New Geochemical Perspectives issue: Geobiology
For the 10th anniversary of our publication Geochemical Perspectives, we are excited to publish a special issue presenting a 1944 update of Geobiologie by Lourens Baas Becking. This update was written in pencil over a seven week period while Baas Becking was incarcerated for attempting to escape Nazi-occupied Netherlands.
Lourens Baas Becking was a pioneering microbial ecologist. He coined the term “Geobiology” and was profoundly interested in organisms occupying extremes of temperature and salinity. He is perhaps best remembered for his proposition that “Everything is everywhere, but the environment selects”.
This volume, with its extensive detailed footnotes, brings us into the mind of one of the most important microbial ecologists of the 20th century. This issue also provides the most complete biography of Baas Becking and his fascinating life. We hope that this rather unusual Geochemical Perspectives will serve as both an important historical document as well as an insight into the state of microbial ecology and geobiology in the 1940s.
Considering the length of this issue, it is only published online, so no printed version will be made available. However, with this online format, all footnotes can easily be accessed from the text. Read more about this issue

On the EAG Blog: People’s profiles – Qasid Ahmad
Qasid Ahmad was born in Pakistan and is an Ahmadi-Muslim (i.e. member of the Ahmadiyya Muslim Community). Due to their religion, Ahmad’s family fled from Pakistan and sought asylum in Germany, where they eventually settled near Karlsruhe.
Qasid Ahmad grew up in Germany and after graduating from high school, he studied Applied Geosciences at the Karlsruhe Institute of Technology. Read more
On the EAG Blog: What is – the Atmosphere?
Q1: What is the atmosphere?
A: The atmosphere is a layer of gas covering a planet and other material bodies. Gravity prevents gases that make up the atmosphere from escaping to space (aka. the cosmos). Note: Gravity is a natural force of attraction between all things with mass or energy.
Q2: What is the composition of the Earth’s atmosphere today (also known as air)? Read more
On the EAG Blog: Six questions to Andy Ridgwell
Dr. Andy Ridgwell (University of California, Riverside) writes computer models – numerical representations of the primary interactions of climate with atmospheric CO2, including the cycling of carbon, oxygen, and nutrients between land, ocean, and marine sediments. He applies these models to diverse questions, ranging from geological episodes of extreme glaciation and warming, and global-scale ocean anoxia… Read more

Latest Elements: ‘Heavy Stable Isotopes: From Crystals to Planets’
Stable isotopes are formidable tracers of physicochemical processes at all scales. Steady advances in mass spectrometry have allowed isotopic inquiries to move from the so-called “traditional” systems (i.e., H, C, N, O, and S) to heavier “nontraditional” systems (e.g., Fe, Mo, Ti, Zr, U) whose diverse geochemical characteristics are providing novel and complementary insights. Moving from micron-size systems (single crystals) to planetary-size bodies, the articles in this issue explore the enormous range of temporal and physical scales over which heavy stable isotopes have provided paradigm-shifting insights into the evolution of our planet and solar system. Also highlighted are new frontiers where novel stable isotope systematics appear particularly promising for unraveling long-standing questions. READ MORE
