Sedimentology of seabeds, littorals, and coastlines

Sedimentology of seabeds,

littorals, and coastlines

The sedimentology of the seafloor is studied during oceanographic expeditions and coring activities to understand their formation, analyze sediments, reconstruct paleoclimates, identify natural resources, and assess threats to coastal areas.

Oceanographic and coring expeditions play a crucial role in characterizing coastal seabeds and analyzing the processes responsible for their formation. By collecting sediment samples and conducting geophysical measurements, these studies enable the reconstruction of sedimentary architecture and understanding the geological and environmental dynamics that have shaped these regions. These studies also complement work in paleontology and paleoclimatology.

Furthermore, data from these oceanographic and coring studies are of great importance in the field of mining exploration and feasibility studies. Seabeds harbor potential natural resources. These research efforts thus contribute to a better understanding of the marine environment and to more sustainable management of oceanic resources.
