Stable oxygen isotope data of Globigerinoides ruber white and titanium intensity from sediment core GeoB6211-2, supplement to: Chiessi, Cristiano Mazur; Mulitza, Stefan; Pätzold, Jürgen; Wefer, Gerold; Marengo, José A (2009): Possible impact of the Atlantic Multidecadal Oscillation on the South American summer monsoon. Geophysical Research Letters, 36, L21707

Cristiano Mazur Chiessi, Stefan Mulitza, Jürgen Pätzold, Gerold Wefer & José A Marengo
The South American summer monsoon (SASM) is the main source of precipitation for the most densely populated and agriculturally productive regions of tropical and subtropical South America. Here we investigate the impact of the Atlantic Multidecadal Oscillation (AMO) on the SASM using ~4500 yr long proxy records of the discharge variability of the La Plata River Drainage Basin (PRDB), subtropical South America. We measured the stable oxygen composition of planktic foraminifera (related to the extension...

Sedimentology and planktonioc foraminifera of core SU90-08, supplement to: Grousset, Francis E; Labeyrie, Laurent D; Sinko, J A; Cremer, Michel; Bond, Gerard C; Duprat, Josette M; Cortijo, Elsa; Huon, Sylvain (1993): Patterns of ice-rafted detritus in the glacial North Atlantic. Paleoceanography, 8(2), 175-192

Francis E Grousset, Laurent D Labeyrie, J A Sinko, Michel Cremer, Gerard C Bond, Josette M Duprat, Elsa Cortijo & Sylvain Huon
The observation by Heinrich (1988) that, during the last glacial period, much of the input of ice-rafted detritus to the North Atlantic sediments may have occurred as a succession of catastrophic events, rekindled interest on the history of the northern ice sheets over the last glacial period. In this paper, we present a rapid method to study the distribution of these events (both in space and time) using whole core low-field magnetic susceptibility. We report...

Age determination and radionuclides of sediment cores from the Western Atlantic, supplement to: Broecker, Wallace S; Lao, Yong; Klas, Mieczyslawa; Clark, Elizabeth; Bonani, Georges; Ivy, Susan; Chen, Chin (1993): A search for an early Holocene CaCO3 preservation event. Paleoceanography, 8(3), 333-339

Wallace S Broecker, Yong Lao, Mieczyslawa Klas, Elizabeth Clark, Georges Bonani, Susan Ivy & Chin Chen
The CO2 record for air bubbles from the Byrd Station ice core suggest a drawdown in the ocean-atmosphere carbon reservoir during the early Holocene. Such a drawdown would require a corresponding increase in the CO3= ion concentration in the deep sea. We report here the results of a search in Atlantic sediments for evidence that the lysocline showed a corresponding deepening. While both the pteropod and the calcite preservation records we have obtained are consistent...

Cenozoic record of continental mineral deposit on Broken and Ninetyeast Ridges, Indian Ocean, supplement to: Hovan, Steven A; Rea, David K (1992): The Cenozoic record of continental mineral deposition on Broken and Ninetyeast Ridges, Indian Ocean: Southern African aridity and sediment delivery from the Himalayas. Paleoceanography, 7(6), 833-860

Steven A Hovan & David K Rea
The mineral component of pelagic sediments recovered from the Indian Ocean provides both a history of eolian deposition related to climatic changes in southern Africa and a record of terrigenous input related to sediment delivery from the Himalayas. A composite Cenozoic dust flux record from four sites in the central Indian Ocean is used to define the evolution of the Kalahari and Namib desert source regions. The overall record of dust input is one of...

Clay mineralogy and organic carbon content of sediment core GeoB1401-4, supplement to: Gingele, Franz; Müller, Peter J; Schneider, Ralph R (1998): Orbital forcing of freshwater input in the Zaire area - clay mineral evidence from the last 200 kyr. Palaeogeography, Palaeoclimatology, Palaeoecology, 138(1-4), 17-26

Franz Gingele, Peter J Müller & Ralph R Schneider
Late Quaternary sediments recovered in a core from the area of the Zaire Fan, Central Africa, were analyzed for clay mineral composition in order to reconstruct fluctuations in the sediment input and freshwater discharge of the Zaire River. Clay mineral assemblages are dominated by kaolinite and smectite, which both originate mainly from the Zaire River and contain only minor contributions of eolian dust. Smectite crystallinity and chemical character of illites (Fe, Mg- or Al-rich) are...

