Reference number : GC-2017-Q1-01495, amendment number : , agreement type : G, recipient legal name : Jellinek, Andrew (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Discovery Grants Program - Individual, program name french : Programme de subventions à la découverte - individuelles, program purpose english : Since the destruction of Pompeii in AD 79, volcanic hazards in the form of devastating pyroclastic flows have captured the attention and imaginations of scientists and non-scientists alike for generations. The global economic consequences of the long-lived ash cloud related to the relatively small Eyjafjallaj&ouml;kull eruption in the spring of 2010, however, caught the world off guard entirely and demonstrated gaps in our understanding of eruption dynamics, as well as new challenges for assessing risks in an increasingly globalized world. That the Little Ice Age, which led to famines and associated vast population declines across Europe between 1300 and 1850, is now best explained as a consequence of novel climate effects related to extensive explosive volcanism particularly concentrated around the Pacific rim makes unease related to the 2010 event more acute. 
 
Through 12 tasks involving experimental, theoretical and computational studies of novel aspects of the dynamics of volcanic eruptions, as well as complementary field and remote sensing studies, this proposal will make critical progress on 2 major thematic questions: 
 
 Do volcanic eruptions modulate or even drive centennial to millenial climate variability with potentially dramatic societal consequences such as the profound European famines that occurred during the &ldquo;Little Ice Age&rdquo;? 
 
 Are seismic tremors related to pre-eruptive magma flow reliable precursors of dangerous eruptions, and are these dynamics expressed in the behavior of, and deposits from, eruption plumes? 
 
Progress on each thematic question shares the challenge of resolving and understanding small-scale processes related to the dynamics of particle-fluid mixtures, as well as recognizing their expression in varied geological and geophysical data. My lab is uniquely positioned to make progress. In addition to an established recent record of quantitative field studies, the continuing success of my experimental geological fluid mechanics program motivated construction of the state-of-the-art EOAS Geophysical Fluid Dynamics Laboratory (GFDL), which opened in 2012/13, and formed the basis for establishing a successful CFI John Evans Leadership Fund-supported Centre for Geophysical Mixing in the Earth System (CGMES) in 2015/2016. CGMES includes critical infrastructure dedicated to resolving mixing processes in particle-laden flows at all scales of interest. This proposal leverages these capabilities along with my established breadth of experience in volcanology, geodynamics, mantle-climate coupling, planetary science and Earth systems science. This work will train 5 PhD students and 2 MSc students to identify and address cutting edge scientific problems and to carry out work using varied and innovative technical methodologies. In addition, I will involve 10-15 undergraduates at 2nd, 3rd and 4th year (i.e., theses) levels in all aspects of the work., program purpose french : Since the destruction of Pompeii in AD 79, volcanic hazards in the form of devastating pyroclastic flows have captured the attention and imaginations of scientists and non-scientists alike for generations.
