Klein Receives 2012 Atmospheric Sciences Ascent Award

Andrew E. Dessler, Jose L. Jimenez, Stephen A. Klein, and Athanasios Nenes received 2012 Atmospheric Sciences Ascent Awards at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes “research contributions by exceptional mid-career scientists in the fields of atmospheric and climate sciences.”


OThe Atmospheric Sciences section of AGU awards one of the four Ascent Awards to Dr. Stephen Klein of the Lawrence Livermore National Laboratory. The award is made for the substantial contributions Dr. Klein has made toward understanding some of the field’s most important problems, the interaction of clouds and climate through (as noted in his nomination) “the careful analysis of observations, the insightful use of models of varying complexity and his ability to synthesize diverse strands of knowledge.”
He has worked on a broad range of problems, from microphysical processes in mixed-phase Arctic clouds to the role of clouds in ocean-atmosphere interactions. He is described as working “at the important intersection of cloud observations, analysis, and climate model development.” His work is summarized as “doing it all, in a challenging field, successfully bridging across areas of research…in a way no one else in the U.S. can match.” His nominators point toward the enormous influence he has had on advancing the study of clouds and climate, and he is described as “pioneering contributions in every facet of our field, from the development of new ideas, to the building of tools, to the creation of important organizational structures.”
Dr. Klein’s Ascent Award is well deserved and results from his thoughtful and important research into the critical problems associated with the interaction of clouds and climate.

I am honored to receive this recognition. I wish to thank all those who have helped me in my career, including those from where I received my education as well as those I have encountered at the different positions I have held. I have been very fortunate in interacting with many great people.

—STEPHEN A. KLEIN, Lawrence Livermore National Laboratory, Livermore, Calif.

Jimenez Receives 2012 Atmospheric Sciences Ascent Award

Andrew E. Dessler, Jose L. Jimenez, Stephen A. Klein, and Athanasios Nenes received 2012 Atmospheric Sciences Ascent Awards at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes “research contributions by exceptional mid-career scientists in the fields of atmospheric and climate sciences.”


JimenezThe Atmospheric Sciences section of AGU awards one of the four Ascent Awards to Professor Jose-Luis Jimenez of the Department of Chemistry and Biochemistry at the University of Colorado Boulder. The award is made for the development and utilization of innovative measurement technology to address critical aspects relating to the sources, transformations, and environmental fates of fine atmospheric particles.

The letters of nomination note the prolific and highly cited publication record of Professor Jimenez and his group that is almost unprecedented for a mid-career scientist. It was also highlighted that he has played a leading role in a large number of field experiments. Perhaps Professor Jimenez’s career can be summarized best by the following statement from his nomination letter: “Professor Jimenez is without question a brilliant and productive atmospheric scientist, a wonderful mentor, and a leader in his field.”

Professor Jimenez is well worthy of an Ascent Award through thoughtful and important research that has been disseminated broadly in the literature and is having a major impact on the atmospheric sciences.

—PETER J. WEBSTER, Georgia Institute of Technology, Atlanta


I am honored and humbled to receive the 2012 Ascent Award from AGU. Not so long ago, I remember being amazed by the energy, excitement, and rigor that I witnessed at my first AGU Fall Meeting in 1999. I have been lucky to participate in a period of rapid learning about the composition and sources of aerosols at a time when science is increasingly collaborative. There is still much to be learned in this and related fields to have confidence in our predictions of climate forcing and air quality, and I look forward to many more collaborations and AGU Fall Meetings during the second half of my career.

There are many people I would like to thank. I have had excellent mentors during my career, but I owe special thanks to Doug Worsnop for his unrelenting support and for being a truly inspiring role model, always ready to answer any question or be challenged into an interesting discussion. The many talented members of my research group, past and present, have made research invigorating and taught me how to be a better mentor. The Aerodyne mass spectrometer communities have been an example of cooperation and a constant source of interesting ideas and discussions. I have been fortunate to collaborate widely across our community, including several intense field studies, and I am grateful to the many researchers I have worked with in the process. And, of course, none of this would have been possible without the support and encouragement of my wife, Yumi; my family; and my good friends. I dedicate this award to them.

