Seafloor Survey Around the Atlantis II Seamounts Using an Autonomous Underwater Vehicle
Abstract
A comprehensive seafloor and sub-bottom survey using an autonomous underwater vehicle (AUV) equipped with a variety of acoustic and,optical sensors is proposed for the Atlantis II Seamounts area. The AUV sensors include a multibeam echo sounder, sidescan sonar, su,b-bottom profiler and still image camera. The primary scientific objectives include estimating the geoacoustic properties of seafloo,r sediments from sonar signal returns and confirming objects on the seafloor from still images. The survey area is on the pathway of, the Gulf Stream, so high speed currents are expected and pose a great challenge to operate the AUV. Hence, another scientific and e,ngineering objective of this proposal is to optimize AUV survey planning by creating a numerical simulator with realistic environmen,tal conditions and incorporating existing marine geological measurements in the area. Ultimately, the AUV data will contribute to se,afloor and sub-bottom databases and improve our understanding of seamount geology.
