This paper briefly reviews the international development of deep-sea sedimentology, covering a broad spectrum of aspects ranging from turbidite to contourite, from deep storm to sediment drift, from sediment trap to on-site observation of the BBL, from time series of sedimentation to cabled sea-floor observation, as well as the “source to sink” studies connecting the modern process to sequence stratigraphy, and the role of deep-sea sedimentation in carbon cycling.All the progress has made deep-sea sedimentology a crucial link in the Earth system science. The paper concludes with three suggestions concerning the future directions of deep-sea sedimentology in the country.
