Pedro Channel is the deepest, central-most seaway on the northern Nicaragua Rise. A revised bathymetric map illustrates a seafloor dissected by numerous canyons and gullies as well as portions of a drowned carbonate bank with keep-up bank morphology. The 3.5 kHz echogram data interpretation in Pedro Channel indicates the banks provide both a line and point source of sediment to the channel floor. Concentric facies belts along the bank margins illustrate the line source concept. Localized zones of coarser-grained deposits at the bases of canyons along the bank margins depict the point source concept. The synthetic seismograms for ODP Site 1000 have low correlation coefficients (0.321). Visual correlation of the synthetic seismogram with SCS data indicates a good correlation of seismic facies with various lithologic intervals. An interpretation of SCCS and MCS data reveals that periplatform sedimentation has dominated Pedro Channel from the early Miocene to recent. Dredge haul analysis suggests that a neritic carbonate bank drowned partially in the middle Oligocene and finally in the early Miocene. Erosion affects the edges of this drowned bank in the middle Miocene. Faults in Pedro Channel illustrate characteristics typical of sinistral strike-slip faults including vertical to sub-vertical faults, faults that splay upward, forced folds, and linear fault traces in map view. ODP Site 998 was selected over a small portion of the Cayman Rise on a small topographic high. Synthetic seismograms for ODP Site 998 have low correlation coefficients (0.168). Despite the low correlation coefficients, turbidite-rich core intervals correlate with SCS intervals having low continuity seismic reflectors. The predominantly pelagic sedimentation at this Site results in a generally continuous seismic reflection character. ODP Site 1001 is located just north of the Hess Escarpment. Synthetic seismograms have low correlation coefficients (0.335), but do permit correlation of SCS A\sp′′ and B\sp′′ horizons with an Eocene-Miocene unconformity and basaltic basement respectively. Hydrosweep data indicates that the Hess Escarpment is dissected by numerous canyons incising along faults. The northwest trending normal faults are suggestive of dextral strike-slip motion.
