In 1995, R/V Maurice Ewing cruise EW9501 collected 5200 km of high-quality multichannel reflection profiles and 104 wide angle sonobuoy profiles in the Venezuelan Basin and over the Beata Ridge. These data provide images of the entire Caribbean crust, from seafloor to Moho, and verify earlier models of a two-"layer" crust. The EW9501 data also image the internal structure of these layers, revealing previously unseen features. The upper crustal "layer" is actually a complex sequence, whose stratigraphy is analysed to show that the thickest part of the Caribbean volcanic plateau was experiencing east-west compressional deformation during the last stages of its emplacement.
