Precise Multibeam Acoustic Bathymetry

Marine Geodesy, 1999
The maximum error in ocean depth measurement as specified by the International Hydrographic Organization is 1% for depth greater than 30m. Current acoustic multibeam bathymetric systems used for depth measurement are subject to errors from various sources which may significantly exceed this limit. The lack of sound speed profiles may be one significant

Multibeam bathymetry of glaciated terrain off southwest Newfoundland

Marine Geology, 1997
Abstract Inner St. George's Bay, Newfoundland, was mapped in 1988 using a suite of conventional geophysical and sampling tools. The Quaternary deposits, sea-level history, and Holocene littoral sediments were described in a series of papers. In 1995, part of the previously mapped area was imaged using a multibeam mapping system.

3D seismic-derived bathymetry: a quantitative comparison with multibeam data

Geo-Marine Letters, 2019
This study compares bathymetry extracted from 3D seismic data at two Australian study sites of differing morphological complexities to two sources of collocated multibeam data: 50-m and 5-m multibeam digital bathymetric models (DBMs). Seafloor horizons are extracted from the 3D seismic data and converted to depth using sound velocity profiles collected

Seamless splicing of digital multibeam bathymetry maps

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
For the problem of splicing two depth maps measured by multibeam bathymetry system. the seafloor is measured according to multibeam principle, and the data obtained are corrected by five factors. Further, Edge beams of two maps are trimmed to align. On this basis, depths of two maps are added using inverse distance weight(IDW) in their overlap region ...

Automated error detection in multibeam bathymetry data

Proceedings of OCEANS '93, 2002
For a variety of reasons, multibeam swath sounding systems produce errors that can seriously corrupt navigational charts. To address this problem, the authors have developed two algorithms for identifying subtle outlier errors in a variety of multibeam systems. The first algorithm treats the swath as a sequence of images.

Multibeam Bathymetry of the Håkon Mosby Mud Volcano

Marine Geophysical Researches, 2005
The Hakon Mosby Mud Volcano is a natural laboratory to study geological, geochemical, and ecological processes related to deep-water mud volcanism. High resolution bathymetry of the Hakon Mosby Mud Volcano was recorded during RV Polarstern expedition ARK XIX/3 utilizing the multibeam system Hydrosweep DS-2.
