10 p, 825.3 KB Exceptional Agulhas leakage prolonged interglacial warmth during MIS 11c in Europe / Koutsodendris, Andreas (Universität Heidelberg. Institut für Geowissenschaften) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Pross, Jörg (Universität Heidelberg. Institut für Geowissenschaften)
The transport of warm and saline surface water from the Indo-Pacific Ocean into the South Atlantic ("Agulhas leakage") influences the Atlantic Meridional Overturning Circulation (AMOC), which in turn exerts control on European climate. [...]

11 p, 804.1 KB Seasonal patterns of shell flux, δ18O and δ13C of small and large N. pachyderma (s) and G. bulloides in the subpolar North Atlantic / Jonkers, Lukas (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Heuven, Steven van (Cardiff University. School of Earth and Ocean Sciences) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Peeters, Frank J. C. (Vrije Universiteit Amsterdam)
Past water column stratification can be assessed through comparison of the δ18O of different planktonic foraminiferal species. The underlying assumption is that different species form their shells simultaneously, but at different depths in the water column. [...]

10 p, 993.6 KB Three hundred eighty thousand year long stable isotope and faunal records from the Red Sea : influence of global sea level change on hydrography / Hemleben, Christoph (University of Tübingen. Institute and Museum for Geology and Paleontology) ; Meischner, Dieter (University of Göttingen. Institute for Geology and Paleontology) ; Zahn, Rainer (GEOMAR Research Center for Marine Geosciences (Alemanya)) ; Almogi-Labin, Ahuva (Geological Survey of Israel) ; Erlenkeuser, Helmut (Institut für Reine und Angewandte Kernphysik (Alemanya)) ; Hiller, Birgit (University of Tübingen. Institute and Museum for Geology and Paleontology)
Stable isotope and faunal records from the central Red Sea show high-amplitude oscillations for the past 380,000 years. Positive δ18O anomalies indicate periods of significant salt buildup during periods of lowered sea level when water mass exchange with the Arabian Sea was reduced due to a reduced geometry of the Bab el Mandeb Strait.

15 p, 1.2 MB Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle / Mortyn, P. Graham (University of South Carolina. Department of Geological Sciences) ; Thunell, Robert C. (University of South Carolina. Department of Geological Sciences) ; Anderson, David M. (NOAA Paleoclimatology Program (Boulder, Colorado)) ; Stott, Lowell D. (University of South Carolina. Department of Earth Sciences) ; Le, Jianning (University of South Carolina. Department of Geological Sciences)
A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene. Planktonic foraminiferal δ18O evidence and average SST estimates derived by the modern analog technique indicate that temperatures were 6°-10°C cooler during the last glacial relative to the present.

15 p, 1.8 MB Thermohaline instability in the North Atlantic during meltwater events: Stable isotope and ice-rafted detritus records from Core SO75-26KL, Portuguese Margin / Zahn, Rainer (GEOMAR Research Center for Marine Geosciences) ; Schönfeld, Joachim (GEOMAR Research Center for Marine Geosciences) ; Kudrass, Hermann-Rudolf (Bundesanstalt fiir Geowissenschaften und Rohstoffe (Alemanya)) ; Park, Myong-Ho (GEOMAR Research Center for Marine Geosciences) ; Erlenkeuser, Helmut (Christian-Albrechts-Universität zu Kiel (Alemanya)) ; Grootes, Pieter (Christian-Albrechts-Universität zu Kiel (Alemanya))
A benthic isotope record has been measured for core SO75-26KL from the upper Portuguese margin (1099 m water depth) to monitor the response of thermohaline overturn in the North Atlantic during Heinrich events. [...]

10 p, 1.2 MB Interhemispheric appraisal of the value of alkenone indices as temperature and salinity proxies in high-latitude locations / Rosell Melé, Antoni (University of Newcastle. Department of Fossil Fuels and Environmental Geochemistry)
Alkenone sediment data from the Nordic seas and North Atlantic are compared to those from Sikes et al. [1997] for the Southern Ocean to evaluate further UK37 and UK37' as proxies to estimate cold temperatures (<10°C) and the effect of salinity and temperature in the relative abundance of 37∶4 to the total abundance of C37 alkenones (37∶4%).

7 p, 959.7 KB Evidence for a Warm Last Glacial Maximum in the Nordic Seas or an example of shortcomings in UK37' and UK37 to estimate low sea surface temperature? / Rosell Melé, Antoni (University of Newcastle. Department of Fossil Fuels and Environmental Geochemistry) ; Comes, Pau (University of Durham. Department of Geography)
The occurrence of ice-free conditions in the Nordic seas during the Last Glacial Maximum has been demonstrated using microfossil and biomarker approaches. An accurate picture of the prevailing oceanographic conditions may be more difficult to ascertain. [...]

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. [...]
