Journal ArticleDOI
A New Seismic Stratigraphy in the Indian-Atlantic Ocean Gateway Resembles Major Paleo-Oceanographic Changes of the Last 7 Ma
Jens Gruetzner,Francisco José Jiménez Espejo,Francisco José Jiménez Espejo,Nambiyathodi Lathika,Gabriele Uenzelmann-Neben,Ian Hall,Sidney R. Hemming,Leah J. LeVay +7 more
TL;DR: In this paper, the authors present results from International Ocean Discovery Program Site U1475 (Agulhas Plateau) located over a sediment drift proximal to the entrance of North Atlantic Deep Water into the Southern Ocean and South Indian Ocean.
Journal ArticleDOI

Journal ArticleDOI
Evidence for Extending Anomalous Miocene Volcanism at the Edge of the East Antarctic Craton.
Kathy J. Licht,T. Groth,Joshua P. Townsend,Andrea J. Hennessy,Sidney R. Hemming,T. P. Flood,Michael Studinger +6 more
TL;DR: Using field observations followed by petrological, geochemical, geochronological, and geophysical data, the authors infer the presence of a previously unknown Miocene subglacial volcanic center ~230 km from the South Pole.
Journal ArticleDOI
Pb isotope measurements of sanidine monitor standards: implications for provenance analysis and tephrochronology
TL;DR: Samples of Fish Canyon and Cobb Mountain sanidine monitor standards, irradiated and fused with 7 W of CO2 laser power for 40 Ar / 39 Ar geochronology analyses, give Pb isotope composition and Pb concentrations that are indistinguishable from unprocessed aliquots of the same monitors.
Journal ArticleDOI
Reconstruction of the Early Miocene Critical Zone at Loperot, Southwestern Turkana, Kenya
Cynthia M. Liutkus-Pierce,Kevin K. Takashita-Bynum,Luke Beane,Cole T. Edwards,Oliver E. Burns,Sara Mana,Sidney R. Hemming,Aryeh Grossman,James D. Wright,Francis Kirera +9 more
TL;DR: The authors reconstructs the early Miocene Critical Zone of Loperot to reveal a large perennial river system fed by ephemeral streams that created localized riparian forest microhabitats within a larger open ecosystem under semi-arid climate conditions.
