RIMG #75: Carbon in Earth released as an open access publication
Carbon in Earth is a product of the Deep Carbon Observatory (DCO), a 10-year international research effort dedicated to achieving transformational understanding of the chemical and biological roles of carbon in Earth. The book integrates a vast body of knowledge and research in physics, chemistry, biology and Earth and space sciences about carbon. A small fraction of Earth's carbon is in its atmosphere, seawater and top crusts. An estimated 90 percent or more is locked away or in motion deep underground - a hidden dimension of the planet as poorly understood as it is profoundly important to life on the surface. Each chapter synthesizes what we know about this deep carbon, and also outlines unanswered questions that will guide the DCO's research for the remainder of the decade and beyond. A hallmark of the DCO is the desire to implement advanced strategies in communications, data management, engagement, and visualization. Accordingly, this volume incorporates some novel aspects of animations and videos. Thanks to sponsorship by the Alfred P. Sloan Foundation, which provides significant support for the DCO, this is the first of the RIMG series to be published as an Open Access volume. Print copies are also available for purchase for US$ 40.00. Geochemical Society members receive a 25 percent discount on RIMG orders.

The death of the Chebarkul meteor
The city of Chelyabinsk was once a secret Soviet weapons center, then a poor Siberian backwater. But a few minutes after sunrise on Feb. 15, the largest meteor blast in more than 100 years lifted the region from obscurity. Since then, scientists have been scrutinizing fragments of the meteorite and studying videos of its final moments to pin down its origin and how it got to Earth.
Earth not so hot thanks to volcanoes
Global average temperatures have been rising in recent years, but not as much as they might have, thanks to a series of small-to-moderate-sized volcanic eruptions that have spewed sunlight-blocking particles high into the atmosphere. That's the conclusion of a new study, which also finds that microscopic particles derived from industrial smokestacks have done little to cool the globe.
Forests as rainmakers: New study lends credence to theory
The Energy Collective
It seems intuitive that large forests exist in areas where there is a lot of rainfall. But what if the converse were true? What if forests themselves were a significant factor in causing rainfall?
Europa's epsom salt may indicate ocean life
If you've ever found yourself wanting to know if there's extraterrestrial life on Europa, this latest study into the Jovian moon's icy crust should whet your appetite.
Using data from the powerful Keck II Telescope atop Mauna Kea in Hawai'i, astronomers Mike Brown, of the California Institute of Technology (Caltech), and Kevin Hand, of NASA's Jet Propulsion Laboratory (JPL), have found strong evidence that suggests chemicals from Europa's sub-surface ocean are leaking to the surface. In turn, chemicals from the surface are likely cycling into the ocean too. The research has been published in the Astrophysical Journal.
