Composite bathymetry map of P-vent area EPR (2004)

Composite bathymetry map of P-vent area EPR (2004)

A composite map (0.5m grid, 0.25m contours) created from multiple DSV Alvin dives. Detailed morphology around vent structures and fissure within the axial trough floor are evident. Lava pillars (1-2m diameter) are evident at eastern wall of the axial trough. Inset shows 3-D view of P vent (looking north).
