The Ocean Drilling Program (ODP) Leg 131, which drilled in the Nankai Trough in the western Pacific Ocean, has shown for the first time that turbidity currents are deflected and reflected against the trench slopes, so that in the trench outer slope there is a predominant pattern of currents, carrying terrigenous sediments, apparently coming from the open-ocean Shikoku Basin directly toward the trench landward slope. Herein we summarize the evidence for flow rebound at Site 808 of ODP Leg 131, and we show that these results have important implications for the interpretation of paleocurrents in ancient linear turbidite systems.
