Sylvie Derenne Named 2019 Alfred Treibs Medalist

March 06, 2019

Dr. Sylvie Derenne of CNRS and Sorbonne Université (France) will receive the 2019 Alfred Treibs Award this summer. Presented by the society's Organic Geochemistry Division, the award is given for major achievements, over a period of years, in organic geochemistry. Dr. Derenne  is recognized for her research on the selective preservation of algal cell walls to form kerogen and the hypothesis that carbonaceous chondrite organic matter derives from solar gases and dust. She will accept the award at the International Meeting on Organic Geochemistry (IMOG) in September.

Don DePaolo Named 2019 V.M. Goldschmidt Medalist

February 28, 2019

Don DePaolo, Graduate Professor of Geochemistry and Chancellor's Professor Emeritus at the University of California, Berkeley (USA), will receive the 2019 V. M. Goldschmidt Award this summer. The Goldschmidt Award recognizes major achievements in geochemistry or cosmochemistry consisting of either a single outstanding contribution or a series of publications that have had great influence on the field. Prof. DePaolo is recognized for outstanding contributions to the development of new isotopic methods and their application to crust and mantle evolution, igneous and metamorphic petrology, ocean chemistry and reactive chemical transport. The award will be formally presented at the 2019 Goldschmidt Conference in Barcelona this August.

Barbara Sherwood Lollar Named 2019 C.C. Patterson Medalist

February 28, 2019

Barbara Sherwood Lollar, University Professor at the University of Toronto (Canada), has been named the 2019 recipient of the Clair C. Patterson Award. The Patterson Award recognizes an innovative breakthrough of fundamental significance in environmental geochemistry, particularly in service of society, consisting of either a single outstanding contribution or a short series of papers published within the last decade. Dr. Sherwood Lollar has pioneered environmental geochemistry methods based on compound specific isotope analysis to detect and monitor the biodegradation of organic pollutants in water. These methods have reshaped the assessment of contaminated sites world-wide and have provided a molecular-level technique to improve the sustainability of water resources.

Thomas Kruijer Named 2019 F.W. Clarke Medalist

February 28, 2019

Thomas Kruijer, a postdoctoral research scientist at the Lawrence Livermore National Laboratory (USA), will receive the 2019 F.W. Clarke Award this summer. The Clarke Award recognizes an early-career scientist for a single outstanding contribution to geochemistry or cosmochemistry published either as a single paper or a series of papers on a single topic. Dr. Kruijer is recognized for his groundbreaking work on the Hf-W
chronometer to discover the remarkably early differentiation and protracted accretion of planetesimal cores, and possible age of formation of Jupiter, and the discovery of distinct provenances of iron meteorites based on W-Mo nucleosynthetic anomalies. The award will be formally presented at the 2019 Goldschmidt Conference in Barcelona this August.

Meet the Scientist: Zie Ouattara

February 21, 2019

Name: Zié Ouattara
Title: Assistant Professor
Institution: University of Man, Côte d'Ivoire
Place of Residence: Man, Côte d'Ivoire

 

What kind of science do you do?
I am a metallogenist and geochemist. My work is to better understand the mineral resources (particularly gold) and define the footprints that can be helpful to the exploration teams as well as the academic researchers. My daily challenge is to realize field work, collect samples, undertake laboratory work and synthetize data from several origins including lithostratigraphy, alteration, fluids inclusion, structural, metamorphism and geochemistry in order to build a model that can summarize a mineral deposition history.

Elements: Planet Mercury

February 11, 2019

Mercury is unique among terrestrial planets because of its very high metal/silicate ratio. The NASA MESSENGER mission ended in 2015 and significantly advanced our understanding of the deep structure of the planet as well as our comprehension of Mercury's volcanic history and crust formation. The European Space Agency (ESA) recently launched the BepiColombo mission in October 2018. This issue summarizes the latest developments in light of MESSENGER data and perspectives for the BepiColombo mission on internal structures and surface processes, based on insights from geophysics, geochemistry, igneous and experimental petrology and volcanology.

Meet the Scientist: Dominique Weis

January 24, 2019

Name: Dominique Weis
Title: Professor, Canada Research Chair Tier I, FRSC
Institution: University of British Columbia
Place of Residence: Vancouver
Website: http://pcigr.eos.ubc.ca/Dominique-Weis/

What kind of science do you do?
I am a geologist by training and a geochemist in practice applying geochemical fingerprinting to constrain the geochemical evolution of our planet and its main reservoirs, to evaluate the impact of pollution on the environment, and to train young scientists in geochemistry to be leaders in the workforce. Such research requires unprecedented precision and sensitivity for the analysis of elemental concentrations and isotopic ratios in rocks, minerals, water, and organic matter that can only be provided by modern instruments (e.g., mass spectrometers). Importantly, these tools can be applied to many areas of study, including the relationship between our environment and human health.

GS Adopts Code of Ethics

January 15, 2019

The GS board of directors approved the society's first code of ethics in December, following more than a year of research and discussion. The code helps define the values of scientific and professional integrity that the society has been committed to since its founding. All members are encouraged to read it.

Elements: Marine Biogeochemistry of Trace Elements and Their Isotopes

January 10, 2019

The field of marine geochemistry is exploding these last two decades. During the 1980s and 1990s, the scientific community developed a geochemical toolbox to study key ocean processes, based on the concentration and isotopic composition of trace elements. The multiple processes at play in the ocean led the community to join forces and combine, at a global scale, the information provided by individual tracers to tackle big questions in oceanography. These were the motivations to create GEOTRACES, an international program of marine geochemistry. The key questions include the sources, internal processes and sinks of the elements; the services and functioning of marine ecosystems; the ocean's role in climate variability; and the transport and fate of contaminants in the ocean. This issue will introduce the reader to the fascinating exploration of the big questions in ocean science using the chemistry of the infinitely small in seawater.
