Paleotemperature reconstruction for the past 0.55 Ma of the Subantarctic zone

Estimates of summer sea surface temperatures (SSSTs) derived from planktic foraminiferal associations using the Modern Analog Technique and combined with isotopic analyses and...

Radionuclides in sediment cores of the Atlantic sector of the Southern Ocean

We present time series of export productivity proxy data including 230Thex-normalized deposition rates (rain rates) of 10Be, dissolution-corrected biogenic Ba, and biogenic opal...

Petrology, geochemistry and K-Ar Age determination of De Gerlache Seamount ba...

The De Gerlache Seamounts are two topographic highs in the Bellingshausen Sea, southeastern Pacific. Petrological and geochemical studies together with K-Ar age determinations...

Particle fluxes and composition at two mooring sites in the Polar Front Region

Particle fluxes and composition were examined over 5 years at two mooring sites in the Polar Front Region (site PF: 50°09.S, 5°50.E) and in the marginal winter sea-ice zone...

Stabile Isotope aus Sedimenten des Spätquartär vom Atlantisch-Indischen Rücke...

Sedimentology and stable isotope measurements on sediment cores from the Atlantic-Indian Ridge.

Palaeoceanographic data of sediment core MD01-2416

We present an SiF4 separation line, coupled to a laser fluorination system, which allows for an efficient combined silica d18O and d30Si analysis (50 min per sample). The...

Dust flux records from the Subarctic North Pacific

We present a new record of eolian dust flux to the western Subarctic North Pacific (SNP) covering the past 27000 years based on a core from the Detroit Seamount. Comparing the...

Age models and summer sea surface temperature and winter sea ice concentratio...

Sea surface temperatures and sea-ice extent are the most critical variables to evaluate the Southern Ocean paleoceanographic evolution in relation to the development of the...

The seasonal sea-ice zone in the glacial Southern Ocean as a carbon sink, sup...

Reduced surface-deep ocean exchange and enhanced nutrient consumption by phytoplankton in the Southern Ocean have been linked to lower glacial atmospheric CO2. However,...

Stable isotope records and biogenic barium fluxes of sediment core SO202-07-06

Reduced nitrate supply to the subarctic North Pacific (SNP) surface during the last ice age has been inferred from coupled changes in diatom-bound d15N (DB-d15N), bulk...

Neodymium isotope data from South Pacific sediment cores

Stratification of the deep Southern Ocean during the Last Glacial Maximum is thought to have facilitated carbon storage and subsequent release during the deglaciation as...

Diatoms abundance in sediment core of the Pacific sector of the Southern Ocean

The last transition from a full glacial to a full interglacial state is of special importance to investigate processes that control the Earth's climate evolution. Out of phase...
