Geochemical and physical sediment properties of sediment cores from the Portuguese shelf (2009)

Alt-Epping, Ulrich, Stuut, Jan-Berend, Hebbeln, Dierk, Schneider, Ralph

Marine sediments from the Portuguese shelf are influenced by environmental changes in the surrounding continental and marine environment. These are largely controlled by the North Atlantic...

Distribution of surface sediment properties along the Portuguese western margin (2009)

Alt-Epping, Ulrich, Mil-Homens, Mário, Hebbeln, Dierk, Abrantes, Fatima, Schneider, Ralph

Organic matter contained in surface sediments from four regions on the western Portuguese shelf, which are influenced by coastal upwelling and fluvial input, was analysed with respect to elemental...

(Table 1) Age model for ODP Site 175-1077 based on oxygen isotopes of Globigerinoides ruber pink (2009)

Dupont, Lydie M, Donner, Barbara, Schneider, Ralph, Wefer, Gerold

Palynological records from the Congo fan reveal environmental change in equatorial Africa occurring 1.05 Ma ago, 100 k.y. before the mid-Pleistocene climatic shift at 0.9 Ma. Prior to 1.05 Ma, a...

A Tropical Mechanism for Northern Hemisphere (2007)

Keith B. Rodgers, Gerrit Lohmann, Stephan Lorenz, Ralph Schneider, Gideon M. Henderson

Abstract. We investigate the role of the tropics in the melting and reforming of the Laurentide ice sheet on glacial timescales using an atmospheric general circulation model. It is found that...

Pleistocene sedimentation in the Benguela Current, southeastern Atlantic (2003)

Jahn, Britta, Donner, Barbara, Müller, Peter J, Röhl, Ursula, Schneider, Ralph, Wefer, Gerold

We infer variations in paleoproductivity and eolian input at ODP Site 1082 in the Walvis Basin from stable oxygen isotope compositions of the planktonic foraminifera Globorotalia inflata, total...

Tool support for the management of design processes in chemical engineering (2003)

Manfred Nagl, Bernhard Westfechtel, Ralph Schneider

Design processes in chemical engineering are hard to support. In particular, this applies to conceptual design and basic engineering, in which the fundamental decisions concerning the plant design...

Planktonic foraminifera of sediment core T89-40 on the Walvis Ridge, South Atlantic (2000)

Ufkes, Els, Jansen, J H Fred, Schneider, Ralph

Core T89-40, eastern Walvis Ridge between the subtropical gyre and Benguela coastal upwelling system, contains three types of levels of abundant left-coiled Neogloboquadrina pachyderma, a cold,...

Abundance of calcareous dinoflagellates of sediment cores from the South Atlantic Ocean (2000)

Esper, Oliver, Zonneveld, Karin A F, Höll, Christine, Karwath, Britta, Schneider, Ralph, Vink, Annemiek, ...

Despite the increasing interest in the South Atlantic Ocean as a key area of the heat exchange between the southern and the northern hemisphere, information about its palaeoceanographic conditions...

Sea surface temperatures derived from alkenones from Late Quaternary sediments of the East Equatorial South Atlantic (1995)

Schneider, Ralph, Müller, Peter J, Ruhland, Götz

Angola Basin and Walvis Ridge records of past sea surface temperatures (SST) derived from the alkenone Uk 37 index are used to reconstruct the surface circulation in the east equatorial South...
