International audience; The Pliocene (5.33–2.58 Ma) was the last period in the Earth's history when atmospheric CO2 concentrations were similar to today (~400 ppm) and global mean temperatures were significantly warmer. In the Mediterranean, the Pl

The Ross Sea is one of the major sites of formation for Antarctic Bottom Water (AABW), a key component of the global ocean overturning circulation. However, there is currently a lack of high quality stratigraphic records documenting how this water ma

Obliquity pacing of Antarctic glaciations during the QuaternaryThe frequency of Antarctic glaciations during the Quaternary are not well understood. Benthic oxygen isotope records provide evidence for eccentricity paced global ice volume changes sinc

International audience; Over the last 5 million years, the Earth’s climate has oscillated between warm (interglacial) and cold (glacial) states. Some particularly warm interglacial periods (i.e. ‘super-interglacials’) occurred under low atmosph

Over the last 5 Million years, outstanding warm interglacial periods (i.e. ‘super-interglacials’) occurred under low atmospheric CO2 levels that may feature extensive Antarctica ice sheet collapse. Here, we focus on the extreme super-interglacial

Organic biomarkers, such as n-alkanes, can be used as proxies in a range of paleoclimate and paleoenvironmental investigations. n-Alkanes accumulate in lacustrine sediments and can therefore be used to determine past terrestrial conditions by investi

We present alkenone-derived sea surface temperature (SST) records from the New Zealand/Tasmania sector of the Southern Ocean (ODP Sites 1171 and 1125) during the Early Pleistocene (c. 1.7 to 0.7 Ma). Our data show that the subantarctic surface waters

The response of the Antarctic ice sheets to future warming is uncertain. The IPCC are predicting minimal melt from Antarctica while others suggest increased meltwater contributions are possible. The Pliocene period (5.333 Ma to 2.58 Ma) may provide i

Carbonate fractions of pelagic and hemipelagic sediments may contain significant proportions of microcrystalline (≤ 6 µm) calcitic particles with no specific structure so-called micarb. Depending on the authors, this term is related to different d
