Hydrodrothermal chimneys discovered in Alarcon rise by high resolution bathymetry
from MBARI’s AUV (2012)
3-D visualization of the AUV's individual sonar soundings of the same area. This visualization is particularly effective for imaging the hydrothermal chimneys (Dave Caress, MBARI)

Final Comments• Sea floor exploration is a 3D endeavor • Previous multibeam bathymetry is critical for
mission planning• ROV and AUV’s Log is the main source of
spatial (3D) and instrument data• Most of data collected is not GIS ready, it has to
be massaged • Collaborations and technology has enabled us
to explore and map the sea floor, the unexplored final frontier on Earth.
