Ancient rocks show life could have flourished on Earth 3.2 billion years ago
University of Washington via EurekAlert
A spark from a lightning bolt, interstellar dust or a subsea volcano could have triggered the very first life on Earth. But what happened next? Life can exist without oxygen, but without plentiful nitrogen to build genes — essential to viruses, bacteria and all other organisms — life on the early Earth would have been scarce.

Miriam Kastner named 2015 V.M. Goldschmidt Medalist
GS
Miriam Kastner, Distinguished Professor in the Scripps Institution of Oceanography University of California San Diego has been selected as the recipient of the 2015 V.M. Goldschmidt Award. 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. Dr. Kastner is recognized for her fundamental contributions to our understanding of crust-fluid interactions, particularly in subduction zones and ridge flanks; for the breadth of her research achievements, spanning a wide range of geochemical processes occurring at the sediment-water interface and within marine sediments (gas hydrates and methane cycling, dolomitization, Si, Ca and P mineral diagenesis); and as a rigorous and innovative geochemist who has always set extremely high standards. This award will be presented at the Goldschmidt2015 conference in Prague, Czech Republic this August.

Anat Shahar named 2015 F.W. Clarke Medalist
GS
Anat Shahar, Science Staff at the Geophysical Laboratory at the Carnegie Institution of Washington has been selected as the recipient of the 2015 F.W. Clarke Award. 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. Shahar is recognized for her significant experimental advances; her incredibly challenging yet elegant high P-T experiments; and her innovative ability to measure silicon isotopes in situ constraining the melting history of each object within.

Karen Johannesson named 2015 C.C. Patterson Medalist
GS
Karen Johannesson, Professor of Geochemistry and Chemical Hydrogeology at Tulane University has been selected as the recipient of the 2015 C.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. Johannesson is recognized for her papers in which she established new insights into REE aqueous geochemistry. Specifically, the breadth and depth of her work on quantitatively assessing REE complexation and fluxes, as developed through her insights into how REE speciation controls the distribution and mobility of REE in aqueous systems. This award will be presented at the Goldschmidt2015 conference in Prague, Czech Republic this August.

Ancient shells offer evidence of how Ice Age ended
Climate News Network
Scientists believe they may have cracked the mystery of the end of the last Ice Age. The temperatures suddenly soared, and the glaciers went into retreat, because the deep southern ocean released huge quantities of carbon dioxide. And the convincing answers have been delivered by analysis of the composition of calcium carbonate shells of ancient marine organisms.

Floods created home of Europe's biggest waterfall, study shows
University of Edinburgh via EurekAlert
A massive canyon that is home to Europe's most powerful waterfall was created in a matter of days by extreme flooding, new research reveals. The Jökulsárgljúfur Canyon in Iceland, which is 28 km long and 100 meters deep in places, was formed by a series of distinct floods that occurred thousands of years apart, a study shows.

GEOTRACES Survey
GEOTRACES
GEOTRACES is an international project that is creating a detailed baseline of the global distribution of trace elements and isotopes in the ocean. GEOTRACES released its first Intermediate Data Product at the Ocean Sciences meeting in February 2014 in Honolulu, Hawaii, USA. GEOTRACES is seeking feedback about its first Intermediate Data Product by means of a short (5 minute) survey. The purpose of this survey is to assess the processes used for this first release in order to improve the processes used in the next release, expected in 2017. The survey should only take about 5 minutes to complete. Please respond by Feb. 28. Visit our website for more information about GEOTRACES Intermediate Data Product.