—JOSE L. JIMENEZ, University of Colorado Boulder

Dessler Receives 2012 Atmospheric Sciences Ascent Award

Andrew E. Dessler, Jose L. Jimenez, Stephen A. Klein, and Athanasios Nenes received 2012 Atmospheric Sciences Ascent Awards at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes “research contributions by exceptional mid-career scientists in the fields of atmospheric and climate sciences.”


DesslerThe Atmospheric Sciences section of AGU awards one of the four Ascent Awards to Professor Andrew E. Dessler of the Department of Atmospheric Sciences at Texas A&M University for fundamental contributions to the understanding of stratospheric-tropospheric exchange processes and the physics of ozone depletion and for attempts to unravel water vapor and cloud feedbacks in the climate system. In addition, he is commended for his ceaseless work in communicating the science of climate change to the public.

His letters of recommendation speak to his work and “path breaking” and imparting of a “major impact on science and on dissemination.” His work on climate feedbacks is described as “pioneering,” and his accomplishments “have enhanced our understanding and assessment of the intricate play among water vapor, clouds, and surface temperature increase in the Earth’s atmosphere.”

Andrew E. Dessler is well worthy of an Ascent Award and personifies exceptional scientific accomplishments in a field of difficult but important science.

—PETER J. WEBSTER, Georgia Institute of Technology, Atlanta


I’d like to thank the Atmospheric Sciences Section Award Committee for this recognition.

I’d like to say that I’m humbled to join the illustrious group of former winners, but because this is the first time the award has been given, I leave that platitude for next year’s winners. Most of all, I’d like to acknowledge the entire climate science community. Over the last several decades, thousands of us have devoted our professional lives to studying climate, and the community has done a remarkable job of working out the physics of the problem. Ignored by many, demonized by some, I believe that future generations will look back and say, “They nailed it.” It has been an honor to work with all of you on this problem.

—ANDREW E. DESSLER, Department of Atmospheric Sciences, Texas A&M University, College Station

Nenes Receives 2012 Atmospheric Sciences Ascent Award

Andrew E. Dessler, Jose L. Jimenez, Stephen A. Klein, and Athanasios Nenes received 2012 Atmospheric Sciences Ascent Awards at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes “research contributions by exceptional mid-career scientists in the fields of atmospheric and climate sciences.”


NenesThe Atmospheric Sciences section of AGU awards one of the four Ascent Awards to Professor Athanasios Nenes, of the School of Earth and Atmospheric Sciences and School of Chemical and Biomolecular Engineering of the Georgia Institute of Technology, for the creation of thermodynamical models for tropospheric aerosols and the development of physically based ­aerosol-­cloud parameterizations. In addition, he is recognized for the design of instrumentation and techniques to characterize the hygroscopicity and activation of cloud condensation nuclei (CCN) and also for contributions to the understanding of the role of aerosols in climate and air quality.
His nomination letters speak of the enormous contribution he has made over a wide range of fields. For example, “each of these contributions [referring to the Nenes’ instrumentation development] has reshaped the landscape of how one measures and interprets CCN data…. I know of no other individual who is equally adept across theory, instrument development, and laboratory and field measurement.” Another nominator notes, “the amazing thing about Thanos is that he has served as a one-stop-shop, end-to-end source of information into aerosol processes and cloud-aerosol interactions, from the laboratory to the field to theory to parameterizations” and “his scholarly work…both experimental and theoretical, is without peer at any age.”
Professor Nenes is abundantly qualified to receive an Ascent Award through his major contributions to many areas of aerosol research.

