GM5.3 | Source-to-sink : From continental surface processes to deep marine depocenters
Source-to-sink : From continental surface processes to deep marine depocenters
Convener: Etienne Large | Co-conveners: Sophie Hage, Mara Limonta, William Rapuc
Source-to-sink studies have always been of utmost importance in Geosciences. They investigate how and at what rate sediments travel from continental erosional to marine depositional environments. These studies aim to understand, quantify and monitor over time, the processes responsible for sediment formation, transport and burial and to highlight what creates a landscape and how it evolves through time. In this sense, submarine canyons and turbidite systems represent the most distal depocenter and can hence be considered the most important natural laboratory to study source-to-sink processes. However, few studies look for possible links existing between processes occurring on hinterland source area and in these deep-sea depositional sinks.
The aim of this session is to bring together researchers focusing on how time and processes of sediment erosion, transport and deposition can be constrained from land to the deep sea. We invite presentations that contribute to the advancement of our understanding of sediment dynamics occurring on land or in submarine canyons, with a particular interest in the time scales of sediment transfer and storage through the sedimentary systems and the processes regulating this time scale. Different approaches are welcomed, including but not limited to, in-situ measurements, remote sensing, sediment provenance (e.g., clays, petrography, elemental and isotopic geochemistry) and erosion, detrital geochronology, in modern or ancient sediments, with no limitation of timescale. Studies on smaller scale systems, such as lakes, are also welcomed as they can help to better constrain larger-scale processes. Early career scientists are particularly encouraged to propose abstracts.
