Russian scientists collect, study pieces of meteor
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Russian scientists declared that they have found and established the composition of pieces of the meteor that exploded over the Chelyabinsk region, injuring hundreds of people and causing millions of dollars worth of damage. 53 tiny pieces of dark porous material were collected near Chebarkul Lake, 60 miles west of Chelyabinsk, the regional center, officials said. The biggest of the finds was 7 millimeters long. More

The International Participation Program - Introductory Student GS Membership

GS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Members of the Geochemical Society come from 63 countries, but 95 percent of the membership resides in just 8 regions. To encourage broader international participation, the Geochemical Society is pleased to announce the launch of the first phase of its International Participation Program (IPP) - Introductory Student Memberships. The Introductory Student Membership Program provides a limited number of two-year student memberships in the GS free of charge to students who have not previously been members of the GS and are currently enrolled in a geochemistry related Masters or Doctorate program in countries outside those that currently dominate the GS membership. The introductory student memberships come with all the member benefits of a regular student membership. Please look to the IPP Web page to see if you or one of your students qualify for the introductory memberships and complete an application form.

Support for the IPP comes from generous member donations matched by contributions from the Society. To make a donation, login to your member account and click the donate button on the sidebar. 100 percent of your IPP donation goes into the program and will help the GS communicate the importance of geochemistry to the international community.

Deep Earth Gordon Research Conference Applications Open
   Share    Share on FacebookTwitterShare on LinkedinE-mail article
Applications are now open for participation in the upcoming Gordon Research Conference (GRC) June 2-7, 2013, at Mt Holyoke College (Mass, USA). This year's conference is focused on deep earth and planetary topics and is preceded (June 1-2) by a Gordon Research Seminar (GRS) on the same topic for early career scientists and graduate students. Partial funding for both the GRS and GRC may be available for students/postdocs. Application deadline is May 5, 2013. Early application is recommended, as these unique cutting-edge, inter-disciplinary meetings (GRC and GRS) fill up quickly. Submitted by: Barbara Romanowicz (chair, GRC); Marc Hirschmann (vice-chair, GRC); Maxim Ballmer (chair, GRS). This conference is a recipient of a Geochemical Society Meeting Assistance Grant.

The EMI2013 conference will take place in Ascona (Switzerland) from August 18-23, 2013 in the week before the Goldschmidt meeting in Florence. This conference will assemble the international research community working on stable metal isotope fractionation and its application to environmental geochemistry. Covered topics include the tracing of anthropogenic heavy metal emissions and the investigation of critical zone processes such as chemical weathering and biological cycling, but also other applications of stable metal isotope fractionation to environmental systems will be discussed. Abstract submissions deadline is Friday, March 1, 2013. Submitted by Jan Wiederhold (co-organizer). This conference is a recipient of a Geochemical Society Meeting Assistance Grant.

Climate controversy solved by chemistry? Which volcanic eruptions caused global cooling
Science 2.0    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In the ongoing culture war among climate scientists, climate scientologists and climate deniers, few things stands out like the effect of volcanoes. Volcanoes are well-known for cooling the climate but how much has been unclear, leading to radically differing claims and interpretations. Atmospheric chemists from the Tokyo Institute of Technology and the University of Copenhagen say that patterns of isotopes found in ancient volcanic sulfur trapped in ice cores, and patterns due to stratospheric photochemistry, are a way to say for sure which historic episodes of global cooling were caused by volcanic eruptions.

Wildflowers at risk from 'safe' levels of pollution
Ecologist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New scientific research suggests that the impacts of nitrogen pollution may extend even further than previously thought. Over the last 100 years the global population has increased four-fold to seven billion people and may reach nine billion by 2075. How to produce enough food to feed all these people is one of the biggest global challenges. More

NASA launches powerful Earth-observing satellite

Is the Earth cooking up a super volcano?
WFAE-FM    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Every few million years or so, the Earth burps up a gargantuan volcano. These aren't like volcanoes in our lifetimes; these "super volcanoes" can erupt continuously for thousands of years. While they might be rare, you'd best look out when one hits. The ash and volcanic gases from these volcanoes can wipe out most living things over large parts of the planet. Michael Thorne, a seismologist at the University of Utah, has some clues about what causes these big eruptions. More

Mercury's 'dynamic and complex world' revealed by NASA's Messenger
The Guardian    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Mercury is the smallest of the solar system's eight planets and, for decades, also its most neglected by humans. While Mars, Venus, Jupiter and Saturn have been probed and photographed in exquisite detail during the space age, the closest planet to the Sun has had to make do with a few flybys from the Mariner 10 spacecraft in the early 1970s.

British researchers find odd, cold volcanic vent in Antarctic waters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Hydrothermal vents are like hot springs, spewing jets of water from the seafloor out into the ocean. The expelled water, if hot enough, is rich in dissolved metals and other chemicals that can nourish a host of strange-looking life, via a process called "chemosynthesis." The hot water, being more buoyant than the surrounding cold seawater, rises up like a fountain or "plume," spreading the chemical signature up and out from the source. More
