River deltas are dynamic costal systems and their evolutions are closely monitored as it often concentrates vital natural resources for the surrounding areas. Many deltas, worldwide, experience subsidence due to geological processes (sediment loading and compaction) or human activities (groundwater or hydrocarbon extraction, land reclamation). This...

Time-series bathymetric data acquired from 1967 to 2011 are used to evaluate the morphological evolution of the continental shelf and upper continental slope off the city of Nice (SE France, Ligurian Sea). Mapping in water depths of 0–300 m was undertaken to identify the changing morphology of landslide scars and their erosive chutes. Quantitative...

Les glissements de terrains sous-marins, même de petite taille, représentent un risque majeur d’érosion littorale et de submersion marine lorsqu’ils sont déclenchés à proximité des côtes. Ce fut le cas à Nice (France) avec l’effondrement en mer d’une partie de la plateforme aéroportuaire, suivit d’un tsunami du fait d’un glissement sous-marin en oc...

North Africa is the largest source of mineral dust on Earth, which has multiple impacts on the climate system; however, our understanding of decadal to centennial changes in African dust emissions over the last few millennia is limited. Here, we present a high-resolution multiproxy analysis of sediment core from high-elevation lake Bastani, in Cors...

Time-series bathymetric data acquired between 1991 and 2011 have been used to evaluate the recent morphological evolution of the Nice upper continental slope (SE France, Ligurian Sea). Small-scale landslides lead to a retrogressive evolution of the continental shelf/upper slope transition but their frequency, size and impact are not well known. Map...

Here, we present a high-resolution multiproxy analysis of sediment core from high-elevation Lake Bastani, on th...
