15-10-2013: New publication: Northern and southern hemisphere controls on seasonal sea surfac temperatures in the Indian Ocean during the last deglaciation

Yiming Wang, Guillaume Leduc, Marcus Regenberg, Nils Andersen, Thomas Larsen, Thomas Blanz, and Ralph Schneider present in a publication in Paleoceanograpy reconstructions of two commonly used paleothermometers (the foraminifera G. ruber Mg/Ca and the alkenone unsaturation index) from a marine sediment core collected in the southwestern tropical Indian Ocean encompassing the last 37,000 years.

Their study reveals that the tropical southwestern Indian Ocean seasonal SST was closely linked to climate changes occurring in both hemispheres. The austral summer and winter recorded by each proxy is further supported with seasonal SST trends modeled by Atmosphere–Ocean General Circulation Models for our core site. Our interpretation that the alkenone and Mg/Ca SSTs are seasonally biased may also explain similar proxy mismatches observed in other tropical regions at the onset of the last termination.

31-07-2013: New publication: Rainfall response to orbital and millennial forcing in northern Peru over the last 18 ka

Elfi Mollier-Vogel, Guillaume Leduc, Tebke Bösche, Philippe Martinez, Ralph Schneider present in a publication in Quaternary Science Reviews new views of rainfall response to orbital and millennial forcing in the northern Peru over the last 18 ka

  • We present high-resolution XRF measurements from the Guayas River mouth, Ecuador
  • We record changes in riverine runoff associated with rainfall during the last 18 ka BP
  • Wetter conditions occurred during late Holocene and H1 as compared to mid-Holocene
  • Millennial-scale latitudinal shifts of ITCZ show North–South antiphase in rainfall changes above South America
  • An East–West rainfall antiphase at equatorial latitudes above South America at orbital-scale may result from monsoon intensity changes

27-06-2013 Welcome, Antje

The working group Marine Climate Research welcomes Antje Wildau, who joined as a PhD Student the working group "Paleooceanography and -climate" (Prof. Ralph Schneider) on May 27th. Antje will work on the project "Geochemical paleoproxies of the Arctic" which is part of the international and interdisciplinary research project "The Transpolar System of the Arctic Ocean".
Previously, she worked at the McGill University, Canada. During the last three years, she investigated the mineralogy and geochemistry of the Bon Accord Ni-oxide body in Barberton, South Africa; Antje also cooperated on a research project about the characterization of hydrothermal fluids in the Witwatersrand, South Africa, but also on a geochemical study about the occurrence of dendritic Cr-rich magnetite in forsteritic olivine from the Kondyor massif, Russia, and the Driekop mine, South Africa. She gained her MSc from the University of the Free State, South Africa.


05-04-2013 Welcome, Xu

The working group Marine Climate Research welcomes Dr. Xu Xu, who joined as a postdoc the working group "Paleoclimate Modeling" (Prof.Birgit Schneider) on March 1st.

She will work on the project "Simulating tropical marine climate-biogeochemical interactions from the Holocene into the Anthropocene". She previously worked at the Alfred Wegener Institute.

During the last three and half years, she simulated the oceanic and foraminiferal oxygen isotope variations at the present day and the Last Glacial Maximum. She gained her PhD from Bremen University.The working group Marine Climate Research welcomes Dr. Xu Xu, who joined as a postdoc the working group "Paleoclimate Modeling" (Prof.Birgit Schneider) on March 1st.

15-02-2013: New publication: Peak glacial 14C ventilation ages suggest major draw-down of carbon into the abyssal ocean

Michael Sarnthein, Birgit Schneider and P. M. Grootes present in a publication in Climate of the Past Discussions (CPD) a new ocean-wide 14C dataset showing that during the Last Glacial Maximum (LGM) and Heinrich Stadial 1 (HS-1) the 14C age difference between ocean deep waters and the atmosphere exceeded the modern values by up to 1500 14C yr. From the extrapolation of the modern relationship between dissolved inorganic carbon (DIC) and 14C, they infer that the deep ocean was indeed able to accomodate an additional amount of 730-980 GtC during glacial times, which contributes to a long lasting scientific debate.
