In Memoriam

Don L. Anderson, president of AGU from 1988–1990, passed away 2 December. Anderson, an AGU Fellow, joined AGU in 1958 and was a member of the Seismology section. He earned his doctorate in geophysics/mathematics from the California Institute of Technology (Caltech) in 1962. A recipient of the AGU Macelwane Medal in 1966 and the Bowie Medal in 1991, he served as Caltech's Eleanor and John R. McMillan Professor of Geophysics. He was 81.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Response

Thank you very much, Jay, for your generous citation and for all of your support. It is a great honor for me to receive this medal. First, I sincerely thank AGU for this recognition and my nominators for their support and time.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Response

Thank you, Niki, for this very kind citation. Not only are you generous in your support, you are also an outstanding and inspiring scientist as well as a great colleague at ETH Zurich. I would also like to thank all those who supported my nomination and AGU's Macelwane committee for choosing me for this great honor. This means a lot to me: The first scientific conference I ever attended was organized by AGU and gave me a lasting motivation to work in science.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Citation for Motohiko Murakami

The James B. Macelwane Medal of AGU is presented to Motohiko Murakami for his discovery of the postperovskite phase of MgSiO3, for a new class of sound velocity measurements under lower mantle pressure‐temperature conditions that have changed our view of whole‐Earth chemistry, and for other fundamental contributions that have furthered our understanding of the Earth's deep interior.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Citation for Jesse H. Kroll

Jesse Kroll is playing a leading role in unraveling the extremely complex multiphase atmospheric chemistry of organic molecules emitted by both anthropogenic activities and biogenic processes. His work is particularly important because atmospheric organic species form a large fraction of airborne submicron particulate matter (PM), which is responsible for most of the adverse human health effects, including premature mortality, attributed to poor air quality. Submicron aerosol PM also drives important direct and indirect impacts on atmospheric radiative transfer, causing much of the uncertainty in our understanding of current, and predictions of future, climate change.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Response

Thanks, Chuck, for the kind words and for the nomination, and thanks to AGU for this great honor. I consider myself extremely lucky to have received this award and luckier still to have worked (and to continue to work) with so many impressive and generous people throughout the atmospheric chemistry community. I owe them all a great deal of thanks.

Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Citation for Sonia I. Seneviratne

If you have ever wondered why heat waves can last that long and whether future climate change will increase droughts, then you should contact Sonia Seneviratne, a talented young scientist whose research is characterized by vigor, deep insight, and a keen eye for the important research questions. In her young career, Sonia has become one of the world's leading experts in the field of atmosphere–land surface interactions. She has already contributed a number of outstanding papers to this rapidly growing field, thereby shaping and influencing it in a defining matter. Sonia has tackled important and fascinating problems associated with the exchange of energy, momentum, and water between the atmosphere and the land surface and identified the key role of soil moisture in controlling heat waves and the onset and duration of droughts. Working at the interface between atmospheric, vegetation, and soil sciences and combining models with data analyses, she has written a number of exceptional papers that are not only novel and interesting but also hugely important for many people and institutions that are affected by droughts and heat waves.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Citation

Gabriel J. Bowen, Josef Dufek, and David Richard Shelly were awarded the 2012 James B. Macelwane Medal at the AGU Fall Meeting Honors Ceremony, held on 5 December 2012 in San Francisco, Calif.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Citation

Joe Dufek is an extraordinary young scientist whose research is characterized by deep intellectual content and rigor. He has contributed significantly to our understanding of the dynamics and petrology of magmatic systems, and to physical volcanology, tectonophysics, and planetary volcanism. Even at such an early stage in his career, Joe's contributions have transformed our understanding of magma chamber dynamics and the physics of volcanic eruption.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Response

Thank you, Jim, and thank you to AGU for this recognition and encouragement. In reality, this award recognizes many who have shared their knowledge, guidance, and example throughout the years.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Citation

David R. Shelly is awarded the 2012 Macelwane Medal for his revolutionary advances in understanding the nature of tectonic tremor and its role in the earthquake preparation process. His innovations in the study of this subtle “noise” from deep within the Earth has opened a new window into the processes governing the earthquake cycle on major plate boundary faults and the magmatic systems beneath active volcanoes.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Response

Thank you, Mark, for your kind words, and thanks also to AGU and the Macelwane committee for this unexpected honor, and to my nominators for their support.

Bowen, Dufek, and Shelly Receive 2012 James B. Macelwane Medals: Response

Thank you, Dave and Jeanne, for the nomination and citation, as well as for being enthusiastic collaborators and mentors over the past few years.
