of the National Science Foundation will ensure that the most rigorous and relevant genome projects are supported and that results of the highest quality are disseminated widely. This report would not exist but for the heroic efforts of the supporting staff of the Polar Research Board: Evonne Tang, Ann Carlisle, Bryan Erickson, and Chris Elfring. They ensured that the committee stayed focused "on goal" through their expertise, tireless support, and efficient marshaling of resources. I believe I speak for the committee when I say that their assistance guaranteed that our participation in this study was both successful and delightful. H. William Detrich III, Chair Committee on Frontiers in Polar Biology

As we enter the twenty-first century, the polar biological sciences stand well poised to address numerous important issues, many of which were unrecognized as little as 10 years ago. From the effects of global warming on polar organisms to the potential for life in subglacial Lake Vostok, the opportunities to advance our understanding of polar ecosystems are unprecedented. The era of “genome-enabled” biology is upon us, and new technologies will allow us to examine polar biological questions of unprecedented scope and to do so with extraordinary depth and precision.

Frontiers in Polar Biology in the Genomic Revolution highlights research areas in polar biology that can benefit from genomic technologies and assesses the impediments to the conduct of polar genomic research. It also emphasizes the importance of ancillary technologies to the successful application of genomic technologies to polar studies. It recommends the development of a new initiative in polar genome sciences that emphasizes collaborative multidisciplinary research to facilitate genome analyses of polar organisms and coordinate research efforts.
