NexSon Bathmetrymetric and Oceanographic Sensor Packages

OceanTools Ltd announce the launch of their NexSon Bathymetric & Oceanographic Sensor packages. The NexSon Bathy/OSP contains high accuracy conductivity, temperature, pressure and altitude measurement probes for precision depth, altitude, conductivity, density and velocity of sound measurements. Systems are available in depth ranges of 700m, 1200m, 2000m and 4000m. Data from the subsea Bathy/OSP units is displayed on a stand-alone surface control unit, a NexSon sonar control unit, or on a PC running the Bathy/OSP software. The surface unit also contains an optional integral digital barometric pressure measurement. A range of output data strings are available to ensure compatibility with... (read more)

Sensor Fusion Applications at EGU 2014

Optech, Canada, will be at the European Geosciences Union General Assembly 2014 from 27 April to 2 May in Vienna, Austria. Attendees with an interest in Lidar/sonar fusion or disaster response will enjoy Optech Worldwide Channel Partner manager Dario Conforti’s presentation explaining how Optech distributor Codevintec surveyed the wreck of the Costa Concordia. By combining a motion-compensated Optech ILRIS and a Teledyne RESON SeaBat multi-beam echo sounder on a research vessel, Codevintec mapped the wreck both above and below the surface of the water in a single pass, employing specialised software to merge and visualise their data in real time...

PAVS-150 Phased Array Velocity Sensor

Teledyne RD Instruments (RDI) has released the 150 kHz Phased Array Velocity Sensor (PAVS) for extended-range navigation applications. The PAVS150 is the industry's first 1,000-metre depth-rated compact Doppler Velocity Log (DVL) designed to provide precision velocity data at up to 500 metres of altitude above the seafloor. Driven by customer demand, this extended-range bottom-tracking capability makes the PAVS150 suited for aiding navigation systems on board any platform where the ability to transition from the deep waters of the open oceans to the shallow operating environments of the littoral zone is seen as a critical enabler.Designed with the Unmanned Underwater Vehicle...

UV Nitrate Sensor Added to Buoy System

The National Oceanic and Atmospheric Administration's (NOAA, USA) Chesapeake Bay Interpretive Buoy System (CBIBS) is a network of observing platforms that deliver meteorological, oceanographic and water-quality data live to the web at hourly intervals. The network has recently come under budgetary pressure and has been threatened with closure. In a cooperative effort to highlight the utility and value of the system, Satlantic (Canada) has recently partnered with CBIBS Project Manager Doug Wilson to provide a SUNA UV nitrate sensor for the Susquehanna site. It is hoped that the addition of the real-time continuous nutrient time series data will help promote the... (read more)

nke NOSS In Situ Density Sensor Presentation

nke Optical Salinity Sensor (NOSS) has emerged as one of the first underwater sensors for in situ refractive index measurement in the past years, opening up the scope of possibilities of direct access to density parameter. A presentation will take place in Southampton during Ocean Business Exhibition on Wednesday 15 April from 9-10AM in Node Room 064/03 of the NOC, presented by Damien Malardé, research engineer in nke Instrumentation. The introduction in 2010 of the Thermodynamic Equation of Seawater TEOS-10 has represented an important milestone towards the implementation of a global thermodynamic ocean model. An accurate evaluation of the ocean’s... (read more)

Canadian-UK Collaboration for Tidal Sensor Technologies

Canadian and British researchers will join forces to collaborate on two projects in developing new sensing technologies for tidal energy applications. The two project teams each feature industry and academic expertise from Canada and the UK and will introduce environmental monitoring and measurement sensor systems aiming to reduce risk and uncertainties associated with the deployment and operation of in-stream tidal devices. Sensor deployment and testing will be carried out in both Canadian and UK waters. Additional expected outcomes are to build Nova Scotia technical capacity in tidal energy and to contribute to the sector’s emerging global supply chain. The two... (read more)

Imagenex Adds Sonar and Sensor Interface Relay

Imagenex has released the Model 878 high-resolution sidescan sonar which runs two sonars simultaneously on each side at different sound wavelengths for enhanced image clarity. The new DT100 Sensor Interface Relay (SIR) provides a central connection point for bathymetric sensors including sonar (1 or 2 units), GPS, MRU, gyro/heading, and sound velocity. The DT100 multibeam echo sounder has been revised. The sidescan sonar Model 878 'RGB' (triple simultaneous frequencies) has undergone a facelift and become more affordable. Both models are equipped with an optional echo sounder and a built-in orientation module as well as depth and temperature sensors. Powered by... (read more)

Longest Multi-Sensor AUV Pipeline Inspection

KONGSBERG has completed the world's longest multi-sensor AUV pipeline survey using one of its HUGIN 1000 Autonomous Underwater Vehicles (AUV). The pipeline inspection took place from 9th to 11th February 2011, in the Hjelte fjord near Bergen, Norway and the HUGIN 1000 was operated from the Royal Norwegian Navy vessel HNoMS Maloy. The subject of the inspection was two subsea pipelines going to the Mongstad oil refinery. The HUGIN 1000 AUV was equipped with a suite of KONGSBERG imaging equipment including the HISAS 1030 synthetic aperture sonar, EM3002 multi-beam echo sounder and an optical camera with LED lighting. The instruments... (read more)

First Seaglider with Rockland Scientific Turbulence Sensor

Kongsberg Underwater Technologies, USA, has delivered the first Seaglider vehicle equipped with a Rockland Scientific International (RSI) MicroPod turbulence sensor. The vehicle was commissioned by the UK's University of East Anglia (UEA). The MicroPod package is the result of extensive collaboration between KUTI and RSI in an effort to develop a sensor solution that is suitable for integration on Seaglider’s low-drag composite fairing. This sensor configuration minimises any potential impact on the high glide efficiency of the Seaglider. Ocean turbulence is being recognised as an increasingly important parameter for understanding and modelling climate change. It provides a measure of the... (read more)

Xchange Sensor Heads Now Calibrated in Europe

AML Oceanographic (AML, Canada) has partnered with OSIL to offer Xchange sensor recalibration services at OSIL’s facilities in the UK. With a European recalibration centre, field-swappable sensor-heads become even more convenient for European users of oceanographic instrumentation. OSIL is expected to begin accepting Xchange sensor heads for recalibration by 1 March 2014. AML’s Xchange line is the industry’s only series of field-swappable sensor heads. Each sensor head contains its own embedded calibration, allowing the sensor to work with any AML instrument. Field-swappable sensors also streamline recalibration; instead of sending the entire instrument back to a calibration centre, a recalibrated sensor-head... (read more)
