The world's continental shelves are the sites of vast resources of food, energy and minerals, the exploitation of which is continuously increasing. Fluctuating global sea levels throughout the Quaternary period produced multiple transgressive and regressive cycles that profoundly affected and shaped these shelves. The complex interactions among climate, sea level, tectonics, oceanography and sediment input have formed distinctive sediment packages on each shelf and provide a guide to the interpretation of older shelf sequences throughout the geological record. This Memoir compiles studies on 23 selected shelves from all the continents, focusing on their evolution and examining the patterns of sedimentation during the past approximately 125 000 years. In addition to providing basic background information for each area, the chapters consider specific aspects of continental shelf research, from seismic stratigraphy to geomorphology, from palaeoceanography to palaeo sea-level reconstruction and from palaeontology to geochemistry.Although shelf areas account for little more than 8% of the marine areas of the world, they are the part of the sea most used for ... of direct economic interest (e.g. ilmenite, magnetite, cassiterite, chromite, rutile, zircon, rutile, gold and diamonds). ... Not only do mineral resources make the shelf the most relevant part of the marine realm but shelf waters are also, by far, the richest part of the ocean (Wei et al.
