v18n1 From the Editors

 THIS ISSUE: HALOGENS

In this issue, we follow the halogen group elements (fluorine, chlorine, bromine, and iodine) from the Earth’s interior to surface—and even beyond! In a similar vein to two previous Elements issues that also explored groups of elements united by common properties (Rare Earth Elements; October 2012 and Platinum Group Elements; August 2008), this issue similarly showcases the wide diversity of research that is encompassed by halogen mineralogy and geochemistry. Over the last several decades, the halogens have increasingly come into the spotlight, possibly due to improving methods for measuring ultra-low abundance bromine and iodine in geologic materials, as well as isotopes of chlorine and bromine. The result of this increased enthusiasm for halogens is deftly covered over six articles by this issue’s authors—from halogens in Earth and planetary systems to experimental petrology and analytical developments, there truly is something for everyone.

This issue further highlights how halogens are relevant to society and human health, ranging from their role as essential elements to human health, to the more detrimental impacts of halogen emissions and radionuclide contamination. Eleven years ago, the Fukushima Daiichi Nuclear incident occurred on March 11, 2011, which prompted an Elements issue (Fukushima Daiichi; June 2012) the following year. On the ten-year anniversary of this issue, we revisit the specific impact of iodine radionuclide contamination in this issues’ Perspective by Takeshi Ohno.

RISING LEADERSHIP

Catherine (Cari) Corrigan

Catherine (Cari) Corrigan

Dear Elements readers,
I would like to introduce myself as the next Chair of the Elements Executive Committee. First, however, I’d like to thank our outgoing chair, Dan Frost, for his years of service to Elements, and for a job well done. I have been working with Elements since 2011 as the representative for the Meteoritical Society. In that time I have compiled the Met Soc Society news and worked on the CosmoElements feature (3x per year). I also co-edited the “Asteroids” issue in 2014. Working with Elements has been a great way to stay involved with the greater geologic community, both by working with representatives from other societies all over the world, and by reading the issues as they come out. As we all know, once we leave formal schooling it becomes much more difficult to stay current on the broader aspects of one’s field, and Elements is a great way to overcome that hurdle. In addition, it has allowed me to become more involved in my society, and to get to know more of its members than I would have otherwise, including both the newer generation of researchers and those in more advanced stages of their careers.

Since 2008, I have been a research geologist and the curator of Antarctic Meteorites at the Smithsonian Institution’s National Museum of Natural History in Washington, DC, USA. My research centers around the U.S. Antarctic Meteorite Collection, and has included work on a wide variety of meteorites and meteorite types, including the process of impact and how it has affected the evolution of the planetary materials within our Solar System. As a bonus of working in a large museum collection, I have been able to work on newly discovered meteorites and have also had the privilege of being able to delve into some of the history of our meteorite collection. I spend a significant portion of my time mentoring interns and fellows, as well conducting outreach to students and the greater public and Elements has been a big part of that outreach for me for over a decade.

I look forward to working with you to keep Elements moving into the future as the high quality publication we’ve all come to know and love.

Sincerely,
Catherine (Cari) Corrigan

WELCOMING JANNE BLICHERT-TOFT

Janne Blichert-Toft

Janne Blichert-Toft

We are delighted to welcome Janne Blichert-Toft as the 2022–2024 geochemistry principal editor with Elements. Janne is an isotope geochemist and has served as a research director at CNRS at the Ecole Normale Supérieure de Lyon (France) since 1997. Janne completed her Ph.D. at the University of Copenhagen (Denmark) in 1993 and her Habilitation à Diriger des Recherches at Université Claude Bernard Lyon 1 (France) in 2000. Her research focuses on radiogenic and stable isotopes and dating techniques to constrain the origin and evolution of the Earth and other planetary bodies in the Solar System, extending also into crude oil provenance, geoarchaeology, and numismatics. She further applies isotopic data from archaeological settings and artifacts to address controversial historical questions, such as why the Roman empire collapsed, how Carthage survived the Punic wars, and what were the origins of the silver looted by Alexander the Great in his conquest of the Persian Empire. Janne is currently working with the guest editors of the “Cement and Concrete: From the Romans to Mars” issue, which is scheduled for October 2022.

NEW FACES, NEW FEATURE

Esther Posner

Esther Posner

Please join us in warmly welcoming Esther Posner to the Elements Editorial Team. Esther earned her M.S. in Geosciences at the University of Arizona (USA) in 2012 and Ph.D. in Experimental Geoscience at the Bayerisches Geoinstitut at the Universität Bayreuth (Germany) in 2017. Esther’s passion for geoscience is uniquely complimented by her flair for the written word: she is an internationally acclaimed academic editor—having professionally edited more than 1000 scientific manuscripts—and is also an award-winning performance
poet and composer. With Esther’s oversight, Elements is defining a new platform for geoscience-inspired poetry/prose in our bi-annual GeoScience Slam feature. Be sure not to miss her rhyming rendition of the geological time scale on page 70 of this issue.
