We present high-resolution benthic δ13C records from intermediate water depth core site MD01-2461 (1153 m water depth), from the Porcupine Seabight, NE Atlantic, spanning 43 to 8 kyr B. P. At an average proxy time step of 160 ± 56 years this core provides information on the linkage between records from the Portuguese Margin and high-latitude North Atlantic basin, allowing additional insights into North Atlantic thermohaline circulation (THC) variability during millennial-scale climatic events of the last glacial.

(University of Minnesota. Department of Geology and Geophysics)
Abrupt decreases of the Atlantic meridional overturning circulation (MOC) during the Late Pleistocene have been directly linked to catastrophic discharges of glacimarine freshwater, triggering disruption of northward marine heat transport and causing global climate changes. [...]

15 p, 1022.8 KB High-latitude forcing of diatom productivity in the southern Agulhas Plateau during the past 350 kyr / Romero, O. E. (MARUM Center for Marine Environmental Sciences) ; Kim, J. H.

School of Earth and Ocean Sciences) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Schneider, R. (Universität Kiel. Institut für Geowissenschaften)
The hydrography of the Indian-Atlantic Ocean gateway has been connected to high-latitude climate dynamics by oceanic and atmospheric teleconnections on orbital and suborbital timescales. A wealth of sedimentary records aiming at reconstructing the late Pleistocene paleoceanography around the southern African continent has been devoted to understanding these linkages. [...]

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.

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, 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.
