Compiled visualization of datasets from the East Pacific Rise (EPR) Integrated Study Site (ISS). At right, ship-based EM300 bathymetry (25-m resolution) shows the axial high between 9°46'N and 9°56'N [White et al., 2006]. A higher resolution bathymetry data set (5-m resolution) collected in 2001 by the autonomous underwater vehicle (AUV) ABE is overlain and shows greater details of the volcanic terrain [Fornari et al., 2004; Escartin et al., 2007].

Bathymetric map of the East Pacific Rise focused study area near 9°50'N showing the locations of high and low-temperature vents prior to and after the 2005-2006 eruptions. Vent locations active before the 2005-2006 eruptions are labeled on right. All except those labeled in blue continued to be active after the 2005-2006 eruptions. New vent sites that became active after the latest eruptions and were sites of experiment deployments and sampling are labeled on left (e.g., Mkr #s).

(right) Perspective image of multibeam bathymetry for the EPR 2nd order segment between Clipperton and Siqueiros transforms. EPR ISS focused study area near 9&deg50’N shown by red dot. Black line shows the location of the axial summit trough [Soule et al., 2009] where most of the hydrothermal vents and biological communities are located.

a) Bathymetry from the 13 N region of the Mid-Atlantic Ridge. Gray shading indicates two core complexes that have formed in the middle of a spreading segment. The box is the region interpreted in (b). Black lines: borders of the MAR ridge axis, the tops of rotated faults, and schematic striations on core complexes. B: basins that have formed during the outward rotation of the tops of the faults. b) Line drawing of the bathymetry in the box in (a) showing striated core complexes and the tops of rotated faults. B: basins as in (a).

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.

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.
