Multibeam bathymetry data of the western part of the Romanche Trench (Equatorial Atlantic)

Data in Brief, 2021
We present the multibeam bathymetry data of the western part of the Romanche Trench (Equatorial Atlantic) which is the main natural corridor that regulates inflow of Antarctic Bottom Water into the eastern basin of the Atlantic Ocean.

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.

The Invention and Developing of Multibeam Echosounder Technology [PDF]

Polish Hyperbaric Research, 2018
Abstract When a man has mastered the ability to travel by sea, he began to wonder what is the depth clearance under the keel and how to measure the depth. Initially, only coastal shipping was practiced. Cargo ship sailing, fishery, underwater scientific research, recreational diving as well as resource exploration and operation of ...

Towards a fully calibrated multibeam echosounder [PDF]

Proceedings of Meetings on Acoustics, 2012
Multibeam Echo Sounders (MBES) are designed primarily for high resolution bathymetry. Therefore, absolute sound pressure levels measurements have not been a high priority so far. There is, however, a growing demand for the characterization of, for example, species, sediments, man made objects, and oil pollution.
