100th Ice Profiler

ASL Environmental Sciences has shipped two Ice Profilers to ConocoPhillips in early August 2008, bringing the total number of Ice Profilers sold to 100. Since the late 1990's when ASL, in collaboration with the Institute of Ocean Sciences, first introduced this advanced upward looking sonar (ULS), the demand for high resolution measurements of sea ice thickness and the detailed under-ice topography of sea ice has increased enormously. Ice research programs have expanded considerably, driven by the major changes in the ice regime of the Arctic Ocean and other areas. Offshore oil and gas companies are increasingly embarking on...

Acoustic Zooplankton Fish Profiler

The Acoustic Zooplankton Fish Profiler (AZFP) offers a new, economical way of monitoring the presence and abundance of zooplankton and fish within the water column by measuring acoustic backscatter returns at multiple ultrasonic frequencies. The AZFP has an unmatched combination of multiple frequency operation with low power and long endurance that fits your budget. The AZFP can collect data continuously up to one year at high temporal and spatial resolution. (read more)

Current Profiler Shallow Water

OSIL has recently supplied several SonTek Argonaut-XR (Extended Range) Acoustic Doppler Current Profilers for use in projects where shallow-water current monitoring is required. The Argonaut XR is specifically designed for mounting on the bottom of a river, channel, port or near-shore in less than 40m depth of water. It has a multi-cell current profiling feature that includes special mode which automatically adjusts one of the measurement cells for changing water-level. This means that the Argonaut-XR can adjust measurement volume height to report depth-averaged velocity over the entire water column, or over a user-programmable range (even with tide variation). The Argonaut... (read more)

FlowQuest Current Profiler Sales

The sale of LinkQuest's FlowQuest line of acoustic current profilers has grown rapidly since its introduction. An extensive line of models has been used for a large number of diverse applications worldwide. LinkQuest recently provided Columbia University with a FlowQuest 600 system with WaveQuest directional wave measurement option, bottom tracking option, and Data Fusion function interfacing to a third party sensor and a FlowQuest 300 system with bottom tracking option and Data Fusion function. These systems, along with previously purchased FlowQuest 600 systems, will initially be used in current and wave studies in Indonesian Seas. All profilers are equipped... (read more)

ADCP in Moored Profiler

McLane Research Laboratories (USA) has integrated and tested a Nortek acoustic Doppler current meter for the Mclane Moored Profiler (MMP), a wire-crawling profiler. In collaboration with NortekUSA, successful tests of the Nortek Aquadopp Profiler mounted to the MMP were expanded in fully integrating the current meter into the MMP data control and acquisition system for seamless deployment configuration and data collection. The MMP autonomously profiles the water column in a time-series along a fixed tether. Profiling depth, time intervals and pressure stops are user-defined, and profiling patterns can span specific seasons or timeframes. An optional underwater inductive modem provides real-time...

Valeport fastCTD Profiler

Valeport’s fastCTD Profiler is designed to deliver high-quality CTD casts at rapid drop rates. Created for coastal and oceanographic profiling, this profiler is an evolution of Valeport’s popular miniCTD instrument. The system incorporates Valeport’s world-class technology to allow the fastCTD Profiler to deliver the highest-quality profiles in a lightweight and robust package. The fastCTD Profiler uses a conductivity cell designed for optimum flow-through, a high accuracy, fast response thermistor temperature sensor and a 0.01% pressure sensor synchronously sampling at up to 32Hz to attain the most accurate measurement data. Completely programmable, no data is logged until the programmed trigger depth... (read more)

Underway Sound Velocity Profiler

Building on the success of the UnderwayCTD system, Oceanscience has partnered with Valeport (UK) to develop an Underway sound velocity (SV) profiling system. The UnderwaySV system includes the new Valeport RapidSV ‘freefall' sound velocity profiler, allowing hydrographic surveyors the opportunity of fast, high quality SV profiles without ever having to stop a ship and suspend survey operations. The system offers a predictable tow path allowing it to be used when other equipment is being towed. This approach to sound-speed profiling is aimed at the hydrographic survey market, where stopping a ship for a sound-speed profile means significant loss of active... (read more)

Multi-Frequency Acoustic Doppler Profiler

Built to easily collect data in the most extreme flood and drought conditions, the next-generation Sontek/YSI RiverSurveyor S5 & M9 are used to collect velocity profiles, depth, and discharge data in canals, rivers and streams. It combines three instruments into one. Multiple acoustic frequencies fused with precise bandwidth control make for the most robust and continuous shallow-to-deep channel measurements ever. Leading technologies such as Bluetooth, spread spectrum radio, and RTK (Real-Time Kinematic) GPS are all incorporated to elevate performance and expand utility. With a press of a button on a mobile device, or from the convenience of... (read more)

WESP: Water and Strand Profiler

Vehicle for bad-weather and wave-zone survey

The Netherlands is bordered in the north and west by the North Sea. Twenty-six percent of the country’s landmass lies below sea level. Global warming will bring slow rises in sea level, whilst extensive draining off in the west of The Netherlands is resulting in a fall in ground level. Given this background it is easy to understand why one of the main goals of the Dutch government is to protect the country against floods. Here knowledge and insight is required regarding several morphological processes pertaining to the Dutch coast. Such knowledge is acquired by means of coastal studies; quantitative... (read more)

Turbulence Profiler for Bergen University

Rockland Scientific, Canada, has been awarded a contract to deliver a VMP-250 Turbulence Profiler to the University of Bergen, Norway. The VMP-250 system includes a buoyancy collar and remote-controlled weight release mechanism, allowing the profiler to be operated in an uprising configuration. University of Bergen researcher Dr Ilker Fer, will deploy the VMP-250 during the Arctic summer 2014 to measure turbulence and mixing under drifting sea ice, as part of the project "On Thin Ice: Role of Ocean Heat Flux in Sea Ice Melt” funded by the Research Council of Norway. The objective of the project is to study the... (read more)
