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 ...

High-Resolution Acoustic Seafloor Mapping
Offshore Technology Conference, 1988ABSTRACT SeaMARC/S is a 150 kHz towed sonar mapping system that produces synoptic acoustic backscatter images and hydrographic-quality swath bathymetry charts in water depths to 1400 meters. The system is versatile, operating in a range of swath widths from 1000 meters for reconnaissance surveys to 50 meters for ...

Mapping the seafloor from space
Endeavour, 1996Abstract Highly sensitive radar altimeters in Earth orbit sense minute changes in sea level caused by the gravitational attraction of topography on the seafloor. Algorithms that predict the shape of the seafloor implied by the altimeter data allow researchers, for the first time, to produce detailed maps of the largely unexplored Southern Oceans ...

History of Modern Seafloor Mapping
2016Over the last century, remotely sensed mapping of continental shelf seafloor topography has had a rich history of applied research with varying techniques, all of which strive to accurately visualize the submarine benthos. Many early techniques (e.g., three-dimensional hachure maps) relied solely on the researcher’s knowledge and cartographic skills in

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.
