High resolution seafloor mapping for marine geology and archeology.



Wednesday — November 16, 2011
Pacific Forum — 3:00 p.m.

Detailed photographic and bathymetric maps of the seafloor with resolutions better than five centimeters have broad applicability for studies in marine geology, biology, and archeology. This talk will discuss the use of stereo vision, high frequency (1375 kHz) multibeam sonar, and structured light laser imaging to produce these maps with robotic vehicles. Comparisons between these sensors have been made in numerous contexts during the 2010 and 2011 field seasons of the EV Nautilus ocean exploration program. The goal of this work is to create self-consistent multi-sensor data products that can be directly compared and fused. Results will be shown from efforts to map archeological sites with millimeter level gridding, and a multi-faceted research program at the Kolumbo volcanic crater near Santorini, Greece. Results will also be presented for transferring these methods to a novel Lagrangian imaging platform.
