Alaska’s Undersea Volcano Mapped

Thales GeoSolutions (Pacific), an ocean engineering, surveying and mapping company, has successfully mapped Alaska’s first known active undersea volcano. The volcano lies in the Northwest portion of Amchitka Pass, Southeast of Semisopochnoi Island in the Aleutians. The National Marine Fisheries Service (NMFS), Auke Bay Laboratory (Juneau, AK) contracted Thales GeoSolutions (Pacific) to map seafloor habitat for deep-sea coral research. The volcano was originally discovered in 2002 by NMFS biologists, Bob Stone and Dr Jon Heifetz, who used the Delta submarine to video coral habitat on the volcano. A combination of RESON 8111 and 8150 multibeam echosounders were used to produce... (read more)

NaviSound 110 Single-beam Echosounder

RESON has introduced the NaviSound 110 Single-beam Echosounder, a compact, low-cost single frequency digital echosounder designed for a range of hydrographic and remote operating applications. The NaviSound 110 is reliable and easy to operate. Compact and lightweight, the system is designed as a unique, paperless ‘black box’. The unit has a dedicated channel module that can be configured to operate with any commercial echosounder transducer and an affordable Side-Looking Sonar (SLS) option is also available. Delivered with a PC Windows terminal and control program, the NaviSound 110 data output is supported by all survey software packages. The control and display... (read more)

Kongsberg EN250 for HOV

After the delivery of two Kongsberg hydrographic systems for HOV vessels, Bennex Holland BV has now received an order for a Kongsberg EN250 single beam echosounder with spare parts and an in-house developed interface for connecting four 50kHz transducers with special interfacing to the onboard computer systems. This special interface contains data information and indicates which transducer is connected to the echosounder system. For many years Bennex Holland BV has been developing special interfacing for several applications inside acoustic systems for the RDN. The new system will be delivered in October 2003. (read more)

First Parametric ROV Echosounder

Adaptation has begun of the Innomar Technologie SES-2000 parametric echosounder for use on ROVs. The advanced sounder functions with a pencil-thin acoustic beam that is a highly effective tool in penetrating mud and sediment to provide high resolution sub-bottom profiles. Aquadyne is project-managing the work of Innomar and DeepOcean in developing the first parametric echosounder capable of deployment on an ROV down to 2,000 metres. The development is being initiated as part of a contract that DeepOcean holds with Statoil and, as project manager, Aquadyne responsibilities also include raising finance for the work. Completion of the project is scheduled for... (read more)

Knudsen Echosounder for US Navy

Knudsen Engineering Ltd is to fulfil a volume order from the US Naval Oceanographic Office at the Stennis Space Center (Mississippi), including eight 320BR deepwater echosounder plus spares kits. These instruments are two-channel (3.5/12kHz), rack-mounted, high-power systems used for full ocean depth survey. Using a Windows interface data display, the systems incorporate chirp-and-correlation processing to achieve low noise and high-resolution sub-bottom profiles. (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)

ATLAS for Columbian Navy

ATLAS Hydrographic, in association with Ferrostaal de Colombia, has been contracted by the Colombian Navy's Hydrographic Service to supply ATLAS HYDROSWEEP MD-2 30kHz 5000m and ATLAS FANSWEEP20 200kHz shallow water multi-beam echosounder systems. The systems will be commissioned and installed on two hydrographic survey vessels operating from Cartagena and used for national survey operations. Each system is being supplied together with TSS motion sensor, Valeport sound velocity profiler and Trimble DGPS facilities. Support software comprises Coastal Oceanographics' HYPACK MAX and HYSWEEP modules for acquisition and storage of all data, in addition to CARIS HIPS and SIPS for post-processing operations.

First Bluetooth Echosounder

The SonarMite Echo Sounder is the result of nearly two years research and development resulting in a series of equipment designed around the WinSTRUMENT concept and using the latest portable computers, integrated with new measurement technologies. The SonarMite extends the idea of a rugged design and minimalist interface to produce a 'Blue Box' system in which the user interface is provided by integrated software running on a portable computer connected via a Bluetooth link. The use of wireless technology enables the instrument to be waterproof and capable of use in a hostile environment, while the more sensitive computer features may... (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)
