Deepwater Multibeam for COMRA

China’s Ocean Mineral Research and Development Agency (COMRA) has recently taken delivery of its R/V Da Yang for a new generation of deepwater multibeam technology SEA BEAM 3012. The upgrade to 3012 was installed in autumn 2002 and accepted in February 2003 following intensive deepwater trials. SEA BEAM 3012 offers a fully motion-compensated PC-based deepwater multibeam system, achieving motion compensation by swept beam technology. (read more)

Opportunistic Multibeam Surveying

Deep-sea Research Expeditions Expand Multibeam Bathymetric Map of Seafloor

Currently only ten to fifteen percent of the ocean floor has been mapped at resolutions of 100-metre pixel size or better and the vast majority of this mapped area is within territorial waters. One way to significantly increase seafloor coverage is to outsource data collection to non-hydrographic vessels or ships of opportunity. However, data currently being collected by these vessels are largely unmanaged, leading to possible redundant coverage and/or inconsistent quality. It is a good idea that the scientific and hydrographic communities make effective use of ships of opportunity in order to optimise data collection in the immense areas in... (read more)

NetSurvey Multibeam Advances

NetSurvey have recently completed two contrasting projects which they claim advance multibeam technology. The first project was for Pacific Engineering Company (PECO) in Russia and involved supplying personnel, software and multibeam hardware for an Ice Scour survey prior to pipelay operations. The survey, using Reson’s 8125 highest resolution multi-beam echosounder, identified sand wave fields whose height was only 3cms and easily determined the 20-30 cm deep ice scours. A total of nearly 1.8 Billion soundings were collected over the 31 days of survey, which works out at an average of 660 soundings per second. This data was handled by a... (read more)

New Multibeam System

Atlas Fansweep Coastal, the first of a new series of advanced Atlas Fansweep 30 multi-beam echosounders designed to exceed IHO standards over depths in excess of 600m, has been introduced by Atlas Hydrographic. Developed for both hydrographic survey and oceanographic research applications covering waterways and coastal regions extending to continental shelf boundaries, the system features enhanced levels of data quality to reduce general post-processing requirements. Operating between 100 and 200kHz, with broadband frequency coverage depending on water depth and conditions, it additionally features simultaneous multi-ping technology for concurrent transmission of multiple steered pings in a water column. This ensures significant... (read more)

Faster Multibeam Data Handling

CARIS has released a 64-bit version of its hydrographic processing software HIPS and SIPS. This new version HIPS and SIPS 7.1 will provide users who have access to a 64-bit computer the ability to handle large multibeam sonar datasets even faster. In-house tests revealed that the CUBE surface creation and Merge processes are now 15-30% faster respectively. The 64-bit technology also allows access to larger banks of RAM, increasing the ability to multi-task while processing. HIPS and SIPS supports over 40 sonar and Lidar formats, allowing it to process data from virtually any system configuration. The software also includes... (read more)

Multibeam Water Column Imaging

Kongsberg Maritime’s new multi-beam echo sounder, EM 3002, extends the functionality of multi-beam echo sounders to cover 3D imaging of biomass and other acoustic reflectors that might be present in the water column. 160 acoustic beams are sampled digitally with a spatial resolution of 15cm for each ping, creating a digital image of a slice of the water mass under the transducer. When the ship is sailing forward, a 3D description can be obtained by combining the images from several pings. The raw display image is available as part of the operator interface. An option to the SIS operating software... (read more)
