New Lecture Honoring Robert Berner
October 05, 2016
Students and friends of the late Bob Berner are working to establish an annual lecture at the Goldschmidt Conference to commemorate his intellectual legacy in geochemistry. The lecture will be on a 'Berner' subject, which includes a wide range of topics associated with elemental cycling at the Earth's surface (molecular to planetary scale, modern to ancient oceanic and terrestrial systems, evolution of the biosphere, etc). The lecturer will be selected jointly by the Geochemical Society and the European Association of Geochemistry. Contributions will go directly to supporting the lecturer's travel to Goldschmidt every year.

Five years have passed in Fukushima, but numerous long-term issues still remain
March 09, 2016
Five years ago, the Great East Japan Earthquake hit the Tohoku district causing 19,335 deaths; 2,600 people are still missing. The Fukushima Daiichi Nuclear Disaster, at level seven on the International Nuclear Event Scale (INES), released ~520 PBq of radionuclides and forced residents to evacuate miles away from the contaminated area. During the past five years, a large number of articles have been published on the earthquake and the subsequent events, including the radioactive Cs contamination on the land in Fukushima prefecture and in the ocean (geochemical NEWSin August 25, 2015).
Radioactive Cs contamination in the surface environment has been a serious issue and will remain so for decades to come given the half-lives of 134Cs and 137Cs are 2.06 and 30.07 years, respectively. Radioactive Cs is rigidly bound in interlayers of clay minerals and is retained in the surface soils (e.g., Kaneko et al., 2015). However, aircraft monitoring revealed that the radiation dose decreased faster than expected based on the Cs half lives (Fig. 1b), indicating that soil particles associated with Cs were transported through surface waters into the ocean (e.g., Yamasaki et al., 2016). In addition to Cs bound to clay minerals, Cs-rich micro-particles (~ a few μm), mainly composed of Si oxide glass associated with wt% level Cs and other metals, were recently reported (Adachi et al., 2013). Despite their low numbers, these Cs-rich micro-particles may be a considerable dose contributor to the ecosystem. In addition, the formation processes of these Cs-rich micro-particles can provide novel information on the reaction that happened inside the reactor pressure vessel (RPV) and the primary containment vessel (PCV) when the fuels melted down in units 1 and 3 at the Fukushima Daiichi Nuclear Power Plant (FDNPP). The decommission of units 1~4 is ongoing and the most difficult process will be the removal of fuel debris, which is a solidified form of the melted fuel mixed with cladding, other metals, and possibly concrete. Even the occurrence and properties of the debris are totally unknown at the present, because it is difficult to sample the debris and investigate the occurrence inside the PCV due to the extremely high radiation dose. Since the Cs-rich micro-particles contain some fission products, they provide valuable insights into the chemical reactions that occurred inside the PCV during the explosions. The Fukushima disaster will challenge many geochemists as the long-term issues including debris, contaminated water stored in tanks, and Cs contamination in the soils, are resolved.

Ian D. Hutcheon, Deputy Director of the Glenn Seaborg Institute and Group Leader of the Chemical and Isotopic Signatures Group in Nuclear and Chemical Sciences Division in the Physical and Life Sciences (PLS) Directorate of Lawrence Livermore National Laboratory, passed away March 26, 2015. He was 67 years old.
Hutcheon earned his PhD in Physics from the University of California, Berkeley in 1974. His expertise with the ion probe began to develop at the University of Chicago when he worked with Joe Smith and then expanded further when he moved to Cal Tech in 1983 to work with Jerry Wasserburg on the applications of secondary ion mass spectrometry to cosmochemistry. He moved to Lawrence Livermore National Laboratory in 1993.
Hutcheon made numerous contributions to the study of the isotopic composition of meteorites and what they reveal about the evolution of the early solar system. He was also a key developer of nuclear forensics as both a field of scientific investigation and a scientific discipline with significant applications to national security. He conducted groundbreaking work in the formation mechanisms of planets and meteorites, diffusion transport processes in terrestrial and planetary melts, glasses and minerals; and conducted the first NanoSIMS-enabled studies of biological materials. He authored over 200 papers and book chapters, and co-wrote the textbook, Nuclear Forensics Analysis with colleagues Pat Grant and Ken Moody.
