Seafloor mapping with a cylindrical array
The Journal of the Acoustical Society of America, 2017Seafloor mapping is conducted with different types of arrays. Single beam mapping systems are often constructed with piston arrays. Linear arrays are used for both side scan sonar and for multibeam echo sounders. These conventional approaches to seafloor mapping are typically constrained to a single observation of any one point on the seafloor for any ...

Seafloor map generation for autonomous underwater vehicle navigation
Autonomous Robots, 1996Elevation map generation is an essential component of any autonomous underwater vehicle designed to navigate close to the seafloor because elevation maps are used for obstacle avoidance, path planning and self localization. We present an algorithm for the reconstruction of elevation maps of the seafloor from side-scan sonar backscatter images and ...

Introduction to the seafloor mapping section
Journal of Geophysical Research: Solid Earth, 1986The widespread use of echo sounders on oceanographic research vessels in the years following World War II revolutionized marine geology by providing a technique for routinely measuring the depth of the seafloor along a ship's track. Within two decades, Precision Depth Recorders (PDRs) had been used to identify the major morphotectonic features in the ...

7th International Congress of the Brazilian Geophysical Society, 2001
The use of 3D-seismic surface mapping has proved to be an adequate and reasonably accurate method for proper imaging the deep-water seafloor and the near surface sedimentary column. Attributes such as time, amplitude and dip attitude derived from 3D-seismic surveys are the basis for a thorough assessment of geohazard evaluation.

Frontiers in Seafloor Mapping and Visualization
Marine Geophysical Researches, 2006Over the past few years there have been remarkable and concomitant advances in sonar technology, positioning capabilities, and computer processing power that have revolutionized the mapping, imaging and exploration of the seafloor. Future developments must involve all aspects of the “seafloor mapping system,” including, sonars, ancillary sensors ...

Acoustic navigation for ultra-precise seafloor mapping
The Journal of the Acoustical Society of America, 2005Numerous autonomous underwater vehicles (AUVs) are operating with very precise swath bathymetric mapping systems in ocean depths to 3<th>000 m and greater. Although these systems acquire data from positions known to a few centimeters accuracy with respect to the vehicle position, the positioning of the AUVs is generally no better than ...

Seafloor Habitat Mapping Nearshore San Diego County
California and the World Ocean '02, 2005The California State Coastal Conservancy (SCC), working in cooperation with the San Diego Association of Governments (SANDAG), contracted Thales GeoSolutions, (Pacific) Inc. (TGPI) to perform vessel and airborne data acquisition, processing and interpretation for evaluation of seafloor habitats and environmental resources in the San Diego near shore ...

Seafloor Characterization and Mapping Pods (SCAMP): submarine-mounted geophysical mapping
Oceans '99. MTS/IEEE. Riding the Crest into the 21st Century. Conference and Exhibition. Conference Proceedings (IEEE Cat. No.99CH37008), 2003Summary form only given. In 1998 the Seafloor Characterization and Mapping Pods (SCAMP) were deployed on the US Navy nuclear attack submarine USS HAWKIBILL for unclassified swath mapping and subbottom profiling under the Arctic ice canopy. Data was collected under the SCICEX program.
