Abstract: Orbital tuning is central for ice core chronologies beyond annual layer counting, available back to 60 ka (i.e. thousands of years before 1950) for Greenland ice cores. While several complementary orbital tuning tools...
Abstract: Improving the representation of the hydrological cycle in atmospheric general circulation models (AGCMs) is one of the main challenges in modeling the Earth’s climate system. One way to evaluate model performance is to...
Abstract: The isotopic compositions of oxygen and hydrogen in ice cores are invaluable tools for the reconstruction of past climate variations. Used alone, they give insights into the variations of the local temperature, whereas...
Tree ring δ18O chronologies from two native species (Fitzroya cupressoides and Nothofagus pumilio) in northern Patagonia were developed to assess their potential for paleoclimate reconstructions.
The last interglacial period (LIG, ~129-116 thousand years ago) provides the most recent case study for multi-millennial polar warming above pre-industrial level and a respective response of the Greenland and Antarctic ice sheets to...
The periglacial features database can be found here.
Immigration and mobility in the mediaeval and post-mediaeval periods in Norway has, up until now, mainly been discussed on the basis of historical sources.
The isotopic composition of oxygen and deuterium in surface snow from East Antarctica varies primarily as a function of the local temperature. The snow that is deposited undergoes metamorphism (modification of grain shapes), as...
Climate reconstruction from ice cores rely on good knowledge of equilibrium and kinetic isotopic fractionation at each step of the water cycle. One of the strongest limitations when interpreting water isotopes in remote Antarctic...
The PAGES PALeo constraints on SEA level rise 2 (PALSEA2) working group organized their third workshop in July 22-24, 2015 (Atmosphere and Ocean Research Institute, University of Tokyo). This workshop aimed at integrating data...
The Last Interglacial (LIG) represents an invaluable case study to investigate the response of components of the Earth system to global warming. However, the scarcity of absolute age constraints in most archives leads to...
The next general assembly will take place on 7 december 2015 at 4:00pm in la Maison de la Géologie, Paris
The implementation of tritium in a GCM, and subsequent model-data comparison with a large available dataset, is a useful complement to the existing approach of using stable water isotope tracers. The method promises to...
The oldest ice core records are obtained on the East Antarctic plateau. The composition in stable isotopes of water (δ18O, δD, δ17O) permits to reconstruct the past climatic conditions over the ice sheet and...
In contrast to the East Asian and African monsoons the Indian monsoon is still poorly documented throughout the last climatic cycle (last 135,000 years). Pollen analysis from two marine sediment cores (NGHP-01-16A and NGHP-01-19B)...
