SEABED TOPOGRAPHY MAPPING IN SANGIHE TALAUD WATERS USING MULTIBEAM ECHOSOUNDER [PDF]

Oseanika, 2020
The application of multibeam echosounder for seabed topography has been developing rapidly. Multibeam echosounder is a very efficient way to get a wide seabed topography coverage for each ping, so it can produce high-resolution seabed topography maps. These maps can be used as a reference for further investigation or exploration, for example geological

Integrating multibeam echosounder water-column data into benthic habitat mapping

Limnology and Oceanography, 2021
<p>Kelp forests worldwide are under ever increasing pressure from anthropogenic impacts including kelp harvesting, pollution, and higher sea surface temperatures due to climate change. Marine spatial planning requires accurate mapping of these habitat types to inform effective policy.

The Importance of Under-Keel Sound Velocity Sensor in Measuring Water Depth with Multibeam Echosounder

Energies, 2021
The basic and most commonly used application of modern multibeam echosounders (MBES) is the bathymetric survey. Surface sound velocity errors introduce errors on beam steering angles and consequently errors in depth and position values. Due to systematic

Angular Range Analysis (ARA) and K-Means Clustering of Multibeam Echosounder Data for Determining Sediment Type

Ilmu Kelautan, 2016
Backscatter value was a key to determine seabed characteristic. Level of intensity or backscatter informed through seabed type. One approach was use to analyze seabed type based on the value of backscatter was Angular Range Analysis (ARA).

Definition and application of a quality estimator for multibeam echosounders [PDF]

2012 Oceans - Yeosu, 2012
For modern multibeam echosounders, the use of a robust and reliable quality estimator associated with each sounding is an absolute necessity. Indeed, due to the large volume of data acquired, a lot of time is lost, both during the survey and the post-processing. This is a costly problem for hydrographers.

Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

Limnology and Oceanography: Methods, EarlyView.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...