His awards in recent years included being named, in 2013, a Distinguished Member of Technical Staff at the Laboratory; receiving the Physical and Life Sciences Outstanding Post-doc Mentor award in 2010; and having a newly discovered mineral in the Allende meteorite named in his honor, Hutcheonite. He was named a Fellow of the Meteoritical Society in 1986.
In his 22 years at LLNL, he built the Chemical and Isotopic Signatures Group from himself and 2 others and one secondary ion mass spectrometer to 38 scientists, post-docs, graduate students and technicians. The breadth of study within the members of his group includes time scale and processes of nucleosynthesis; formation and evolution of meteorites and planets; mineralogy and petrology of unequilibrated meteorites; sub-cellular imaging of biological samples and isotope tracing into cells of all types; environmental microbiology; nuclear forensics and attribution.
In recent years Hutcheon and members of his group were involved in establishing collaborations with colleagues at analytical facilities in South Africa, Canada, the UK, and with the IAEA, to help encourage nuclear forensics efforts.
Ian Hutcheon is survived by his wife of 41 years, Nancy Hutcheon, former Education Coordinator for summer internships in PLS, his children, Douglass Hutcheon and Dana Gordon, and hundreds of colleagues in the US and abroad, that he mentored and inspired to scientific excellence.

Robert Berner (1935 - 2015)
January 13, 2015
Dear G&G Community:
I write to bring you the sad news that Robert A. Berner, Emeritus Professor of Geology and Geophysics, passed away as a result of pneumonia this weekend. We extend our deepest, heartfelt condolences to his family at this most difficult time.
Bob got his B.S. and M.S. degrees from the University of Michigan, and his Ph.D. from Harvard. He did a postdoc at the Scripps Institution of Oceanography before moving to the University of Chicago as an Assistant Professor in 1963. He came to Yale in 1965, and stayed here for the rest of his career.
Bob was one of the greatest geochemists and, more broadly, geologists who ever lived. It is simply impossible to list all of his accomplishments. Much of his research centered on the quantitative geochemistry of sediments, and it's not an exaggeration to say that he defined the field as we know it. He made seminal contributions to, for example, the geochemistry of sulfides and carbonates in the oceans, diagenesis, weathering, and geochemical cycling. He was a thoughtful teacher and mentor, inspiring a whole generation of geochemists who got their Ph.D.'s or did their postdoctoral research in his lab. Today the students of Bob's students are now making their impact on the field!
Bob's research in any one of the areas he studied would have made a spectacular career. The fact that he made such fundamental contributions to so many areas makes his achievements and legacy all the more remarkable. Arguably his broadest impact has been in the area of carbon cycling. For example, Bob spearheaded the quantitative interpretation of the CO2 content of the atmosphere over the last 600 million years of Earth history. His work provided the basis for virtually all modern carbon cycling research going on today. This understanding of past CO2 levels and paleoclimates has provided an invaluable baseline of comparison for determining the impact of today's anthropogenic CO2 emissions on the atmosphere and the associated climate change.
Bob served the field of geochemistry as the President of the Geochemical Society, and received countless accolades (Guggenheim Fellow; Member, National Academy of Sciences; and many, many others). Bob's long association with the American Journal of Science (Silliman's Journal) as Associate Editor or Editor held special significance for him; indeed, many of his most influential papers were published there.
Bob had a tremendous sense of humor and could talk about almost any topic with enthusiasm and insight. He was an expert on wine (including it's chemistry!) and loved music. Given the importance of what he worked on regarding atmospheric chemistry and carbon cycling, he attracted quite a bit of media attention. I remember one instance where the news media had become very interested in his research on trapped air samples in ancient amber. Part of this translated into print as something along the lines of: Scientists Capture Dinosaur Breath! Bob thought that was hilarious and we all had a great laugh over it too.
I remember a dinner in Bob's honor some years ago. Many of his family members were present. He was holding one of his grandchildren in his arms, pontificating about some great insight he had had about geochemistry. And the little baby just reached up and grabbed his nose. He immediately dissolved into the world of that baby---the science left his mind and you could see how the love that he had for his family was such an integral part of what made him so special.
