National Research Council’s Committee on Geophysical and Environmental Data and was previously a U.S. Representative of the Scientific Committee on Antarctic Research. He is a member of the American Meteorological Society, the American Geophysical Union, the Royal Meteorological Society, and the American Association of Geographers. Dr. Bromwich earned his Ph.D. in meteorology from the University of Wisconsin, Madison, in 1979.

Richard Glenn is the vice president of lands for the Arctic Slope Regional Corporation. His professional experience includes petroleum geological studies, field geological mapping, structural geological and seismic interpretation, permafrost, methane hydrate, and borehole temperature profile research. Other specialties include year-round studies of the physical properties of sea ice near Barrow, Alaska; and temperature, salinity and crystallographic profiles of first- and multi-year sea ice and documentation of freeze-up, ice movement events, and spring thaw. He has served as director of the Department of Energy Management, North Slope Borough; general manager of Barrow Technical Services, a technical firm that provided project management consulting and geological and scientific research support services; and a geologist for the Arctic Slope Consulting Group. Mr. Glenn is a member of the Ilisagvik College Board of Trustees, board president of the Barrow Arctic Science Consortium, and former member of the U.S. Arctic Research Commission. Mr. Glenn is an Alaska native and earned his master’s in geology from the University of Fairbanks.

David Karl is a professor of oceanography at the University of Hawaii. His research interests include marine microbial ecology, biogeochemistry, long-term time-series studies of climate and ecosystem variability, and the ocean’s role in regulating the global concentration of CO₂ in the atmosphere. Dr. Karl is a member of the Polar Research Board. He earned his Ph.D. in oceanography from the Scripps Institution of Oceanography, University of California, San Diego, in 1978.

Peter Schlosser is the Vinton Professor of Earth and Environmental Engineering and professor of Earth and Environmental Sciences at Columbia University and senior research scientist at the Lamont-Doherty Earth Observatory. He also is the associate director of the Earth Institute at Columbia University. He received his Ph.D. in Physics from the University of Heidelberg, Germany, in 1985. Dr. Schlosser’s research interests include studies of water movement and its variability in natural systems (oceans, lakes, rivers, groundwater) using natural and anthropogenic trace substances and isotopes as “dyes” or as “radioactive clocks”; ocean/atmosphere gas exchange; reconstruction of continental paleotemperature records using groundwater as an archive; and anthropogenic impacts on natural systems. He participated in seven major ocean expeditions, five to the polar regions. He was or presently is a member or chair of national and international science steering committees, including the World Ocean Circulation Experiment, the Climate Variability and Predictability Experiment, the World Climate Research
