Announcing the 2018 Kleinman Grants for Volcano Research
The Community Foundation for Southwest Washington announces that the following students have been awarded 2018 Kleinman Grants for Volcano Research. Jack Kleinman was a USGS employee at the David. A. Johnston Cascades Volcano Observatory (CVO) 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. During the past 23 years, the program has helped dozens of aspiring volcanologists who seek to learn more about volcanoes and how they work.
Jade Bowers is a Ph.D. student at Oregon State University (Shanaka de Silva, adviser) who is conducting a field and laboratory study of Mount Sinabung volcano in northern Sumatra, Indonesia. Sinabung began erupting in 2010 for the first time in recorded history, forcing more than 38,000 people to be displaced or permanently resettled. Jade’s goal is to study the volcanic and magmatic history of Mount Sinabung to improve understanding of associated hazards and of Sinabung’s relation to nearby Toba Caldera. She will collect stratigraphically-controlled samples for age dating and for major-element, trace-element, and isotopic analysis. Her research is being carried out in cooperation with the Indonesian Center for Volcanology and Geologic Hazard Mitigation, Badan Geologi (Geological Agency of Indonesia), and the USGS/USAID Volcano Disaster Assistance Program.
Simona Gabrielli is a Ph.D. student at the University of Aberdeen, Scotland (Matteo Spagnolo, adviser). She plans a field project at Mount St. Helens, Washington, combining geomorphology and geophysics. She has compiled a geomorphological map of the volcano, which she will field-check this summer. A specific focus of the study is the origin of small crater landforms on the Pumice Plain. Simona plans to image the shallow subsurface near several of the craters using a ground penetrating radar to infer stratigraphy, in an attempt to distinguish among different origin possibilities (for example, phreatic explosion or melting of glacial ice blocks). She also plans to examine andesite flows on the volcano’s south flank and the area near Goat Marsh. Her project is being coordinated with Richard Waitt at the USGS Cascades Volcano Observatory.
Thomas Herbst is a Ph.D. student at the University of Missouri (Alan Whittington, adviser). His thesis project is a rheological investigation of silicic lavas in the Lassen Volcanic Center, California. Thomas plans to sample several localities during field work this summer. He will measure and compare the effective viscosities of the 1915 lava dome and flow at Lassen Peak, the silicic domes at Chaos Crags, and older Lassen Peak dacite flows. He will determine bubble, crystal, and water content of each lava and test current models for how these should affect lava rheology, and also measure bulk composition of interstitial glass within dacite samples. His project is being coordinated with Michael Clynne at the USGS California Volcano Observatory.
Ellyn Huggins is a Ph.D. student at the University of Nevada, Reno (Philipp Ruprecht, adviser). Her project is focused at Mount Veniaminof in the Aleutian volcanic arc of Alaska. She plans to study melt inclusions in samples from Veniaminof to better characterize the shallow crust under this large volcanic center, and to estimate magmatic volatile contents and storage depths before eruption. An extensive suite of samples has been collected previously by a team of USGS scientists. Fieldwork at Veniaminof is logistically challenging, so Ellyn plans to study existing samples first to guide more targeted fieldwork by her and others in coming years. The project has been developed in collaboration with USGS scientists Tom Sisson, Charlie Bacon, and Jessica Larsen.
Rachel Warwick is a M.Sc. student at Simon Fraser University, British Columbia, Canada (Glyn Williams-Jones, adviser). Her study area is the Mt. Meager Volcanic Complex in the northernmost part of the Cascade Range in British Columbia, Canada. During field work this summer, Rachel plans to make gas ratio measurements at two fumaroles that were spotted in 2015 breaching the surface of the Job glacier in the northeast section of the volcanic complex. She will also make gravity measurements and conduct a ground penetrating radar survey to calculate ice thickness and ice volume values, which will be used as input parameters to numerically model lahar hazards. Results will be included as part of a first-ever volcanic hazard assessment and hazard map for the Mt. Meager complex.