—PETER J. WEBSTER, Georgia Institute of Technology, Atlanta


It is a rare privilege and a deeply fulfilling experience to pursue science while helping shape future generations of scientists and engineers. To be awarded on top of it is humbling to say the least. I am deeply grateful to my nominator and supporters and thank the AGU Atmospheric Sciences Section Awards Committee for this honor. What makes the Ascent Award even more special is its strong vote of confidence for the future, which is both energizing and inspiring.
I have many people to thank: first and foremost, my wife, Luz. Her love, patience, understanding, and continuous support are a source of inspiration that has only strengthened since the birth of our two lovely children, Hector Angelos and Esperanza Dafni. I also thank the Georgia Institute of Technology and my chairs, Glenn Cass, Judith Curry, Ronald Rousseau, and William Chameides, for providing the opportunity to start a research program and doing everything possible to help it flourish. I thank my colleagues Mike Bergin, L. Greg Huey, and Rodney Weber for generously sharing their expertise and resources all these years. My deepest gratitude goes to present and past members of my research group; your inexhaustible enthusiasm, motivation, creativity, and hard work have accomplished more than I could have ever imagined.
I am forever grateful to my Ph.D. advisor John Seinfeld, Spyros Pandis, Richard Flagan, and my M.Sc. advisor Christodoulos Pilinis. They introduced me to aerosol science, shaped me as a scientist, and provided continuous guidance, support, friendship, and opportunity for collaboration. I am also grateful to Greg Roberts for an amazing collaboration on CCN instrumentation and to Greg Kok, of Droplet Measurement Technologies, for enabling its commercial success.
Finally, I dedicate this award to my parents, Theodosio and Maria. By example, they taught me to aim high, work hard for it, and never give up trying.

Bhartia Receives 2012 Yoram J. Kaufman Unselfish Cooperation in Research Award

Pawan K. Bhartia received the Yoram J. Kaufman Unselfish Cooperation in Research Award at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes “broad influence in atmospheric science through exceptional creativity, inspiration of younger scientists, mentoring, international collaborations, and unselfish cooperation in research.”


BhartiaDr. Pawan K. Bhartia, the winner of the Kaufman award, is a senior research scientist in the Atmospheric Chemistry and Dynamics Branch at NASA Goddard Space Flight Center in Greenbelt, Maryland.

His accomplishments can best be described by quoting from his nomination letters. “How does one think about P. K. without thinking about Yoram? P. K. embodies Yoram’s spirit of pure joy of research and exuberance in sharing this joy with just about everybody. True, P. K. is quieter than Yoram and seemingly more reserved, but his enthusiasm for scientific inquiry and the mentoring of young scientists is equally unbounded. Bhartia[’s] unwavering goal is to advance the science that can be obtained from remote sensing data. In his pursuit of this goal, P. K. knows no barrier, no international boundary, no language impediment, no age divisions. There is only the advancement of the science. To advance this goal, he has inspired and cultivated the next generation of remote sensing scientists in the U.S., and was a leader in the negotiations to fly the Dutch Ozone Monitoring Instrument (OMI) on the NASA Aura spacecraft. There is no one in the business less selfish, more cooperative and self-­effacing than P. K. His last first-­author paper was in 1996, preferring since then to let younger scientists have the opportunity to take the lead. He appears as coauthor on more than 90 papers, and you can be sure that he made substantial contribution[s] in each one, because P. K. turns down ‘ceremonial’ offers of coauthorship right and left.” [Quotation from a letter signed by 27 “scientists, young and old, who are proud to call P. K. Bhatia their mentor, guide and/or inspiration.”]

“It is very rewarding to work with him, because of his excellent ideas, his inspiration and his unselfishness, the latter being a rare quality amongst sci-entists.” “…P. K. has been a prolific source of ideas for the development, improvement, and extension of the ozone retrieval algorithms used in the operational ozone satellite program. His guidance and vision in algorithm development, measurement calibration, and product validation are directly re-sponsible for the success of the NOAA Solar program’s operational near-real-time ozone products and ozone climate data records…. He is happiest when he has been able to provide useful direction to the research paths of his colleagues. His modest assessment of his own ideas and openness to novel ideas makes it easier for others to explore new areas as well as allowing them to admit the inefficiencies of their current approaches. He is an excellent sounding board with a strong ability to find the key underlying questions or assumptions that must be addressed to move research forward. A proper accounting, usually hidden in an acknowledgment of the contributions of the NASA Ozone Processing Team (P. K. has been the guiding light of this team for the last 30 years), would show that the majority of my publications drew important content from his suggestions despite his less frequent appearance as a coauthor. His genuine desire to understand the methods and messages of every presentation he attends matched with his respect for good science and creative solutions create a level playing field where new and old team members’ contributions are nurtured and sifted to produce the best results.”

