High precision measurements of triple isotopic composition of oxygen in the air trapped in ice cores is a useful tool to infer the global gross biosphere productivity in the past. The isotopic composition of oxygen is influenced by many physical, che

By diffusing from the sediments into the ocean, 227Ac (half-life = 21.8 y) is a powerful tracer of vertical mixing in the deep ocean on decadal time scales. However, its use is limited by its very low concentration resulting in large volumes (hundred

Owing to their inertness and contrasted composition in the various earth reservoirs, helium isotopes are powerful tracers of a number of processes pertaining to geophysics and geochemistry. Because sediments cover a large portion of the earth's surfa

Hydrothermal vent fields south of the Garret Fracture zone were sampled for the isotope composition of helium and oxygen ([18O]H2O/[16OH2O). The helium isotopes end-member (3He / 4He=8.3×R a and [4He]≈1.2–2.4×10-5 cm3 STP g-1) is quite similar

International audience; Hydrothermal fluids were sampled for dissolved gases at TAG (26øN-MAR) during two Alvin dive series, in April-May 1993 and March 1995, respectively 17 months before and 4 months after Ocean Drilling Program Leg 158. Total gas
