Ocean chemistry and deep-sea sediments

Summary•Geological, morphological and geotechnical understandings of thearea is the key for understanding the slide occurrences and slidedevelopments.•Slides can have developed from the distal part and failed along thesediment boundaries. Slides stepped up to shallow levels until the resistancein terms of thickness and degree of consolidation became too large for afailure.•Slides can have developed in the gas hydrate dissociation areafrom the proximal part and failed then afterwards with or withoutretrogressive sliding.•Changes in sea level and climatic driven processes from low to highlatitudes are important for a regional or global assessment of downslopeand alongslope transport of sediments.