“I have always found P. K. to be an exceedingly likeable person, one who plays down his own manifold accomplishments. In personal interactions, he is always interested in what other people have to say, and encouraging of their ideas and goals. Dr. Bhartia has worked tirelessly and selflessly over the decades to ensure that new and valuable atmospheric observations be made available to the scientific community, and to ensure that a new generation of atmospheric scientists are well placed to exploit these observations for decades to come. Dr. Bhartia’s selfless dedication to the field, to nurturing his colleagues, and to collaboration with other scientists, make him truly deserving of this award.”

For these reasons, the AGU Atmospheric Sciences Section is proud to award the 2012 Kaufman Award to P. K. Bhartia.

It was an honor and pleasure to receive the 2012 Yoram J. Kaufman Unselfish Cooperation in Research Award from the Atmospheric Sciences Section of the American Geophysical Union. Yoram and I joined NASA around the same time and were colleagues at NASA Goddard Space Flight Center until his tragic death in 2006 in a bicycle accident inside the GSFC campus. The award named after him not only honors Yoram’s life and work, but it is also one of the rare scientific awards given for collaboration and teamwork, in which Yoram excelled.

As the complexity of scientific research is increasing, scientific progress increasingly requires team building, mentoring, and cooperation. This is particularly true of the science we do at NASA. Though I have received many personal career achievement awards from NASA and other organizations, I cherish the team awards most.

Most of all, I cherish the citation and the nomination letters sent by some 27 of my colleagues for this award. I didn’t know that I had touched the lives of so many. My greatest reward has been the pleasure to work with them. I think the famous Chinese proverb doesn’t quite capture it. The pleasure one derives from teaching someone how to fish is at least as important as the skill one conveys.

Tsai Receives 2012 Keiiti Aki Young Scientist Award

Victor C. Tsai received the 2012 Keiiti Aki Young Scientist Award at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes the scientific accomplishments of a young scientist who makes outstanding contributions to the advancement of seismology.


Tsai Victor Tsai is the well-deserved winner of the 2012 Keiiti Aki Young Scientist Award. He received his bachelor’s degree from the California Institute of Technology, then went to Harvard for graduate school, where he received his Ph.D. in 2009. He did a Mendenhall postdoc at the U.S. Geological Survey in Golden, Colo., for 2 years, then returned to Caltech as an assistant professor last year. Victor has worked on an incredible range of topics, including the 2004 and 2012 Sumatra earthquakes, glacial earthquakes and more general problems of glacier physics, microseism generation and ambient noise cross-correlation theory, river turbulence, and tsunami modeling. All of his research is elegant and theoretically rigorous. Victor has 26 papers to date, including 7 this year alone. He already has a substantial body of work, which promises an outstanding career.

PETER M. SHEARER, Scripps Institution of Oceanography, University of California, San Diego, La Jolla


I am honored to receive the Aki Award, but I would not be receiving this award without the benefit of many collaborations and inspirations as well as extensive mentoring and infrastructural, personal, and financial support. Although there are more individuals to thank than can be listed here, special thanks are due to Jim Rice, Hiroo Kanamori, Dave Stevenson, and Göran Ekström, who have all been irreplaceable mentors. I am also indebted to many other teachers, colleagues, and friends and to my parents, who have inspired in me a curiosity about the world, taught me the importance of hard work and persistence, supported my endeavors, and provided unimaginably rich opportunities throughout my life.

