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...

Optech Sensor Receives Award for Technology Innovation

Optech has been awarded the MAPPS 2011 Geospatial Excellence Award for Technology Innovation. The award was given to the ALTM Aquarius, a compact solution for mapping coastal and inland waterways. Compatible with the ALTM Gemini system, Aquarius collects simultaneous land and water-depth measurements, enabling wholly complete data sets that span the land/water interface.     Designed as a complementary sensor to Optech's Lidar bathymetry systems, Aquarius provides depth information in relatively shallow water environments not previously accessible to conventional topographic mapping sensors alone.     (read more)

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)

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)

Tritech Sensor Selected for Student AUV

Tritech’s Micron sonar has been selected for the latest academic autonomous underwater vehicle (AUV). The acoustic design team at McGill Robotics, McGill University, Montreal, Canada, chose to incorporate a mechanical scanning sonar into their new-build AUV. The team now plan to integrate the Micron sonar into their software system in order to assist close-range positioning and detect objects in low-visibility environments. The team have also updated their AUV with new thrusters and are carrying out modifications to the frame and the pressure vessels. The Tritech Micron sonar is part of Tritech’s SeaKing range of mechanical imaging sonars. The Tritech Micron... (read more)

Ocean Observation Based on Networked Sensor Systems

The Ocean Observatories Initiative (OOI, USA) will construct a networked infrastructure of science-driven sensor systems to measure the physical, chemical, geological and biological variables in the ocean and seafloor. Greater knowledge of these variables is vital for improved detection and forecasting of environmental changes and their effects on biodiversity, coastal ecosystems and climate. Building on last century’s era of ship-based expeditions, recent technological leaps have brought a transformation in the approach to ocean research – the focus on expeditionary science is shifting to a permanent presence in the ocean. The ocean itself presents major obstacles to oceanographic exploration. We cannot... (read more)

CTD Sensor with Integrated UV Antifouling LED

A UV-LED (ultraviolet, 250-300nm @500µW, light-emitting diode) is integrated into the conductivity sensor quartz cell (patent pending) of Idronaut’s 305Plus CTD probe. The UV-LED sterilises the early growth of biofouling, thus eliminating environmental drift in a conductivity sensor. The Idronaut 305Plus CTD Probe complies with the European rules which do not permit the use of Tributyltin (TBT), a very toxic and poisoning (carcinogenic) substance which has been banned by the international government agencies. It is mandatory to protect any recessed conductivity cell, which presents a very small diameter and may get contaminated or even clogged. It also operates in polluted... (read more)
