Appendix C Committee and Staff Biosketches Committee: Dr. Stephanie Pfirman (Chair) is Alena Wels Hirschorn and Martin Hirschorn Professor in Environmental and Applied Sciences and Chair of the Department of Environmental Science at Barnard College, which she joined in 1993. Current interests include environmental aspects of sea ice in the Arctic, and the development of women scientists and interdisciplinary scholars. Dr. Pfirman is President of the Council of Environmental Deans and Directors, a member of the Polar Research Board of the NAS, and co-PI of the NSF-sponsored Advancing Women in the Sciences initiative of the Columbia Earth Institute. Dr. Hajo Eicken’s interests are in the field of sea-ice geophysics. In particular, he is interested in how small-scale properties and (micro)structure of sea ice impact processes on a larger scale as well as the role of sea ice in the climate system. As part of the International Polar Year (IPY) 2007-2009, Dr. Eicken is part of an international group that is studying the seasonal Arctic ice zone through an observing network. As Professor of Geophysics at the University of Alaska Fairbanks, he is leading a university-wide IPY initiative to promote exchange between scientists and stakeholders. Dr. Thorsten Markus is the Branch Head of the Cryospheric Sciences Branch at NASA Goddard Space Flight Center, Greenbelt, MD. His interests include the remote sensing of the polar regions and the utilization of remote sensing data to study polar processes. He is a member of Aqua AMSR-E Science Team responsible for sea ice concentration and snow on sea ice products, and the ICESat Science Team. He participated in ship-borne and air-borne validation campaigns in both The Antarctic and The Arctic. Dr. Markus is working on utilization of satellite-derived geophysical parameters in data analysis efforts and in data assimilation schemes to explore the role of cryospheric processes in the polar and global climate system. Dr. Walter Meier is an expert on sea ice remote sensing and data assimilation; Arctic climate and climate change. His areas of observational expertise include SSM/I passive microwave polar stereographic sea ice products; visible and infrared products; and field observations. He is currently focused on better understanding the decreasing Arctic summer sea ice cover and its impacts. Dr. Meier is a former professor at the US Naval Academy. Dr. Norbert Untersteiner, originally from Austria, began his polar career during International Geophysical Year (IGY) as the Chief Scientist on Ice Station Alpha in the Arctic Ocean. In a scientific sense, it was one of the most successful science programs during the IGY. He was the organizer and director of Operation AIDJEX (Arctic Ice Dynamics Joint Experiment) the most comprehensive inter-scientific-disciplinary study 33

34 Scientific Value of Arctic Sea Ice Imagery Derived Products of the Arctic Ocean ever attempted from the sea ice. AIDJEX was fielded from March 1975 to May 1976 and involved 125 people living on four ice floes in the central Beaufort Sea. It was extremely successful and became the model of later studies of the Arctic Ocean culminating with Operation SHEBA a follow-on to AIDJEX completed in 1998. He led numerous field operations, and directed numerous science divisions and directorates at the University of Washington, including the Polar Science Center in the Applied Physics Laboratory. He served as chairman of the Department of Atmospheric Science until his retirement in 1997. He was also a member of the Vice President’s (of the USA) Medea Commission. From 1999-2005 was the Sydney Chapman Professor of Physical Science at the University of Alaska. Staff: Curtis H. Marshall is a senior program officer with the Board on Atmospheric Sciences and Climate (BASC). He received B.S. (1995) and M.S. (1998) degrees in meteorology from the University of Oklahoma, and a Ph.D. (2004) in atmospheric science from Colorado State University. His doctoral research, which examined the impact of anthropogenic land-use change on the mesoscale climate of the Florida peninsula, was featured in Nature and the New York Times. Prior to joining the staff of BASC in 2006, he was employed as a research scientist in the National Oceanic and Atmospheric Administration. Since joining the staff of BASC, he has directed peer reviews for the U.S. Climate Change Science Program and staffed studies on mesoscale meteorological observing systems, weather radar, the NPOESS spacecraft, and the impacts of climate change on human health. Ms. Katie Weller is a Research Associate for the Board on Atmospheric Sciences and Climate (BASC). She has worked on National Research Council studies that produced the reports Earth Observations from Space: The First 50 Years of Scientific Achievements, Evaluation of the Multifunction Phased Array Radar Planning Process, and Review of the US Climate Change Science Program’s Synthesis and Assessment Product 3.3, Weather and Climate Extremes in a Changing Climate, among others. In 2004, she received her B.S. from the University of Michigan in Biopsychology. Ms. Weller is currently working toward a master’s degree in Environmental Science and Policy at Johns Hopkins University. Ms. Shelly Freeland is a Program Assistant for the Board on Atmospheric Sciences and Climate (BASC). Since joining BASC in 2008, she has worked on studies and workshops involving climate change, climate, energy and national security, and uncertainty management in remote sensing of climate data. Ms. Freeland is interested in Environmental Science and Engineering, focusing on environmental policies.
