New Geochemical Perspectives: Sulfur Biogeochemical Cycle of Marine Sediments

Call for 2022 award nominations: we need your help to increase diversity and inclusion

Call for 2022 Award Nominations open

The EAG recognizes outstanding contributions to geochemistry at different career stages through several EAG awards and joint EAG & GS awards. In addition to scientific excellence, several awards also recognize the broader impacts candidates have made to the community at large.

However to improve the diversity of our awardees we first and foremost need to raise the number of nominations so we also need your help! The nomination process is open to all and has recently been simplified. Find out more about how to make a nomination

Geochemistry Fellows nomination deadline: 31 October
Urey, Houtermans, Science Innovation awards nomination deadline: 15 November

EAG needs you to nominate a colleague for an award today! Message from the EAG President

The European Association of Geochemistry recognizes excellent contributions to the discipline of geochemistry, excellent contributions of all kinds. Our aim is fairness, equity and diversity in our awards system, but some of these aims are hampered by a lack of nominations. We need your help. Read more

EAG Council Elections now in progress

EAG members are currently asked to cast their vote to select three new councillors amongst six candidates. Our councillors participate in discussions, decisions, and initiatives, so they play a crucial role in determining the future of the society. Therefore, participation is essential to the success of these elections and we thank our members for taking a few minutes to vote.

EAG members: if you have not voted yet, your personalized link to vote was sent by email on 11 October. If you have not received it, please contact the EAG Office.

Latest Geochemical Perspectives : ‘Sulfur Biogeochemical Cycle of Marine Sediments’

On the background of his own studies of the sulfur cycle over the past forty years, Bo Barker Jørgensen discusses important aspects of the microbiology and geochemistry of sulfur transformations in the seabed. Mixed with anecdotes, he reminisces how the field developed, with exciting discoveries and occasional failures. There is particular focus on experimental approaches and their use to understand sulfate reduction, sulfide oxidation, and disproportionation. Interactions with the methane cycle and with general mineralisation processes are described, and the information provided by stable sulfur isotopes is discussed. The final sections analyse global aspects and future perspectives of the sulfur cycle. READ MORE

Latest Elements: ‘Exploring Earth and Planetary Materials with Neutrons’

For over half a century, the structural details and the dynamics of atomic arrangements in materials have been determined using neutron-based scattering and absorption measurements. Neutron scattering experiments have contributed valuable information on geological materials and how these interact with fluids. In situ studies of transformations and fundamental properties can emulate diverse environments from Earth’s surface to its deep interior. Potential growth of the “neutron community” is being realized with the development of new and improved neutron sources. This issue will familiarize the reader with the basic concepts of neutron scattering, the methods that are available to Earth scientists, provide a summary of facilities around the world, and give key applications of the technique.
