EAG endorses Africa Initiative for Planetary and Space Sciences

africaResearch groups in Planetary and Space Sciences are now emerging in Africa, but remain scattered and underfunded. To elevate planetary and space science across the entire African continent, a group of researchers propose an Africa Initiative for Planetary and Space Sciences. It will involve coordinated actions with international partners for training M.Sc. and Ph.D. students, for developing locally-based scientific facilities, and for the progressive integration of the fascinating discoveries about our Solar System into University curricula.
The identified benefits of education and research programs in Planetary and Space Sciences and the call for endorsement of this initiative are presented in two articles recently published in EOS (Africa Initiative for Planetary and Space Sciences and The State of Planetary and Space Sciences in Africa).
EAG is excited to announce the formal endorsement of this initiative, alongside with several other professional organisations.

2017 EAG Distinguished Lecture Program: applications open

Lenny WinkelFollowing the announcement of Prof. Lenny Winkel (ETH Zurich) as this year’s Distinguished Lecturer, we would like to remind institutions in Central and Eastern Europe that they can apply to invite her to present one or two lectures during the tour this fall. Read more details.

Reorganisation of Earth’s biogeochemical cycles briefly oxygenated the oceans 520 Myr ago
T.W. Dahl, J.N. Connelly, A. Kouchinsky, B.C. Gill, S.F. Månsson, M. Bizzarro

The Phanerozoic radiation of bilaterian animals has been linked to oxygenation of Earth’s oceans, due to the oxygen demand of the evolving animal ecosystems. However, how early animals may have regulated Earth’s surface oxygen budget via self-stabilising feedbacks is poorly understood. […]

Abstract GPL1725_100Not so non-marine? Revisiting the Stoer Group and the Mesoproterozoic biosphere
E.E. Stüeken, E.J. Bellefroid, A. Prave, D. Asael, N.J. Planavsky, T.W. Lyons

The Poll a’Mhuilt Member of the Stoer Group (Torridonian Supergroup) in Scotland has been heralded as a rare window into the ecology of Mesoproterozoic terrestrial environments. Its unusually high molybdenum concentrations and large sulphur isotope fractionations have been used as evidence […]

Abstract_GPL1726_100Global climate stabilisation by chemical weathering during the Hirnantian glaciation
P.A.E. Pogge von Strandmann, A. Desrochers, M.J. Murphy, A.J. Finlay, D. Selby, T.M. Lenton

Chemical weathering of silicate rocks is a primary drawdown mechanism of atmospheric carbon dioxide. The processes that affect weathering are therefore central in controlling global climate. A temperature-controlled “weathering thermostat” has long been proposed in stabilising long-term climate, but without definitive evidence from the geologic record. […]

GPv6n1_100Future Global Mineral Resources
Nicholas T. Arndt, Lluís Fontboté, Jeffrey W. Hedenquist, Stephen E. Kesler, John F.H. Thompson and Daniel G. Wood

In this issue of Geochemical Perspectives, six authors with wide experience in ore deposit research, exploration and production present an optimistic but realistic appraisal of future mineral resources. They describe how ore deposits form, and how they are found, assessed, mined and processed. They discuss the critical differences between mineral reserves and resources, how economic and societal factors influence supply, and the critical roles that geoscientists will continue to play. The authors argue that mineral resources will remain adequate well into the future.
