Early Career Science Ambassador program – next deadline: 1 March
The Early Career Science Ambassador Program is aimed at Early Career Scientists based in Europe who wish to attend conferences held outside Europe (except for the Goldschmidt conference). The program supports up to 6 scientists per year and supported scientists will have 50% of their expenses covered by EAG (up to 1500 euros). The next application deadline is 1 March. More info.

Oxidised micrometeorites as evidence for low atmospheric pressure on the early Earth
P.B. Rimmer, O. Shorttle, S. Rugheimer
Reconstructing a record of the partial pressure of molecular oxygen in Earth’s atmosphere is key for understanding macroevolutionary and environmental change over geological history. Recently, the oxidation state of iron in micrometeorites has been taken to imply the presence of modern Earth concentrations of oxygen in the upper atmosphere at […]
Radiogenic Ca isotopes confirm post-formation K depletion of lower crust
M.A. Antonelli, D.J. DePaolo, T. Chacko, E.S. Grew, D. Rubatto
Heat flow studies suggest that the lower crust has low concentrations of heat-producing elements. This could be due to either (i) greater fractions of basaltic rock at depth or (ii) metamorphic depletion of radioactive elements from rocks with more evolved (andesitic to granodioritic) compositions. […]
Magma properties at deep Earth’s conditions from electronic structure of silica
S. Petitgirard, C.J. Sahle, C. Weis, K. Gilmore, G. Spiekermann, J.S. Tse, M. Wilke, C. Cavallari, V. Cerantola, C. Sternemann
SiO2 is the main component of silicate melts and thus controls their network structure and physical properties. The compressibility and viscosities of melts at depth are governed by their short range atomic and electronic structure. […]
CO2: Earth’s Climate Driver
Wally Broecker
In this new Geochemical Perspectives, Wally recounts the evolution of climate over Earth’s history in six brief episodes, from the early Earth and conditions on our planet under the faint young sun, through the current global warming challenge stemming from the burning of fossil fuels. Along the way Wally reviews some of the major evidence and enigmas of the geologic record and how these have revealed not only the climate of the past, but which processes were critical for this evolution. Through it all, Wally is careful to point out what we feel we now know, as well as research directions that might be most fruitful in the future. Written in a concise and easy to follow text, this should be an enlightening read for experts and novices alike.
