WWU student earns 2011 Kleinman Grant for Volcano Research

Announcing the 2011 Kleinman Grants for Volcano Research

The Community Foundation for Southwest Washington announces that Julie Gross, a geology grad student at WWU’s geology department, has been awarded the Kleinman Grant  for Volcano Research.

Julie’s  thesis topic is “Felsic magmas from Mount Baker in the northern Cascade arc: origin and role in andesite production”. The origin and evolution of dacitic
magmas in volcanic arcs such as the Cascades is a topic of ongoing debate
among volcanologists. Julie will study three dacite lava flows at Mount
Baker: the dacite of Cougar Divide, dacite of Nooksack Falls, and dacite
of Mazama Lake. She will use major and trace element analyses from
minerals and whole rock samples to model whether fractionation of Mount
Baker basalts and andesites could have produced these dacites, or whether
some other origin is indicated.

Congrats to Julie, who joins a long line of WWU students to receive this grant. Past recipients at the department include Steve Shaw (2010), Niki Moore (2007), Troy Baggerman,  Brendan Hodge, and Angie Diefenbach (all in 2006), Kristin Hill Johnsen (2005) and Dave Tucker (1998). Stephen Slaughter, who did his undergraduate studies at WWU, was awarded a Kleinman in 2003 while a Masters student at Central Washington University.

If you received a Kleinman at WWU and I left you out, please let me know.

Jack Kleinman

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. During the past 16 years, the program has helped dozens of
aspiring volcanologists who seek to learn more about volcanoes and how
they work. The grant is awarded by a panel of scientists at Cascade Volcano Observatory.
Other recipients this year:
Kenneth Befus is a Ph.D. student at the University of Texas at Austin (Dr.
James Gardner, thesis adviser; Drs. Jacob Lowenstern and Lisa Morgan, USGS
advisers). His thesis topic is “The significance of granophyre in
Solfatara Plateau lava flow, Yellowstone Volcanic Field”. Ken plans to map
the distribution of granophyre in the Solfatara Plateau rhyolite flow and
to collect and analyze samples in order to investigate what factors
influence the explosivity of rhyolite eruptions. Specifically, what clues
might the granophyre provide into the differences between highly explosive
caldera-forming eruptions and relatively non-explosive, effusive eruptions
that produce lava flows such as the Solfatara Plateau flow?

Meagan Bosket is an M.Sc./Ph.D. candidate at the University of
Wisconsin-Madison (Dr. Clark Johnson, thesis adviser; Dr. Charles Bacon,
USGS adviser). Her thesis topic is “Tracing the build-up to the
caldera-forming eruption (7.7 ka) at Mount Mazama, Crater Lake, Oregon”.
Meagan will sample ash from the caldera-forming eruption and use
uranium-series isotopic analyses to investigate magmatic processes and
timescales associated with the eruption. Her ultimate goals are to address
the question of why a large reservoir of highly explosive magma developed
at Mount Mazama, relative to other volcanoes in the Cascade Range, and to
explore implications for future caldera-forming eruptions in the Cascades.

Katy Chamberlain is a Ph.D. candidate at the Victoria University of
Wellington, New Zealand (Drs. Colin Wilson and Joel Baker, thesis
advisers). Her thesis research is focused on reconstructing conditions in
the magma reservoir that produced the widespread Bishop Tuff deposit,
which was emplaced during highly explosive eruptions responsible for
formation of the Long Valley caldera 760,000 years ago. Katy will sample
stratigraphically-controlled pumices from the Bishop Tuff eruption and
examine the minerals present using advanced imaging and analytical
techniques. Her goal is to establish the pre-eruptive state of the magma
reservoir and to follow the processes that gave rise to the climactic
eruption

Owen Neill is a Ph.D. student at the University of Alaska Fairbanks (Drs.
Pavel Izbekov and Jessica Larsen, thesis advisers; Drs. William Scott and
Chris Waythomas, USGS advisers). His thesis topic is “Vesiculation and
fragmentation processes during the August, 2008 eruption of Kasatochi
volcano, central Aleutian Islands, Alaska”. Owen will participate in a
research excursion to remote Kasatochi volcano to collect samples of
pumice from the 2008 eruption. He will examine vesicle populations in
polished thin sections and measure magmatic volatile contents in melt
inclusions in order to determine what processes and factors contributed to
the eruption’s unusually high energy release.

Congrats to all from MBVRC.