In accordance with the family's wishes, in lieu of flowers, please consider making a donation in Bob's name to the Geology and Geophysics Graduate Research and Field Studies fund. You can send these by mail to the G&G Chair's office c/o Rebecca Pocock. I highly recommend Bob's fascinating autobiography, which can be found here: http://people.earth.yale.edu/sites/default/files/files/Berner/Robert%20A_%20Berner%20Autobiography.pdf
Sincerely,
Jay

Broadening the Diversity of Excellence as we head to Awards Nomination Deadlines (Oct 31 2014)
October 03, 2014
Dear Members of the Geochemical Society,
In the next few weeks we face the deadlines for submission of nominations for the GS's highest competitive honours (October 31 2014). Having the most deserving and most diverse group of award winners is important for many reasons. Awardees symbolize the highest achievement in our field. They inspire all of us, and especially those at an early career stage, to do our best science. They become among the most visible spokespersons for our profession.
This is where you come in.
The development of a large and competitive pool of excellent nominees is critical to the success of the prize competitions. To develop these pools we ask that you in the community bring to bear all your scientific expertise and creative thinking. The past record of prize winners reflects scientific excellence and achievement of the highest level. Putting together a nomination package is not onerous, and unless you choose to reveal your role, is anonymous. There can be no more important role in leading and mentoring scientific accomplishments and recognition in the field of geochemistry.
There is a second important issue I hope to bring to your attention and thereby to mobilize the collective resources of our community to address. The record of achievement the Geochemical Society recognizes through prizes, plenaries and keynotes at Goldschmidt has been exemplary. But a quick look at overall past statistics also reveals that historically, our recognitions and honours have been very much focused on our European and North American membership despite the fact that more than 20% of our membership draws from outside these regions and despite a community membership which reflects a much wider range of diversity of all descriptions (gender, heritage, discipline) as well as geographic.
See earlier Elements Comments by Past-GS President Sam Mukasa on this and related topics from April 2009.
We would like to urge you now to get involved to help ensure all aspects of the Geochemical Society's activities, including prizes continue to reflect the full diversity of scientific excellence and professional achievement that is out there in our community. It is a normal human tendency to self-replicate. When asked to brainstorm a list of names for recognition of scientific excellence my own initial list would no doubt reflect too many groundwater geochemists, likely too many women, and certainly too many Canadians! Those who have studied this issue suggest are simple steps that can help us broaden our collective perspective.
Steps Forward:
Draw up your initial brainstorming list, then step back and think again – more broadly this time. Consider excellent scientists you know who are significantly different than yourself and those who you studied with and postdoc'ed with, and add those names to your nomination list. Our goal this year is to have no fewer than 5 nominees considered for each award and 30 in the consideration pool for GS Fellows.
- We can do better in the nominations phase.
- We need your expert judgement and creative vision.
- Get involved this year.
- Make a resolution to continue your involvement annually and nominate one excellent candidate each year
for something, whether it be within GS or elsewhere.
- We are counting on your leadership and vision. Your role as a scientific mentor and supporter can
change the world (https://www.geochemsoc.org/awards).
With best wishes, Barbara Sherwood Lollar
GS President (2014-2015)
GSJ formalizes relations with GS and EAG
December 13, 2013
The Geochemical Society of Japan (GSJ) held a signing ceremony with the Geochemical Society (GS) and the European Association of Geochemistry (EAG) at the recent Fall AGU meeting in San Francisco, USA. The signed agreements intend to build collaborative activities between the three organizations in general and specifically with the V.M. Goldschmidt Conference. In attendance for the ceremony were President-Elect Hodaka Kawahata (GSJ), President Chris Ballentine (EAG), Vice-President Barbara Sherwood Lollar (GS), President Rick Carlson (GS), and President Naohiro Yoshida (GSJ).
Award Nomination Diversity
September 09, 2013
Do you feel that many scientific awards lack diversity? We couldn’t agree more. Please read Sam Mukasa's Triple Point from 2009 for recent statistics. Unfortunately no significant improvement has been achieved since. Why? A major reason is too few take the time to nominate worthy candidates for Society recognition. Do something about it and help us break this trend by making a nomination. Nominations are easy and the nomination deadline is October 15.