I especially appreciate this recognition by the AGU Seismology section because I would not call myself a traditional seismologist. My interests have often been on the fringes of seismology, including some topics that are not seismological and others that will likely never be more than a curiosity. Yet it is difficult to predict what will be useful many years later, and I feel fortunate to have been encouraged to follow some of my crazy ideas. While a number of these ideas have led nowhere, some of my least conventional and least cited efforts are ones that I am most proud of. Perhaps not surprisingly, I have also found a correlation between the difficulty my papers have had in peer review and how exciting I thought the results were.

All this is to say that I hope tomorrow’s young scientists will have similar opportunities and that they have the courage to explore their own interesting ideas. I hope that they will be allowed to take risks, continue to explore curiosity-driven science, and be able to think about problems that are not fashionable or challenge the current scientific consensus.

Nyblade Receives 2012 Paul G. Silver Award for Outstanding Scientific Service

Andrew Nyblade received the Paul G. Silver Award for Outstanding Scientific Service at the 2012 AGU Fall Meeting, held 3–7 December in San Francisco, Calif. The award recognizes outstanding contributions to the fields of geodesy, seismology, or tectonophysics through mentoring of junior colleagues, leadership of community research initiatives, or other forms of unselfish collaboration in research.


NybladeAndrew Nyblade is the first recipient of AGU’s new Paul G. Silver Award for Outstanding Scientific Service. This award is given jointly by the Seismology, Geodesy, and Tectonophysics sections to a section member who has made outstanding contributions to these fields through mentoring of junior colleagues, leadership of community research initiatives, or other forms of unselfish collaboration in research. The award was named for the late Paul Silver as a tribute to the excellence and generosity of his scientific service and the importance of his research on mantle anisotropy, continental evolution, subduction zone dynamics, and earthquake source processes.

Andy Nyblade received a bachelor’s degree from Wittenberg University in Ohio and his Ph.D. in 1992 from the University of Michigan. He then did a postdoc at Penn State, where he has largely been ever since, becoming a full professor in 2007. Andy is a first-rate scientist who has specialized in seismic and other geophysical investigations of the African continent, which have highlighted the unique dynamical and thermal properties of the African mantle. His service contributions have been truly exceptional, in particular his development and leadership of the AfricaArray project, which has established key programs to improve African geophysics education and instrumentation.

Working in collaboration with African scientists, AfricaArray has installed a number of seismic stations across Africa, while training young African seismologists in order to build an in-house capability to collect, analyze, and interpret the data, which of course are also freely available to scientists around the world. The goal is not simply to collect African data and leave but to build local institutions, infrastructure, and expertise. The program has now expanded to include geodesy and other fields.

The success of this project required Andy’s vision and drive, his ability to build and sustain relationships, and his perseverance in obtaining funding from a variety of sources. He has supervised and mentored many African students who have come to Penn State. In addition, Andy has worked to improve geoscience training for students in U.S. minority-serving institutions, including historically black colleges and Hispanic-serving universities in Texas and California. He has served as an outstanding research advisor and mentor to numerous younger scientists, many of whom have gone on to faculty positions themselves. Overall, Andy Nyblade has compiled an outstanding record of service, including unique contributions to educating underserved populations in both Africa and the United States, as well as obtaining new data sets and important new research results.

PETER M. SHEARER, Scripps Institution of Oceanography, La Jolla, Calif.


I would like to thank Peter Shearer for his citation and the Seismology, Geodesy, and Tectonophysics sections for this honor. Paul Silver was a friend and mentor, and so receiving this award is especially meaningful. I first met Paul in 1993 when I was a postdoc writing a National Science Foundation proposal to deploy a seismic network in Tanzania and recall his strong encouragement to not cut back on the size of the project in spite of the cost. The project, which was funded, helped pave the way for the development of AfricaArray more than a decade later, illustrating Paul’s far-reaching influence on the community through his support of junior scientists.

