Relationship between submarine landslides, channel erosion and thrust fault activity in the Nankai Trough, Japan
Following IODP Expedition 333, frontal ramps of submarine landslides were investigated together with a submarine channel-gully system. In this presentation they are shown to reflect thrust-fault activity in the Nankai accretionary wedge, prior to one of the major stages of movement of the large megasplay fault (MSF). Variations in channel bed slope, height and width of channels and gullies indi...
متن کاملDistribution of acyclic and cyclic biphytanediols in recent marine sediments from IODP Site C0001, Nankai Trough
The distribution of acyclic and cyclic biphytanediols, which are the putative breakdown products of glycerol dialkyl glycerol tetraethers (GDGTs), was investigated for recent marine sediments from Nankai Trough, offshore Kii Peninsula. The most abundant diol is tricyclic biphytanediol of which relative abundance is in the range from 32 to 46%. The carbon skeleton of the detected tricyclic biphy...
متن کاملDistribution of dehalogenation activity in subseafloor sediments of the Nankai Trough subduction zone.
Halogenated organic matter buried in marine subsurface sediment may serve as a source of electron acceptors for anaerobic respiration of subseafloor microbes. Detection of a diverse array of reductive dehalogenase-homologous (rdhA) genes suggests that subseafloor organohalide-respiring microbial communities may play significant ecological roles in the biogeochemical carbon and halogen cycle in ...

متن کاملIODP Expedition 333: Return to Nankai Trough Subduction Inputs Sites and Coring of Mass Transport Deposits
Integrated Ocean Drilling Program (IODP) Expedition 333 returned to two sites drilled during IODP Expedition 322 on the ocean side of the Nankai Trough to pursue the characterization of the inputs to the Nankai subduction and seismogenic zone, as part of the Nankai Trough Seismogenic Experiment (NanTroSEIZE) multi-expedition project. Site C0011 is located at the seaward edge of the trench and S...
