Australian multibeam guidelines

, 2018
Australia’s Multibeam Guidelines were established by the AusSeabed consortium. The guidelines provide procedures mainly on survey planning, data acquisition and submission i.e. from the pre-survey planning phase to the data submission phase, off the ship. They are designed for a range of audiences, from those experienced in seafloor mapping using swath

Calibration of multibeam echo sounders: a comparison between two methodologies [PDF]

, 2012
Multibeam echo sounders (MBES) are widely used in applications like seafloor imaging, fisheries, and habitat mapping. Calibration of acoustic backscatter is an important aspect of understanding and validating the performance of a MBES.

Seabed sediments (grain size) of Nordland VI, offshore north Norway

Journal of Maps, 2017
This paper presents a seabed sediments (grain size) map of the Nordland VI area (25,000 km2) off the Lofoten islands, north Norway. The map is based on multibeam echosounder data (bathymetry and backscatter), visual analysis of 215 video transects (each ...

Precoding in multigateway multibeam satellite systems [PDF]

, 2016
This paper considers a multigateway multibeam satellite system with multiple feeds per beam. In these systems, each gateway serves a set of beams (cluster) so that the overall data traffic is generated at different geographical areas.

The first ultra-high resolution Digital Terrain Model of the shallow-water sector around Lipari Island (Aeolian Islands, Italy) [PDF]

, 2015
Very high resolution bathymetric map obtained through multibeam echosounders data are crucial to generate accurate Digital Terrain Models from which the morphological setting of active volcanic areas can be analyzed in detail. Here we show and discuss