While I am receiving this award in large part because of the achievements of the AfricaArray initiative, those achievements are not mine alone but reflect the dedication and efforts of many scientists; their willingness to share research infrastructure, data, and training courses; and their commitment to improving geoscience education in Africa. In 2004, when Paul Dirks, then head of the School of Geosciences at the University of the Witwatersrand in Johannesburg, South Africa, and I developed the plan for AfricaArray, it was abundantly clear that we needed to address the underrepresentation of students from disadvantaged communities in South Africa. We soon realized that extending a focus on diversity to other African countries, as well as to the United States, would serve to further strengthen AfricaArray, and thus, a multinational diversity program was made a cornerstone of the initiative, along with a pan-African seismic network and a training program for African postdocs and students.

I would like to thank all of the many AfricaArray partners, faculty, postdocs, students, and sponsors and, in particular, Paul Dirks, Ray Durrheim, Roger Gibson, and Sue Webb (University of the Witwatersrand) and Gerhard Graham (Council for Geoscience, South Africa) for their important contributions to building AfricaArray.

Haq Receives 2004 Ocean Sciences Award

Bilal Haq of the U.S. National Science Foundation received the Ocean Sciences Award at the awards program on 28 January in Portland, Oregon, for “extraordinary contributions and service” to ocean sciences.


haq_balil“Bilal Haq’s extraordinary contributions to ocean sciences will certainly have a long-lasting impact in the continuing development of our knowledge in marine geosciences. It is our pleasure to offer this brief citation of Bil’s very long list of accomplishments for a well-deserved award in ocean sciences by the American Geophysical Union.

“For nearly sixteen years, Bil Haq has selflessly served the ocean science community in his capacity as the director for marine geosciences programs at the National Science Foundation showing distinctive leadership in initiating and promoting significant new initiatives important to the continued vitality of marine geosciences.

“Bil received his doctorate degree from the University of Stockholm in Sweden and went on to pursue an extremely productive research career at Woods Hole Oceanographic Institution, before joining Exxon Research Labs in Houston for an equally productive career in the industry. During that time, he worked and published extensively on a variety of issues related to soft-rock geology; Bil was a true pioneer in the fields of paleobiogeography, paleoceanography, sequence stratigraphy, and eustasy. Some of his publications are among the most highly cited papers in Earth sciences. In 1988, he joined NSF and has had a distinctive career as the director for marine geology and geophysics programs. His impact on sedimentary geology has been widely recognized; in 1998, he was awarded the Francis Shepard Medal by the Society for Sedimentary Geology (SEPM); and in 1999, he was elected fellow by the American Association for the Advancement of Science. Bil also received the NSF’s Antarctic Service Medal in the same year. Bil Haq is most remarkable and somewhat unique in continuing to publish research papers despite his busy duties as the director of one of the major programs at NSF.

“During his tenure at NSF, Bil has been a most proactive program director, not just responding to the community’s wishes, but proactively soliciting their views and, when needed, nudging them in the right direction. Several examples of initiatives he has begun or vigorously advanced are Marine aspects of Earth System History (or MESH) which is a Global Change initiative, and the MARGINS Program. Over the years, he has also prodded the sedimentary geology community to become more quantitative and to test their concepts through modeling. Bil has also actively encouraged gas-hydrate research by increasing the awareness of its importance both inside and outside NSF since 1990 through publications, talks, and an appearance before a Congressional Committee to support such research. His proactive stance towards marine geoscience research is further exemplified by the ‘Future of Marine Geosciences’ workshop that he organized with his MG&G colleagues in 1996 in order to actively involve the community in the planning for the future of their science. The results of the workshop (also called the FUMAGES Report) will guide future directions in marine geosciences for years to come.

“Bil has also been very effective in promoting marine geosciences internationally, by helping several burgeoning oceanographic institutions in developing countries with initial planning and identifying future directions, and by participating in UNESCO’s Inter-governmental Oceanographic Commission and IUGS committees and panels. His assignment with the World Bank during 1996 was also focused on helping ocean science research and development and integrated coastal zone management in developing countries.

“Bilal Haq richly deserves the Ocean Sciences Award for his long-standing and dedicated leadership and services in marine geosciences, and his extraordinary contributions to ocean sciences in the fields of paleoceanography, marine stratigraphy, eustatic sea-level changes, and sedimentary geology.”