Physical properties and age determination of sediment cores from the Hinlopen/Yermak Megaslide north of Spitsbergen, Arctic Ocean, supplement to: Winkelmann, Daniel; Geissler, Wolfram H; Schneider, Julia; Stein, Ruediger (2008): Dynamic and timing of the Hinlopen/Yermak Megaslide north of Spitsbergen, Arctic Ocean. Marine Geology, 250(1-2), 34-50

Daniel Winkelmann, Wolfram H Geissler, Julia Schneider, Ruediger Stein & Hans Werner Schenke
Integrated interpretation of multi-beam bathymetric, sediment-penetrating acoustic (PARASOUND) and seismic data show a multiple slope failure on the northern European continental margin, north of Spitsbergen. The first slide event occurred during MIS 3 around 30 cal. ka BP and was characterised by highly dynamic and rapid evacuation of ca. 1250 km**3 of sediment from the lower to the upper part of the continental slope. During this event, headwalls up to 1600 m high were created...

Recent benthic foraminifera of the Scotia Sea and Argentine Basin, supplement to: Harloff, Joachim; Mackensen, Andreas (1997): Recent benthic foraminiferal associations and ecology of the Scotia Sea and Argentine Basin. Marine Micropaleontology, 31(1-2), 1-29

Joachim Harloff & Andreas Mackensen
We investigated 88 surface sediment samples taken with a multiple corer from the southwestern South Atlantic Ocean for their live (Rose Bengal stained) and dead benthic foraminiferal content. Using Q-Mode Principal Component Analysis six live and six dead associations are differentiated. Live and dead association distributions correspond fairly well; differences are mainly caused by downslope transport and selective test destruction. In addition, four potential fossil associations are calculated from the dead data set after removal...

Automated Tools for Layer Recognition (BMPix) and Counting (PEAK), supplement to: Weber, Michael E; Reichelt, Lucia; Kuhn, Gerhard; Pfeiffer, Miriam; Korff, Björn; Thurow, Juergen W; Ricken, Werner (2010): BMPix and PEAK tools: New methods for automated laminae recognition and counting-Application to glacial varves from Antarctic marine sediment. Geochemistry, Geophysics, Geosystems, 11(3), Q0AA05

Michael E Weber, Lucia Reichelt, Gerhard Kuhn, Miriam Pfeiffer, Björn Korff, Juergen W Thurow & Werner Ricken
We present tools for rapid and quantitative detection of sediment lamination. The BMPix tool extracts color and gray-scale curves from images at pixel resolution. The PEAK tool uses the gray-scale curve and performs, for the first time, fully automated counting of laminae based on three methods. The maximum count algorithm counts every bright peak of a couplet of two laminae (annual resolution) in a smoothed curve. The zero-crossing algorithm counts every positive and negative halfway-passage...

Physical oceanography from 120 CTDs, 79 water bottles stations, and 30 helicopter-borne CTDs during POLARSTERN cruise ANT-XXII/2 (ISPOL), supplement to: Absy, Joao Marcelo; Schröder, Michael; Muench, Robin D; Hellmer, Hartmut H (2008): Early summer thermohaline characteristics and mixing in the western Weddell Sea. Deep Sea Research Part II: Topical Studies in Oceanography, 55(8-9), 1117-1131

Joao Marcelo Absy, Michael Schröder, Robin D Muench & Hartmut H Hellmer
The Ice Station POLarstern (ISPOL) cruise revisited the western Weddell Sea in late 2004 and obtained a comprehensive set of conductivity-temperature-depth (CTD) data. This study describes the thermohaline structure and diapycnal mixing environment observed in 2004 and compares them with conditions observed more than a decade earlier. Hydrographic conditions on the central western Weddell Sea continental slope, off Larsen C Ice Shelf, in late winter/early spring of 2004/2005 can be described as a well-stratified environment...
