EAG Early Career Science Ambassador Program: deadline 1 March 2018

Ambass_100The Early Career Science Ambassador Program provides travel grants for Early Career Scientists based in Europe to attend conferences outside of Europe (except Goldschmidt conferences). Supported scientists will have 50 % of their expenses (up to 1500 euros) covered by EAG and be viewed as EAG Ambassadors while attending the event. The next deadline for applications is 1 March 2018. Details of how to apply can be found here

GPL1805 abstractThe xenon isotopic signature of the mantle beneath Massif Central
M. Moreira, V. Rouchon, E. Muller, S. Noirez

The origin of the Central European Volcanic Province, which includes the Massif Central and the Eifel regions, is currently debated. Several different causes have been proposed to account for the volcanism observed in the area. […]

GPL1804_abstractAtmospheric helium isotopic ratio from 1910 to 2016 recorded in stainless steel containers
C. Boucher, B. Marty, L. Zimmermann, R. Langenfelds

The atmospheric helium isotope composition (RA= 3He/4Heair = 1.39 × 10-6) could have varied over recent times due to anthropogenic activities. In order to check this possibility, we conducted high-precision helium isotope measurements of air trapped in various stainless steel containers from France (pétanque balls, a float carburettor; 1910–2016) and Cape Grim, Tasmania (archived air tanks; 1978, 1988). […]

GPL1803_abstractTh/U and U series systematics of saprolite: importance for the oceanic 234U excess
N. Suhr, M. Widdowson, F. McDermott, B.S. Kamber

The presence of excess 234U in seawater is a compelling argument for active delivery of solutes from the continents to the oceans. Previous studies found, however, that the complementary 234U deficit on the continents is surprisingly modest, which would require protracted U loss from a large continental weathering pool. […]

GPL1802 abstractNoble gases and nitrogen in Tissint reveal the composition of the Mars atmosphere
G. Avice, D.V. Bekaert, H. Chennaoui Aoudjehane, B. Marty

Comparative planetology is crucial to unravel the origin and evolution of volatile elements on terrestrial planets. We report precise measurements of the elemental and isotopic composition of nitrogen and noble gases in the Martian meteorite Tissint. […]

GeoPersp_v6n2_100Glacier Biogeochemistry
Martin Sharp, Martyn Tranter

This issue of Geochemical Perspectives charts a paradigm shift in glacier geochemistry and hydrochemistry. The beds of glaciers and ice sheets were thought to be abiotic only 20 years ago, but now it is known that a diverse range of microbes colonise these environments, and that microbial processes influence chemical weathering and nutrient cycling in aqueous subglacial environments.