Florentin Maurrasse, Florida International University, Miami
James P. Kennett, Institute of Marine Sciences, University of California, Santa Barbara


“Thank you, Florentin and Jim for your kind words and to AGU’s Ocean Sciences Section for this honor. It is especially nice to be recognized for simply doing your job, particularly when you are fortunate enough to be happily immersed in an environment where countless bright ideas are continuously proposed all around you. How could anyone ask for a better job? You don’t have to write proposals, struggle constantly to raise your salary, fight with the dean to keep your space or with the chairman to keep your tech, and yet you are in the midst of some of the most exciting science in your field. Working at NSF for me has been a bit like being a referee or even a ball thrower at Wimbledon.

“I would be remiss if I did not acknowledge all the wonderful help I have received in performance of my duties from colleagues in the Division of Ocean Sciences as well as other divisions at NSF, especially my fellow program officer and friend Dave Epp and too many talented rotating scientists from the community to mention by name. You might say that my management style at NSF has, by choice, been what one might call of the ‘matrix’ type (as opposed to a ‘pyramidal’ kind). This approach seems to have attracted truly accomplished scientists from the community to come work with us, who have visibly enhanced the MG&G Program and our rapport with the community that we serve. I hope we can keep attracting talented new blood to our visiting scientists’ program that is so vital for NSF to remain current. Matrix management allows you to share the burden as well as decision-making authority within the group and it encourages greater horizontal communication. One fine by-product of such lateral shared responsibility is that it affords you an occasional pause in which to pursue your own research and, thanks to NSF, I have been lucky to be able to follow some of my own research ideas over the years. Alas, I just don’t seem to be able to divest myself of the research bug!

“In parting, I hope you will indulge me by allowing me to mention a concern of mine. In recent years, I have been a bit worried about our complacency as research scientists. We may not be paying enough attention to the immediate relevance of our work to society, remaining quite content if only a handful of our colleagues understand or care about what we accomplish. I believe that we have to change this mind-set if we want to claim greater impact in solving pressing societal problems of resource exploitation and conservation, environmental degradation and remediation, and the overall quality of human existence, problems that loom big in this century. As stewards of the oceanic milieu, we will be called upon to provide lasting solutions and must prepare ourselves to face these issues.

Schauble Receives 2009 Hisashi Kuno Award

Edwin A. Schauble received the Hisashi Kuno Award at the 2009 AGU Fall Meeting, held 14–18 December in San Francisco, Calif. The award is for outstanding contributions to the fields of volcanology, geochemistry, or petrology.


schauble_edwinIt is my pleasure to present Edwin Schauble for the Hisashi Kuno Award of the AGU Volcanology, Geochemistry, and Petrology (VGP) section, for his outstanding contributions to the field of geochemistry.

Edwin is a young scientist of uncommon distinction who has made a number of important contributions through his quantitative approach to stable isotope geochemistry.

Let me start by saying that when Edwin came to University of California, Los Angeles (UCLA), I learned two things. First, physics really does operate in predictable ways, even where isotopes are concerned, and second, disagreeing with Edwin is usually a lesson in humility!

Edwin’s primary research entails calculating the partitioning of isotopes between materials of geological interest. In particular, he has produced pioneering predictions of partitioning among the so-called nontraditional stable isotopes. He has also followed through by testing his predictions experimentally. To date, Edwin has published important predictions for fractionation of Mg, Si, Ca, Cl, Fe, Cr, Hg, Tl, and U isotopes in a broad spectrum of minerals and fluid species.

In summary, Edwin is at the forefront of isotope geochemistry and can already claim several important discoveries to his credit, including, but not limited to, elucidation of the relative importance of valence state and coordination on iron isotope fractionation in nature, a large fractionation in Si isotopes that should exist between the metallic cores and rocky mantles of terrestrial planets, the quantification of mass-independent nuclear volume isotope effects in U and other elements, numerous predictions of mass-dependent nontraditional stable isotope fractionation with surprising accuracy, and development of the theory behind stable isotope “clumping.” This work has had a substantial impact on activities as disparate as reconstructing past climates and differentiation of terrestrial planets. His work is paving the way for new branches of geochemistry, and he is uniformly highly regarded by colleagues around the globe. For all of these reasons, I am sure you will agree that Edwin is most deserving of this prestigious award.

