Geology & Geophysics News GEOLOGY & GEOPHYSICS NEWS Yale University I Department of Geology and Geophysics Winter 2008 Chairman’s Letter Interior Renovations to the Kline Geology Lab David Bercovici Greetings, friends of Yale Geology & Geophysics, this is my second year as Chair of our fine department, and it gives me great pleasure to tell you about the many events of the last year. There have been numerous changes, including new faculty, new graduates, expansion in numbers of undergraduate majors, graduate students, and postdoctoral scholars; even the building has seen renovations. Early in 2007 we ran two simultaneous junior searches, one in mineral physics and geophysics, the other in isotope geochemistry. The searches led to the appointment of four new faculty, two in each of the disciplines. The new assistant professors The results of renovations—the auditorium looking toward the podium, and the departmental lounge. are geochemists Hagit Affek and Zhengrong Wang, both of whom started in July 2007, and geophysicists Kanani Lee (who starts in July 2008) and Maureen Long (who starts in January 2009). Each brings unique talents to the Department, and they will oversee major expansions in isotope geochemistry, mineral physics and seismological research. You can find profiles and a photo of each of them later in this newsletter. As we add new young faculty, our formerly young faculty are getting older and this year saw the promotions of geophysicist Jun Korenaga to Associate Professor, and atmospheric physicist Steven Sherwood to Professor. You might recall that Jun Korenaga was the recipient of the James B. Macelwane Medal from the American Geophysical Union in 2006, and Steve Sherwood received the Clarence Leroy Meisinger award from the American Meteorological Society in 2005.

  • Effects of Water on Seismic Wave Velocities in the Upper Mantle Terior. Therefore, If One Understands the Relation Between Water
    No. 2] Proc. Japan Acad., 71, Ser. B (1995) 61 Effects of Water on Seismic Wave Velocities in the Upper Mantle By Shun-ichiro KARATO Department of Geology and Geophysics, University of Minnesota, Minneapolis, MN 55455 (Communicated by Yoshibumi ToMODA,M. J. A., Feb. 13, 1995) Abstract : Possible roles of water to affect seismic wave velocities in the upper mantle of the Earth are examined based on mineral physics observations. Three mechanisms are considered: (i) direct effects through the change in bond strength due to the presence of water, (ii) effects due to the enhanced anelastic relaxation and (iii) effects due to the change in preferred orientation of minerals. It is concluded that the first direct mechanism yields negligibly small effects for a reasonable range of water content in the upper mantle, but the latter two indirect effects involving the motion of crystalline defects can be significant. The enhanced anelastic relaxation will significantly (several %) reduce the seismic wave velocities. Based on the laboratory observations on dislocation mobility in olivine, a possible change in the dominant slip direction in olivine from [100] to [001] and a resultant change in seismic anisotropy is suggested at high water fugacities. Changes in seismic wave velocities due to water will be important, particularly in the wedge mantle above subducting oceanic lithosphere where water content is likely to be large. Key words : Water; seismic wave velocity; upper mantle; anelasticity; seismic anisotropy. Introduction. Water plays important roles in the terior. Therefore, if one understands the relation melting processes and hence resultant chemical evolu- between water content and seismic wave velocities, tion of the solid Earth.

Washington, DC 20015, USA Institute,forGeophysics and Planetary Physics, Scripps Institution of Oceanography, La Jollu, CA 92093-0225, USA Accepted 1997 June 27. Received 1997 June 12; in original form 1997 January 21 SUMMARY Palaeodirectional data from lava flows and marine sediments provide information about the long-term structure and variability in the geomagnetic field. We present a detailed analysis of the internal consistency and reliability of global compilations of sediment and lava-flow data. Time-averaged field models are constructed for normal and reverse polarity periods for the past 5 Ma, using the combined data sets. Non- zonal models are required to satisfy the lava-flow data, but not those from sediments alone. This is in part because the sediment data are much noisier than those from lavas, but is also a consequence of the site distributions and the way that inclination data sample the geomagnetic field generated in the Earth’s core. Different average field configurations for normal and reverse polarity periods are consistent with the palaeo- magnetic directions; however, the differences are insignificant relative to the uncertainty in the average field models. Thus previous inferences of non-antipodal normal and reverse polarity field geometries will need to be re-examined using recently collected high-quality palaeomagnetic data. Our new models indicate that current global sediment and lava-flow data sets combined do not permit the unambiguous detection of northern hemisphere flux lobes in the 0-5 Ma time-averaged field, highlighting the need for the collection of additional high-latitude palaeomagnetic data.

DON LYNN ANDERSON March 5, 1933–December 2, 2014 Elected to the NAS, 1982 Don L. Anderson, the Eleanor and John R. McMillan Professor of Geophysics at the California Institute of Tech- nology, was a geophysicist who made numerous seminal contributions to our understanding of Earth’s origin, composition, structure and evolution. He pioneered applications of seismic anisotropy for global surface waves, contributed to discovering the seismic velocity discontinuities in the mantle’s transition zone and initi- ated their mineralogical interpretation, established deep insights into seismic attenuation, co-authored the most widely used reference Earth structure model, helped to establish the field of global tomography, and re-opened inquiry into the nature of hotspot volcanism and mantle stratification. He contributed to initiatives that upgraded By Thorne Lay global and regional seismic instrumentation. He served as Director of the Caltech Seismological Laboratory for 22 years, overseeing a prolific scientific environment, distilling many advances into his masterpiece book Theory of the Earth. His enthusiasm for debate and his phenomenal editorial efforts raised the scientific standard of students and colleagues alike. Don was a geophysicist of tremendous breadth, publishing about 325 peer-reviewed research papers between 1958 and 2014 in seismology, mineral physics, planetary science, tectonophysics, petrology and geochemistry. He had a remarkable familiarity with the literature across all these disciplines, keeping reprints sorted into a multitude of three-ring binders that he could access in an instant, uniquely positioning him to undertake the writing of his ambitious book, The Theory of the Earth, published in 1989.

    Geophysical Research Abstracts Vol. 12, EGU2010-1362, 2010 EGU General Assembly 2010 © Author(s) 2009 Reconciling Seismology and Mineral Physics in the Mantle Brian L. N. Kennett Australian National University, Research School of Earth Sciences, Canberra ACT, Australia ([email protected], 61 2 62572737) The Earth is a complex 3-D mineral assemblage whose gradients are dominantly with depth. As a result much effort has been expended on trying to tie estimates of mineral properties at depth to indirect inferences about radial structure, e.g., from Seismology. At the scale of sampling of seismic waves most of the mantle appears isotropic, but the constituent minerals are not. There are therefore two issues to be resolved when making comparisons between information derived from equations of state and seismology: firstly, the quality of the estimators for individual minerals and secondly, the way that these mineral specific estimates are combined. The standard procedures work quite well, but if we are to be able to pin down effects such as those due to spin transition in iron atoms we need to improve the representations. In particular it is highly desirable that determinations of equations of state include information at the highest pressures (e.g., shock wave or ab initio) so that any estimate of properties is based on interpolants, rather than extrapolation from the pressure range of regular experiment. It is likely that most current estimates of seismic wavespeed variability in the mantle represent underestimates, yet such variability lies well outside the range of applicability of derivatives from a single adiabat, if indeed this is a suitable reference.
