    Noble gas concentrations of oceanic crust and sediments from the Ninety East Ridge in the Indian Ocean
    PANGAEA
    In:  Supplement to: Staudacher, Thomas; Allègre, Claude J (1988): Recycling of oceanic crust and sediments: the noble gas subduction barrier. Earth and Planetary Science Letters, 89(2), 173-183, https://doi.org/10.1016/0012-821X(88)90170-7

    Description: We have determined the concentrations and isotopic composition of noble gases in old oceanic crust and oceanic sediments and the isotopic composition of noble gases in emanations from subduction volcanoes. Comparison with the noble gas signature of the upper mantle and a simple model allow us to conclude that at least 98% of the noble gases and water in the subducted slab returns back into the atmosphere through subduction volcanism before they can be admixed into the earth's mantle. It seems that the upper mantle is inaccessible to atmospheric noble gases due to an efficient subduction barrier for volatiles.

    Neodymium isotope record of the past 25 Ma in the Indian Ocean (2008)
    PANGAEA
    In:  Supplement to: Gourlan, Alexandra T; Meynadier, Laure M; Allègre, Claude J (2008): Tectonically driven changes in the Indian Ocean circulation over the last 25 Ma: Neodymium isotope evidence. Earth and Planetary Science Letters, 267(1-2), 353-364, https://doi.org/10.1016/j.epsl.2007.11.054

    Description: Changes in ancient oceanic current patterns have been strongly influenced by plate tectonics, particularly by the opening or closing of gateways between different oceans. Such modifications of oceanic circulation have important consequences on climate. We studied the Nd seawater isotopic composition of Indian and Pacific Ocean cores using Nd isotopes, which are good paleo-oceanographic tracers. We focused on the past 25 Ma which are marked by the closure of the Indonesian gateway as well as the Mediterranean connection. We show that a strong westerly oceanic surface current, which we refer to the Miocene Indian Ocean Equatorial Jet (MIOJet), linked the eastern and western Indian Ocean from 14 Ma to 3 Ma and infer that this major change in oceanic circulation probably induced important variations of global climate.
