The Vema transform region viewed from the northeast. Figure is based on multibeam data obtained during cruises EW9305, and S-19 and S-22 (RV Akademik N. Strakhov). The Vema lithospheric section (VLS) is clearly visible. Location of magnetic chrons C5 and C6, of the Nautile submersible profiles, and of the rocks sampled along the VLS, are indicated. The inset shows a satellite-derived gravity image of the Central Atlantic, where the Vema fracture zone (FZ), the transverse ridge and the long-lived EMARS can be identified.

The Global Multi-Resolution Topography (GMRT) synthesis is a continuously-updated compilation of seafloor topography including multibeam bathymetry data from throughout the global and coastal oceans (view contributors). It is maintained as a multi-resolution gridded digital elevation model of seafloor bathymetry to ~100 m spatial resolution.

Perspective view of the eruptive fissure along the axis of the East Pacific Rise from 9°49N to 9°51N looking to the north. This region is the site of documented volcanic eruptions in 1991-92 and 2006. Image is created from very high resolution bathymetry data gridded at 5 meter grid interval collected with the Autonomous Underwater Vehicle ABE. Data from Fornari et al., AGU Monograph 148, 2004. Image made using GeoMapApp.

This centimeter-scale resolution bathymetric image of the east face of the Faulty Towers and Twin Peaks Complexes was formed using a 675 kHz scanning sonar mounted on the ROV Jason I. It was compiled from 115 precisely navigated vertical and down-looking surveys using Jason under remote control. The corresponding digital still mosaic of Faulty Towers is shown in the image Photomosaic of Faulty Towers at Mothra.
