Numerical modeling and simulation technique in time-domain for multibeam echo sounder

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2018
A Multibeam Echo Sounder (MBES) is commonly used for rapid seafloor mapping. We herein present a time-domain integrated system simulation technique for MBES development. The Modeling and Simulation (M&S) modules consist of four parts: sensor array signal

Automatic Processing of High-Rate, High-Density Multibeam Echosounder Data [PDF]

open access: yes, 2003
Multibeam echosounders (MBES) are currently the best way to determine the bathymetry of large regions of the seabed with high accuracy. They are becoming the standard instrument for hydrographic surveying and are also used in geological studies, mineral ...

Submarine depositional terraces at Salina Island (Southern Tyrrhenian Sea) and implications on the Late-Quaternary evolution of the insular shelf [PDF]

open access: yes, 2018
The integrated analysis of high-resolution multibeam bathymetry and single-channel seismic profiles around Salina Island allowed us to characterize the stratigraphic architecture of the insular shelf.

A Novel Cone Model Filtering Method for Outlier Rejection of Multibeam Bathymetric Point Cloud: Principles and Applications

open access: yesSensors, 2023
The utilization of multibeam sonar systems has significantly facilitated the acquisition of underwater bathymetric data. However, efficiently processing vast amounts of multibeam point cloud data remains a challenge, particularly in terms of rejecting ...

Discovering the Fine-Scale Morphology of the Gulf of Cádiz: An Underwater Imaging Analysis

open access: yesJournal of Marine Science and Engineering, 2022
The dense and deep water flow that leaves the Mediterranean Sea to the Atlantic flows through the upper and middle slope of the Gulf of Cádiz as a powerful bottom stream that models and interacts with bathymetry.

Flow and retreat of the Late Quaternary Pine Island-Thwaites palaeo-ice stream, West Antarctica [PDF]

open access: yes, 2010
Multibeam swath bathymetry and sub-bottom profiler data are used to establish constraints on the flow and retreat history of a major palaeo-ice stream that carried the combined discharge from the parts of the West Antarctic Ice Sheet now occupied by the ...

Sparse Gaussian Process SLAM, Storage and Filtering for AUV Multibeam Bathymetry

open access: yes2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018
With dead-reckoning from velocity sensors, AUVs may construct short-term, local bathymetry maps of the sea floor using multibeam sensors. However, the position estimate from dead-reckoning will include some drift that grows with time. In this work, we focus on long-term onboard storage of these local bathymetry maps, and the alignment of maps with ...

Bathymetry and Geomorphology of Shelikof Strait and the Western Gulf of Alaska

open access: yesGeosciences, 2019
We defined the bathymetry of Shelikof Strait and the western Gulf of Alaska (WGOA) from the edges of the land masses down to about 7000 m deep in the Aleutian Trench.
