Instabilité climatique, variations du niveau de la mer et géomorphologie au cours du dernier interglaciaire et de la dernière glaciation : état de la question / Climatic instability, sea-level changes and geomorphology during the last interglacial and the last glacial periods: a review

Abstract

Abstract Millennial-scale climatic oscillations (frequency # 1,5 ka) occurring during the last glacial and interglacial periods have been detected from high-resolution records in ice cores and marine or continental sediments. These results are compared with those which aim to identify sea-level changes during the same period. Better than the eustatic curves deduced from marine oxygen isotope records, the geo- morphological study of raised marine terraces, in highly uplifted areas, gives evidence that the periodicity (up to 2,8 ka) of sea-level changes is approximately in phase with climatic variations since 128 ka.