Edward Young, University of California, Los Angeles


Thanks for the kind introduction, and thanks to the VGP section of AGU. This award honors work done at the beginning of a career, and most of that honor should go to everyone who helped me make a good start. That list begins with my colleagues at UCLA: Ed Young, Abby Kavner, and Craig Manning, my students Jon Hunt and Pam Hill, postdoc Merlin Méheut, and many others. Sometime between junior high school and tenure, school got really fun, and all of you are the reason. I mostly try to figure out how isotopes get separated from each other—fractionated—in nature. We are in a golden age for this kind of work; talented researchers are developing new techniques to analyze isotopic compositions of one element after another, finding signatures that might help answer big questions in Earth and planetary science.

I want to thank George Rossman and Liz Johnson for helping me learn to model isotope fractionation, and Ariel Anbar and John Eiler for encouraging me to refine my initial, fairly crude results into a paper. I also want to thank John for a totally killer postdoc. My initial interest in metal isotope geochemistry owes much to Joe Kirschvink. Scientific chats with Joe tend to be about big ideas that sound crazy or impossible (think “panspermia”) but are backed up by an array of evidence (think “Snowball Earth”), and are at least occasionally true. These are still important criteria to me in finding problems to work on. I want to thank Hugh Taylor, my Ph.D. advisor, for the freedom to try something different and uncertain, and Steve Wickham, my undergraduate advisor, for introducing me to isotopes, mass spectrometers, and the satisfaction of making new measurements. Finally, I want to thank my parents, Carolyn and John Schauble, for teaching me that knowledge and love are the two things most worth adding to the world.

Rust Receives 2010 Hisashi Kuno Award

Josef Dufek and Alison Rust each received the Hisashi Kuno Award at the 2010 AGU Fall Meeting, held 13–17 December in San Francisco, Calif. The award recognizes “accomplishments of junior scientists who make outstanding contributions to the fields of volcanology, geochemistry, and petrology.”


rust_alisonAlison Rust is an igneous petrologist and physical volcanologist whose work has addressed some of the most basic processes that govern the generation, ascent, and eruption of magma. This includes the rheology of bubbly magma; how to determine deformation rate and history of magmas using microstructures; measurements and models of the permeability of pumice; degassing of magma and, in particular, the coupled degassing and brecciation of magmas; convection in magmas that have a yield strength; and the generation of seismic waves by flow through channels and conduits.

This range of topics is remarkable. More impressive, however, is the broad range of approaches she uses to answer these fundamental volcanological questions: lab experiments, analytical geochemistry, fieldwork, numerical modeling, and developing theoretical models. Especially noteworthy is her clever and insightful use of analog experiments to make the key link between observations and theory.

Moving beyond incremental advances in igneous petrology often requires quantitative integration of observations, experiments, and models coupled with a healthy dose of creativity and a willingness to question standard ideas. These are attributes Alison has demonstrated with her past work, and we look forward to more in the future.

It is an honor and a pleasure to receive the Kuno Award. There are, of course, so many people who deserve thanks, but I am especially indebted to my four enthusiastic advisors while I was a graduate student and postdoc: Kelly Russell, Michael Manga, Kathy Cashman, and Neil Balmforth. They were all very supportive but also gave me the space and freedom to make my own mistakes. I would like to thank Kelly for his contagious enthusiasm; Michael for his pithy, wise words; Kathy for bouncing ideas off everything; and Neil for teaching me things I didn’t know I wanted to know.

I have landed at the University of Bristol, which is a remarkable environment in which to continue to develop as a researcher, although sometimes it’s hard to get any work done with all the interesting discussions (thanks, Luca). I hope I can continue to find enjoyable collaborations and generate quality research worthy of the expectations of an early-career award.
