Geochimica et Cosmochimica Acta, 67(12), 2157-2171

Radiocarbon stratigraphy is an essential tool for high resolution paleoceanographic studies. Age models based on radiocarbon ages of foraminifera are commonly applied to a wide range of geochemical studies, including the investigation of temporal leads and lags. The critical assumption is that temporal coupling between foraminifera and other sediment constituents, including specific molecular organic compounds (biomarkers) of marine phytoplankton, e.g. alkenones, is maintained in the sediments.To test this critical assumption in the Benguela upwelling area,...

(Table 1) Body condition and plasma POP concentrations of glaucous gulls from Bjørnøya, Svalbard archipelago, supplement to: Verboven, Nanette; Verreault, Jonathan; Letcher, Robert J; Gabrielsen, Geir W; Evans, Neil P (2009): Nest temperature and parental behaviour of Arctic-breeding glaucous gulls exposed to persistent organic pollutants. Animal Behaviour, 77(2), 411-418

Nanette Verboven, Jonathan Verreault, Robert J Letcher, Geir W Gabrielsen & Neil P Evans
Behavioural field observations are increasingly being used in ecotoxicological research to identify potential adverse effects of exposure to persistent organic pollutants (POPs). We investigated thermal conditions inside the nest and parental behaviour of glaucous gulls, Larus hyperboreus, breeding in the Norwegian Arctic in relation to the concentrations of major classes of POPs (organochlorines, brominated flame retardants and metabolically derived products) accumulated in their blood. Most notably, nest temperature was negatively correlated with the concentrations of...

Stable isotope data of sediment cores in the western equatorial Atlantic, supplement to: Dürkoop, Anke; Hale, Walter; Mulitza, Stefan; Pätzold, Jürgen; Wefer, Gerold (1997): Late Quaternary variations of sea surface salinity and temperature in the western tropical Atlantic: Evidence from d18O of Globigerinoides sacculifer. Paleoceanography, 12(6), 764-772

Anke Dürkoop, Walter Hale, Stefan Mulitza, Jürgen Pätzold & Gerold Wefer
In order to reconstruct hydrographic changes during glacial-interglacial cycles for a transequatorial transect we analyzed oxygen isotopes of Globigerinoides sacculifer (without sac-like chamber) and abundances of Globorotalia truncatulinoides (dextral) from FS Meteor cores GeoB 2204-2 (Brazilian continental slope) and GeoB 1523-1 (Ceara Rise). Delta d18O values of G. sacculifer between the two cores were calculated. Modern Delta d18O (G. sacculifer) is ~0.2 per mill between the two core positions, reflecting differences in sea surface salinity...

Planktonic Mg/Ca and stable oxygen isotope ratios for DSDP Hole 90-590B, supplement to: Karas, Cyrus; Nürnberg, Dirk; Tiedemann, Ralf; Garbe-Schönberg, Carl-Dieter (2011): Pliocene climate change of the Southwest Pacific and the impact of ocean gateways. Earth and Planetary Science Letters, 301(1-2), 117-124

Cyrus Karas, Dirk Nürnberg, Ralf Tiedemann & Carl-Dieter Garbe-Schönberg
The transition from the early Pliocene "Warmhouse" towards the present "Icehouse" climate and the role of Gateway dynamics are intensively debated. Both, the constrictions of the Central American Seaway and the Indonesian Gateway affected ocean circulation and climate during the Pliocene epoch. Here, we use combined d18O and Mg/Ca ratios of planktonic foraminifera (marine protozoa) from surface and subsurface levels to reconstruct the thermal structure and changes in salinities from the Southwest Pacific Deep Sea...

This study presents a newly compiled dataset of modern pollen and climate data from 798 sites across Japan and the Russian Far East. This comprehensive reference dataset combined with the modern analogue technique (MAT) provides a powerful tool for pollen-based reconstruction of the Quaternary Northwest Pacific climate. Pollen-derived reconstruction of the modern climate at the reference pollen-sampling sites matches well with the estimated modern climate values (R2 values vary between 0.79 and 0.95, and RMSEP...

Benthic foraminiferal δ¹⁸O and Mg/Ca studies of sediment cores off tropical NW Africa, supplement to: Huang, Enqing; Mulitza, Stefan; Paul, André; Groeneveld, Jeroen; Steinke, Stephan; Schulz, Michael (2012): Response of eastern tropical Atlantic central waters to Atlantic meridional overturning circulation changes during the Last Glacial Maximum and Heinrich Stadial 1. Paleoceanography, 27

Enqing Huang, Stefan Mulitza, André Paul, Jeroen Groeneveld, Stephan Steinke & Michael Schulz
Benthic foraminiferal d18O and Mg/Ca of sediment cores off tropical NW Africa are used to study the properties of Atlantic central waters during the Last Glacial Maximum (LGM) and Heinrich Stadial 1 (HS1). We combined our core top data with published results to develop a new Mg/Ca-temperature calibration for Planulina ariminensis, which shows a Mg/Ca-temperature sensitivity of 0.19 mmol/mol per °C. Estimates of the LGM and HS1 thermocline temperatures are comparable to the present-day values...
