**************************************************************************** Announcing the 2008 Kleinman Grants for Volcano Research From: Daniel Dzurisin <dzurisin@xxxxxxxx> **************************************************************************** The following students have been awarded 2008 Kleinman Grants for Volcano Research. Jack Kleinman was a USGS employee at the David. A. Johnston Cascades Volcano Observatory who died in a kayaking accident in 1994. By supporting field-oriented research projects in volcanology, the Kleinman Grants memorialize Jack's exuberance for fieldwork, volcanoes, and the natural world in general. During the past 14 years, the program has helped dozens of aspiring volcanologists who seek to learn more about volcanoes and how they work. Dan Ruscitto, Isolde Belien, Nick Deardorff, Daniele McKay, and Natalia Deligne are Ph. D. students in the Department of Geological Sciences, University of Oregon. Their joint research proposal is titled "A collaborative approach to understanding effusive and explosive volcanism of intermediate composition in the Central Oregon Cascades." Together with their research advisor, Dr. Katharine Cashman, they will undertake an intensive field study of Collier Cone and Four-in-One Cone at the Three Sisters volcanic center in the central Oregon Cascade Range. The goals of the research are to study: (1) lava-channel formation, surface morphology, and geomorphic characteristics that might derive from the interaction of lava with surface water; and (2) tephra deposits from both cones to tie together the physical aspects of the eruption with the chemical nature of the erupted material. Alison Koleszar is a Ph.D. student in the Department of Geosciences at Oregon State University. Her project is "Volatile (H2O, CO2, S, Cl, F) concentrations in calc-alkaline andesites from Mount Hood Volcano, Oregon." She will analyze silicate melt inclusions within olivine, pyroxene, amphibole, and plagioclase phenocrysts to determine whether low volatile contents are consistent with low explosivity of Mount Hood lavas, and to study the influence of volatile concentrations on the eruption and emplacement of Mount Hood lava flows and domes. Alison's adviser at OSU is Dr. Adam Kent. Colleen Donegan is enrolled in the Master's degree program in the Department of Geology at Northern Arizona University. Her thesis topic is "Dendrochronological responses to the eruption of Mount St Helens, Washington." With her adviser, Dr. Michael Ort, Colleen will attempt to identify and understand certain chemical changes that are expressed in tree rings affected by the 1980 eruption at Mount St. Helens. Such changes have been documented at basaltic cinder cones elsewhere, but their cause is poorly understood. Coleen will collect and analyze both cores and soil samples from tress that survived the 1980 eruption. Marco Bagnardi is a Masters degree student in the Department of Earth Sciences at the University of Rome. His thesis project is "Mass intrusion beneath Kilauea Volcano, Hawaii, constraints from geodetic and gravity measurements." Marco, who is working under the supervision of Prof. Maurizio Battaglia, will make microgravity measurements at Kilauea and analyze the results together with ground-deformation data acquired by the USGS Hawaiian Volcano Observatory. The goal of the project is to constrain the depth, shape, and material properties of magma storage areas beneath the Kilauea's summit area. Congratulations to this year's Kleinman Grant recipients! We look forward to hearing about your results at scientific meetings and reading about them in the research literature. ________________________________________ Dr. Daniel Dzurisin U.S. Geological Survey David.
