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.

CORES Study Seeks Community Input

January 10, 2019

The U.S. National Academies of Sciences, Engineering, and Medicine is now conducting a study on Catalyzing Opportunities for Research in the Earth Sciences (CORES), sponsored by the National Science Foundation's Division of Earth Sciences.

The purpose of the CORES study is to (1) identify a concise set of high-priority scientific questions for the next decade, (2) assess infrastructure needed to address these questions, and (3) determine opportunities for greater collaboration with other NSF divisions and directorates, federal agencies, and domestic and international partners.

The CORES committee is soliciting input through a questionnaire about upcoming research priorities and GS members are encouraged to submit their ideas:

Meet the Scientist: Jesse Reimink

December 13, 2018

Name: Jesse Reimink
Title: Postdoctoral Scholar
Institution: Carnegie Institution for Science
Place of residence: Washington, DC


Q: What kind of science do you do?
A: I am a geologist and geochemist working on understanding how continents were formed on our planet, particularly on the early Earth. My work includes fieldwork and primary sample collecting, as well as developing new analytical techniques that can be applied to existing sample sets. I can be somewhat distractible scientifically, but I think that is a feature of how interesting our field is and maybe not the worst thing in the world!

Jeff Catalano Named Executive Editor of GCA

December 06, 2018

The Geochemical Society and the Meteoritical Society are pleased to announce the appointment of Jeff Catalano, Professor of Aqueous Geochemistry and Mineralogy at Washington University in St. Louis, as the next Executive Editor of Geochimica et Cosmochimica Acta. He will succeed outgoing EE Marc Norman, whose six-year tenure has been marked by steadily rising submissions and impact factor for GCA. Prof. Catalano's term will officially begin on 1 January 2019.

Meet the Scientist: Asmaa Boujibar

October 25, 2018

Name: Asmaa Boujibar
Title: Postdoctoral Associate
Institution: Geophysical Lab, Carnegie Institution for Science
Place of Residence: Washington, DC

Q: What kind of science do you do?
A: I am a petrologist, geochemist and planetary scientist. I study several aspects of planetary accretion and differentiation. I perform experiments at high pressure and temperature to simulate conditions under which planets form and evolve. Using experimental data, I model the chemical reactions occurring during planetary growth and the resulting physical states of planetary interiors. The main goal of my work is to understand how and why each terrestrial planet of our solar system and beyond are different in chemical composition, structure, thermal state and geologic history. Using meteoritic data, I also help unravel the differences between planetary, asteroidal and meteoritic compositions, which enables a better knowledge of the dynamic evolution of our solar system in its early stages.

Elements: Deep-Ocean Mineral Deposits

October 11, 2018

Ferromanganese nodules/crusts and seafloor massive sulfides are a unique feature of the deep-ocean seafloor. These deep-ocean mineral deposits are windows into Earth's processes, revealing clues to the evolution of seawater and ancient ore-forming processes. They also represent significant metal resources that could contribute future raw materials supply. The articles in this issue explore the formation of deep-ocean mineral deposits; their inherent scientific value; and the geological, technical, environmental and economic challenges, as well as regulatory and philosophical questions, of extracting such mineral resources.
