Geophysics: http://tinyurl.com/jetgzm5 "We welcome applications from scientists working in all aspects of Geophysics including earth-observation, the cryosphere, planetary geophysics, and crustal processes." Solid Earth Geoscience: http://tinyurl.com/hp3kk42 "We welcome applications from scientists working in all aspects of the solid earth sciences including solid-earth geophysics, igneous processes or petrology, planetary geology, and mineralogy” In 2016, The Times Higher Education ranked Oxford as the top in the world*. In 2014, the UK government's Research Excellence Framework rated Oxford Earth Sciences as the top Department in the UK. My personal view, having been a member of the Department for eight years, is that this is an outstanding place to work. The Department is a friendly, collegial, open and energetic environment with an internationally diverse faculty. We received a Bronze award from Athena Swan*, recognising our commitment to advancing women’s careers. We have a fantastic building that is only six years old — it still feels new. Teaching requirements are reasonable (less than in the USA and France). The undergraduate students are talented and motivated. There is a seminar series that brings in top scientists from around the world. Technical support is excellent, from the many geochemistry labs to the recently hired Senior Research Fellow in Computational Geoscience. The town of Oxford is beautiful and convenient — most people in the Department commute by bike all year. It is a quick bus ride to London Heathrow airport, with direct flights to most major cities in the world. The UK has a generous policy for parental leave, offering up to six months with full pay, which can be shared between parents. The links above provide detailed information about the jobs, but feel free to contact me if you have further questions.

Next week’s webinar on Thursday November 10 @ 2pm PT features Renee Gassmoeller. Rene will be talking to us about a key feature of ASPECT - particle implementation. Don’t miss these insights from an ASPECT expert. Rene Gassmoeller, CSU Fort Collins Particle-in-cell methods have a long history in modeling of mantle convection, lithospheric deformation and crustal dynamics. However, their efficient parallel implementation and application in models - in particular combined with adaptive meshes - is involved due to the complex reassignment of particles to cells and frequent parallel communication. In this webinar, I present the implementation of a flexible, scalable and efficient particle-in-cell method for the massively parallel finite-element code ASPECT. I discuss the complexity of the implemented algorithms, present scaling tests and discuss load-balancing strategies like balanced repartitioning for particles in adaptive meshes with their strengths and weaknesses. Additionally, I will show an application tutorial on how to convert a model with compositional fields into one using the particle advection scheme, and which consequences follow from this conversion for model runtime and accuracy. Connect: http://uc-d.adobeconnect.com/r28i3av93ti/ Vote. The slate of candidates slate of candidate s for two positions on the EC and two positions on the SSC is available. Contact your member representative to vote. Voting closes November 30th. Annual Business Meeting. Please join us and your colleagues at the Annual Business Meeting @AGU on Monday, December 12 @ 6pm at the Intercontinental. The venue (same as last year) is conveniently adjacent to Moscone West. Looking forward to seeing you soon.

Timothy and Deanna Sellnow, Professors in Strategic Communication, Nicholson School of Communications, University of Central Florida Abstract: The demand for effective warning messages and instructions for self-protection is clear in emergency situations. Hazards, such as earthquakes and tsunamis, place entire communities at risk. Warnings and advice for self-protection are essential for personal safety. Although the need is evident, the specific recommendations for message design and distribution of emergency messages are often less clear. This presentation focuses on meeting the need for well-designed messages in emergency situations. Specifically, the presentation summarizes a decade of empirical research, culminating in specific message design and distribution strategies for effective emergency communication. In addition to briefly summarizing recent, relevant research, including several studies focusing on earthquake early warning, the presenters provide a practical message template that can be adapted quickly to fit a variety of emergency situations. At the end of this presentation, geoscience students and professionals should be able to: identify key strategies for tailoring messages to fit the needs of those who are at greatest risk; understand the degree of explanation needed to inform lay audiences without overwhelming their science literacy; develop specific actionable instructions for self-protection; and identify the best communication channels for distributing messages for communities impacted by earthquakes. After registering, you will receive a confirmation email containing information about joining the webinar. NOTE: Registration does not confirm or guarantee you will have a spot during the webinar, as we are limited to 100 participants.

An enduring problem in geoscience is that different scales of heterogeneity typically require different techniques and methods for investigation. Notably, seismology and geodynamics probe scales larger than 10 km, whereas experimental petrology and mineral physics inform about the sub-cm scale. Yet ultimately we wish to combine the results of these investigations to provide a clear and complete picture as to the origin and evolution of mantle heterogeneity at every scale from the surface to the core-mantle boundary. This requires assimilating insights from seismology, geochemistry, mineral physics, and geodynamics to provide an holistic view of the mantle. In this session we bring together Earth scientists interested in the present and past state of the mantle. We aim to facilitate lively and interdisciplinary discussion and provide inspiration for new collaborative studies aimed at elucidating the chemical and dynamic processes operating in the mantle. -------------------- We have solicited talks by Dan Frost (ASU) and Hauke Marquardt (Bayerisches Geoinstitut). Scientists who wish to apply for *financial support* should submit an abstract, on which they are first authors, *by 1 December 2016*.

To accomplish that we invite you to submit an abstract to EGU 2017 session: “TS5.1/SM6.5 Bridging Earthquakes and Tectonics: give-and-take”. Session description: Long-term tectonic processes shape the bulk of conditions under which faults operate and thereby influence earthquake processes on short time scales. In turn, rupture processes locally reduce the strength of the brittle lithosphere and thereby affect the long-term processes that shape our plate boundaries. Reconciling observations of mechanisms taking place across these different time and spatial scales will improve our understanding of the physical processes governing the seismic cycle and the construction of geological and topographic structures, the rheology of the lithosphere-asthenosphere system, and may ultimately improve seismic hazard assessment. Specific questions include how long-term crustal and lithospheric dynamics and structures affect short-term seismicity and earthquake cycle behaviour, and conversely how earthquake cycles result in the construction of geological and topographic features. What are the driving forces and the rheological structure at plate boundaries? What are the relative contributions of rheology (temperature, fluids, chemistry) and geometry in the segmentation of fault ruptures? What are the roles of faulting and off-fault deformation in shaping the landscape and partitioning seismic and aseismic energy dissipation? And what new information can be extracted regarding this from the wealth of geophysical observations in the age of big data? These example questions are intended to stimulate a discussion about the interplay between seismicity, earthquake cycle dynamics and the geological and geodynamic evolution of deforming zones. Therefore we seek contributions from across the fields of geology, geodynamics, seismology, geodesy and geomorphology, encouraging both modelling and observational studies.

Thanks. -Derek -- Derek Schutt, Associate Professor Geosciences Colorado State University 970-491-5786 ---- Dear Colleagues, We are happy to announce the formation of a CIDER working group on the physical state of the mantle lithosphere and asthenosphere. A principal goal is to write a review paper that summarizes what is known about the composition and temperatures of this part of the Earth and to summarize the present state of knowledge on the effects of composition, temperature, pressure, melting, LPO, and other characteristics on observables that include seismic velocities, conductivity, basalt chemistry, and density. We intend to start work on the paper immediately, initially using a Google Doc platform. We plan to meet at AGU from 2:30-3:30 on Wednesday December 14, to discuss further and begin to coordinate tasks. Tentatively we will be at the tables in the right-hand side of the Moscone South poster room, but we will keep interested parties informed if this changes. In spring 2017, we will meet again at Colorado State University in Fort Collins. Our goal is to get the paper finalized by the start of summer (which is when our CIDER minigrant will expire). Please email Derek if you have any questions or wish to express specific or broad interest. We understand that not everyone will be able to make the initial AGU meeting.
