Extended Continental Shelf delineation (i.e. beyond the 200 M exclusive economic zone) under the UN Convention on the Law of the Sea requires Coastal States to define their continental margin using criteria provided in Article 76. These criteria include specific morphological metrics and geomorphological and geological assessments. Since 2001, 70 Coastal States have filed 77 submissions with the Commission on the Limits of the Continental Shelf on the outer limits of their continental shelves beyond 200 M. These submissions contain scientific evidence and arguments based on interpretation of significant new geomorphologic and geologic data compilations along deep water parts of continental margins throughout the World. These new data have led to a wealth of new understanding. This session calls upon researchers and practitioners to present these new continental margin data and data compilations and show how our understanding of deep water margins has evolved through the process.
Public information: Mapping for delineation of coastal State's extended continental shelves have resulted in a plethora of new geomorphologic and geologic data along continental margins throughout the globe. These new, digital, and sometimes extensive data sets have and will result in vast new understanding of continental margin processes.
