Satlantic Expertise for University

Satlantic Incorporated is to provide expertise in marine monitoring for Memorial UniversityÕs Bonne Bay Ocean Observatory Programme. This system utilises innovative video and acoustic technologies and a suite of sophisticated in situ sensors to continuously sample physical, chemical, and biological properties of the water. Information from the system will be used to study the effects of climate change on the marine ecosystem. The system is currently installed and operating in the Towing Tank at the NRC Institute for Ocean Technology in St. JohnÕs prior to deployment off the west coast of Newfoundland. (read more)

For nearly two years the sales team at VT TSS had been receiving orders for a combined installation of its Meridian gyro-compass and its Dynamic Motion Sensor (DMS). It was, therefore, suggested to VT TSS that it would be easier if the two units could be combined in one box. They would be easier to install and easier to use, and so the company developed the Meridian Heading and Attitude System (MAHRS). One notable new attribute is the deck plane correction, which was made possible by the use of an internal algorithm that can correct the gyroscope with highly accurate... (read more)

Finnish Navy Orders Fansweep 20

ATLAS Hydrographic in Bremen has received an order from the Finnish Naval Research Institute in Helsinki for a 200 kHz Fansweep 20 shallow water multibeam system for installation aboard a new catamaran research vessel to be used for mapping operations in association with the Geological Survey of Finland. Due for commissioning this October, the portable system combining bathymetric measuring and sidescan imaging functions is being supplied together with Linux-based Atlas Hydromap online data acquisition and storage facilities supported by a CARIS HIPS and SIPS software module for post-processing of datasets. The complete assembly is also being interfaced to an autopilot... (read more)

Multibeam Users Look to Future

NATO’s quest for the ultimate shallow water sonar was the subject of one of a series of forward-looking papers presented at a recent international multibeam user workshop held at the Alfred Wegener Institute for Polar & Marine Research, Bremerhaven in association with Atlas Hydrographic. Speaking at the two-day event attended by more than sixty leading sonar specialists, Dr Robert Tyce, Head of the Oceanographic Department of NATO SACLANT’s Undersea Research Centre at La Spezia, anticipated mounting of sonar on unmanned vehicles (AUVs) for high quality hydrographic surveys, seafloor classification and mine detection operations. Other topics reviewed by speakers from Denmark,... (read more)

ADV with Optical Sensor Capabilities

YSI Environmental has developed a multiparameter instrument Ðthe YSI ADV6600- that accurately and reliably measures both water quantity (velocity and direction) and water quality. It has accomplished this by integrating YSI water quality sensor technologies with the advanced Acousic Doppler Velocimeter (ADV) technology of SonTek. The ADV6600 has the capability to measure DO, conductivity, temperature, pH, ORP, pressure, velocity, direction, turbidity, chlorophyll, or rhodamine, chloride, ammonia or nitrate, along with other calculated parameters such as specific conductance and salinity.

Versatile Tide Gauge

Valeport Ltd, UK, has introduced a seabed-mounted tide recorder that makes precise water level measurements where conventional units attached to piers and jetties are not practicable. Applications are in oceanography, hydrography and marine civil engineering projects. Called the MIDAS Tide Recorder, the new instrument is also designed to be part of an in-line mooring. The high accuracy (±0.01 per cent) pressure sensor and temperature sensor is housed in acetal rated to 1,000m water depth. The MIDAS Tide Recorder has a wide range of sampling regimes and rates. It can sample at 1, 2, 4 or 8Hz and can log/output data... (read more)

Calibrating Sonars and Sounders

From Valeport Ltd, comes the SoundBar 2 Digital Bar Checker. Bar Checkers are used to prove data on sound velocity through the water column to enable calibration of swath sonars, echo sounders and other acoustic systems. The SoundBar 2 uses Valeport’s digital ‘time of flight’ sound velocity measurement technique. It has direct compatibility with standard hydrographic procedures and can be set to operate in standard free-running or profile modes; all data is logged and available for output in a variety of industry standard formats. The titanium-housed, 6,000m depth-rated SoundBar 2 operates at 2.5Mhz. Its sound velocity sensor has a range... (read more)

Hydro Suite 120 for GeoDynamics

GeoDynamics has acquired a TEI HydroSuite 120 multibeam system from Triton Elics International (TEI). The HydroSuite includes all the tools needed for a complete hydrographic survey. The system will use the Isis data acquisition software with BathyRT, providing the operator with real-time DTMs to maintain high quality control over the data. Multibeam and sidescan data analysis will be performed in the TEI GIS software DelphMap. The HydroSuite system includes Simrad EM3000 series sonar, a TSS Mahrs sensor and an Odom sound velocity probe. It has been completely field tested and will be integrated on board the client’s vessel in Morehead... (read more)
