Steppes Secrètes A travers les paysages du Kazakhstan, de l’Ouzbékistan, de la Mongolie et de la Chine, il vous offre une sélection de plus de 200 photographies documentaires de nature et de voyage, commentées par nombre d’anecdotes naturalistes.

2021-07-01. Terra Antiqua plugin officially released

Terra Antiqua is a plug in for QGIS ( install QGIS) we developed to make paleogeographic reconstructions.

The plugin can then be installed directly from QGIS (Plugins/ Manage and Install Plugins)

2021-03-02. The onset of Asian dust

The retreat of the proto-Paratethys Sea resulted in aridification and the onset of a high-pressure system over Siberia driving the East Asian winter monsoon and dust storms.

Enjoy Niel’s cutting edge thesis work including the age of the onset of Asian dust production, a new hypothesis for this dust generation and a reappraisal of grain size methods for dust interpretations. See also Niel’s great review on interpreting dust in the sedimentary record.

2020-12-09. Chronology of the Tibetan Plateau uplift

The topographic evolution of the Tibetan Plateau is essential for understanding its construction and its influences on climate, environment, and biodiversity. The timing of uplift is a hugely controversial topic that is resolved in our recent paper:
