Dr. Fahnestock received a B.S. in Geology from the University of Rochester in 1984 and a doctorate in Geology from the California Institute of Technology in 1991. Since that time, he has worked as a glaciologist investigating ice flow mechanics and surface conditions on the large ice sheets. After studying Alaskan glaciers as a graduate student, he moved to NASA Goddard Space Flight Center to investigate surface conditions and ice flow in Greenland and Antarctica. He took a position at the University of Maryland in 1995, working as an Assistant Research Scientist in a cooperative center for Earth System Science (now the Earth System Science Interdisciplinary Center). He started at the University of New Hampshire in May 2002.
His research focuses the role of land-based ice in the earth system. Results from work with numerous collaborators have included the recognition of a large ice stream in northeast Greenland and of the rapid basal melting likely responsible for this rapid ice flow; the first high-resolution radar mosaic of an ice sheet, illustrating both flow features and firn conditions on a large scale; development of a relationship between surface melting and the failure of ice shelves on the Antarctic Peninsula; contributions to the use of InSAR for mapping ice-flow velocity and surface topography; techniques for mapping detailed topography from visible-band satellite imagery; the recent history of ice flow variations on the Ross Ice Shelf mapped from enhanced imagery; and work on the controls on rapid ice flow in Antarctica and Greenland. He has also contributed to work on measuring ice discharge in Greenland and has participated in two Antarctic and four Greenland field excursions. His recent interests focus on the controls underlying rapid ice flow and on atmospheric interactions that determine surface conditions on the large ice sheets. The primary tools for this work are satellite-derived and surface observations and interactions with ice sheet modelers.
Recent community service includes sitting on the Alaska SAR Facility Users Group, an NRC committee to advise NASA about Polar Geophysical Data Sets, the Radarsat Antarctic Mapping Project Scientific Advisory Group, the scientific steering committee for NSF ARCSS Arctic-CHAMP (pan-Arctic Community-wide Hydrological Analysis and Monitoring Program) and serving as an Associate Editor for JGR Atmospheres.
Dr. Green is an associate professor of anthropology at the University of Arizona and Director of the Center for Latin American Studies. She received her MA and Ph.D. from the Department of Anthropology at the University of California, Berkeley. Dr. Green also received a Master in Public Health from The Johns Hopkins University.

Her work attempts to trace historical shifts in vulnerability, particularly among peoples across the Americas whose primary identity is indigenous. Dr. Green conducts field research in rural Guatemala, the U.S.-Mexico border, and rural Alaska. Her monograph Fear as a Way of Life: Mayan Widows in Rural Guatemala was published by Columbia University Press (1999) is soon to be published in Spanish in Guatemala.
To Die in the Silence of History: Tuberculosis among Yup’ik peoples of southwestern Alaska is in manuscript preparation. This 3-year ethnographic and archival research project, funded by the National Science Foundation, explores the social consequences of the tuberculosis epidemics that ravaged Native communities, especially the Yukon-Kuskokwim Delta region during the mid-twentieth century. The manuscript highlights the social consequences of the tuberculosis epidemics of the twentieth century that have been largely overlooked in understanding contemporary Yup’ik lives.
Dr. Green current research, The Invisible Wounds of War, also funded by the National Science Foundation, examines the ways in which Yup’ik combat veterans from Native villages across southwestern Alaska reintegrate into communities with the accompanying stresses of combat. This research seeks to grasp the human and social consequences of war on Yup’ik men’s lives who have served in combat in the U.S. military from three eras — the Vietnam War, the First Gulf War, and the ongoing conflicts in Iraq and Afghanistan.
Dr. Hofmann is a professor in the Department of Ecology, Evolution and Marine Biology at the University of California, Santa Barbara. She and her research group take an integrative approach to the study of ecophysiology, with a focus on the responses of marine organisms to environmental climate change stressors such as temperature and oceanic pH. Over the past decade, research in the Hofmann lab has emphasized the use of physiology and genomic tools to determine effects of ocean acidification (OA) on key calcifying invertebrate species. In particular, Dr. Hofmann has focused on Antarctic marine ecosystems and other sensitive marine regions where organisms may be especially vulnerable to the potential effects of global change.
Another major component of Dr. Hofmann’s research is the use of integrative physiological approaches to measure responses of invertebrates to climate related stressors and the possible mechanisms behind those responses. With emphasis on early life history stages, ongoing research includes examination of morphological responses to OA and temperature in polar and temperate urchins (O’Donnell et al., 2010; P. Yu, unpubl.), respiration and energetics, fertilization kinetics (Sewell et al., in prep; Dutton et al., in prep), calcification rates, enzyme activities, protein expression (Hammond and Hofmann, submitted) and biochemical content (Matson et al., in prep). Techniques, such as qPCR, microarrays and next-generation sequencing (454 and Illumina platforms), are also being employed to study transcriptomic responses in both model and non-model marine invertebrates. Together, the integration of these various indices help generate a more complete understanding of physiological challenges to homeostasis during the early life history of marine calcifying organisms under future climate change conditions.
Dr. Hofmann is the Director of the Center for the Study of Ocean Acidification and Ocean Change, a University of California multi-campus research and training initiative. She also serves on the steering committee for the California Current Acidification Network (C-CAN), a collaborative effort between scientists and members of the West Coast shellfish industry. Dr. Hofmann was an Aldo Leopold Fellow in 2009 and serves as the Co-chair for the Ocean Carbon and Biogeochemistry (OCB) Ocean Acidification Committee.
