UTILIZATION OF MULTIBEAM ECHOSOUNDER DATA FOR BATHYMETRY MAPPING: EVALUATION WITH INTERNATIONAL STANDARD

Jurnal Geofisika Eksplorasi
Bathymetric mapping is crucial for understanding seabed conditions, especially in maritime countries like Indonesia. This study evaluates the quality of bathymetric data acquired using Multibeam Echosounder (MBES) in Jakarta waters. The acquired data was

Inverse distance weighting method optimization in the process of digital terrain model creation based on data collected from a multibeam echosounder

Applied Geomatics, 2020
This paper presents the optimization of the inverse distance weighting method (IDW) in the process of creating a digital terrain model (DTM) of the seabed based on bathymetric data collected using a multibeam echosounder (MBES).

High-Performance Compression of Multibeam Echosounders Water Column Data [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
Over the last few decades, multibeam echosounders (MBES) have become the dominant technique to efficiently and accurately map the seafloor. They now allow to collect water column acoustic images along with the bathymetry, which is providing a wealth of new possibilities in oceans exploration. However, water column imagery generates vast amounts of data

Control of the repeatability of high frequency multibeam echosounder backscatter by using natural reference areas [PDF]

, 2018
The increased use of backscatter measurements in time series for environmental monitoring necessitates the comparability of individual results. With the current lack of pre-calibrated multibeam echosounder systems for absolute backscatter measurement, a ...

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

A Multibeam-Based SLAM Algorithm for Iceberg Mapping Using AUVs

IEEE Access, 2018
Using autonomous underwater vehicles (AUVs) for mapping underwater topography of sea-ice and icebergs, or detecting keels of ice ridges, is foreseen as enabling technology in future arctic marine operations.

Seagrass Habitat Suitability Models using Multibeam Echosounder Data and Multiple Machine Learning Techniques

IOP Conference Series: Earth and Environment, 2022
Seagrass beds are important habitats in the marine environment by providing food and shelter to dugongs and sea turtles. Protection and conservation plans require detail spatial distribution of these habitats such as habitat suitability maps.

Decadal‐Scale Bathymetric Change in a Shallow Coastal Bay

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Coastal marshes and bays must accumulate sediment to maintain their position relative to mean sea level during periods of sea level rise (SLR). Resuspension of bay‐bottom sediment, which together with tidal inundation promotes marsh deposition, is sensitive to water depth, but quantitative measurements of bathymetric change across shallow bays

Coralligenous banks along the western and northern continental shelf of Sardinia Island (Mediterranean Sea)

Journal of Maps, 2022
Mapping of coralligenous banks was carried out along the continental shelf of the northern and western margin of Sardinia Island (Italy, western Mediterranean Sea) in the context of the European Marine Strategy Framework Directive (MSFD, 2008/56/EC ...
