Multisensor mapping of the deep seafloor with the Autonomous Benthic Explorer
2000
We used the Autonomous Benthic Explorer (ABE) to create maps of an active spreading center on the mid-ocean ridge at a depth of 2600 meters. We took advantage of ABEs precise navigation and bottom following capabilities and produced detailed bathymetric maps with a scanning sonar, and photo-mosaics using ABE's video snapshot system, and measured the temperature and optical backscatter of the water. Refinement of ABE's transponder fixes, based on using returns gathered at the vehicle, contributed to the consistency of the results.
