Centre Européen de Recherche et d'Enseignement des Géosciences de l'Environnement) ; Zahn, Rainer (Cardiff University. Department of Earth Sciences)
Benthic Cd/Ca and δ13C records from the midlatitude and northern North Atlantic are used to derive nutrient inventories and water mass distribution patterns for the past 50,000 years. Inferred Holocene water column Cd concentrations (CdW') and δ13C values are 0. [...]

11 p, 456.0 KB Paleocurrent reconstruction of the deep Pacific inflow during the middle Miocene : reflections of East Antarctic Ice Sheet growth / Hall, Ian R. (Cardiff University. School of Earth and Ocean Sciences) ; McCave, I. Nicholas (University of Cambridge. Department of Earth Sciences) ; Zahn, Rainer (Universitat de Barcelona. Grup de Recerca Consolidat en Geociències Marines) ; Carter, Lionel (National Institute of Water and Atmosphere (Nova Zelanda)) ; Knutz, Paul C. (University of Copenhagen. Geological Institute) ; Weedon, Graham P. (University of Luton. Centre for Environmental Change and Volcanic Studies)
Today the deep western boundary current (DWBC) east of New Zealand is the most important route for deep water entering the Pacific Ocean. Large-scale changes in deep water circulation patterns are thought to have been associated with the development of the East Antarctic Ice Sheet (EAIS) close to the main source of bottom water for the DWBC.

14 p, 952.9 KB Deep water variability on the southern Agulhas Plateau: interhemispheric links over the past 170 ka / Molyneux, Elizabeth G. (Cardiff University. School of Earth, Ocean, and Planetary Sciences) ; Hall, Ian R. (Cardiff University. School of Earth, Ocean, and Planetary Sciences) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Diz, Paula (Cardiff University. School of Earth, Ocean, and Planetary Sciences)
Sortable silt mean grain sizes together with oxygen and carbon isotopic data produced on the benthic foraminiferal species Fontbotia wuellerstorfi are used to construct high-resolution records of near-bottom flow vigour and deep water ventilation at a core site MD02-2589 located at 2660 m water depth on the southern Agulhas Plateau.

14 p, 875.1 KB Centennial-scale variability of the British ice sheet: implications for climate forcing and Atlantic meridional overturning circulation during the last deglaciation / Knutz, Paul C. (University of Copenhagen. Geological Institute) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Hall, Ian R. (Cardiff University. School of Earth and Ocean Sciences)
Evidence from paleoclimatic archives suggests that Earth's climate experienced rapid temperature changes associated with pronounced interhemispheric asymmetry during the last glacial period. Explanations for these climate excursions have converged on nonlinear interactions between ice sheets and the ocean's thermohaline circulation, but the driving mechanism remains to be identified. [...]
