AWAC (Acoustic Waves and Currents)

The Nortek Acoustic Waves and Currents (AWAC) sensor is a current profiler and directional wave system in one unit. The AWAC is well suited for both autonomous data collection and as part of a real-time data telemetry system. Subsurface deployment means the instrument is always protected from harsh weather, vandalism, and ship traffic. The small, yet rugged instrument is suitable for multi-year operation in tough environments. Plastic and titanium parts avoid corrosion. The AWAC is available in three transmit frequencies for operational ranges spanning 2m - 100m.

ADCP (Acoustic Doppler Current Profilers)
Current profilers measure current speed and direction in multiple layers throughout the water column.
Shallow water current profilers can both measure the currents and the wave height / direction for engineering applications.

Workhorse Sentinel ADCP (RD Instruments)
The self-contained Workhorse Sentinel ADCP is Teledyne RD Instruments' most popular and versatile acoustic Doppler current profiler (ADCP) configuration, boasting thousands of units in operation in over 50 countries around the world.
By providing profiling ranges from 1 to 165 m, the high-frequency Workhorse Sentinel ADCP is ideally suited for a wide variety of applications. The Workhorse Sentinel also offers unbeatable precision, with unmatched low power consumption, allowing you to collect more data over an extended period.
The lightweight and adaptable Workhorse Sentinel is easily deployed on buoys, boats, or mounted on the seafloor. Real-time data can be transmitted to shore via a cable link or acoustic modem, or data can be stored internally for short or long-term deployments. The Sentinel is easily upgraded to include pressure, bottom tracking, and/or directional wave measurement - for the ultimate data collection solution.

The Oceanscience UnderwayCTD provides research grade CTD (conductivity, temperature, and depth) profiles while underway at up to 20kts. The unique freefall profiler offers researchers vertical profiles even as the ship is moving away from the deployment location. The innovative deployment winch and re-spooling mechanism allows the probe to be recovered and re-launched time after time without ever needing to stop or slow down. Profiles are gathered quickly, allowing excellent spatial resolution for CTD transects. The UnderwayCTD can be installed on practically any vessel. The small footprint winch can be mounted on a post or rail, and can be set up and operated by one person. The UnderwayCTD components can be transported from ship to ship with ease, making the system ideal for gathering high quality data from vessels of opportunity.
CTD Profiling from a moving vessel
  • Achieve over 500m vertical profiles while underway at 10 kts.
  • Convenience of expendables without the environmental impact.
  • High quality SeaBird Electronics free fall CTD data.
  • Compact and portable for deployment on multiple vessels.

Trimble SPS855 GNSS Modular Receiver

The Trimble® SPS855 GNSS Modular Receiver is simply the most advanced construction modular receiver on the market. Its position-only or position and heading capability set it apart from the competition. Its ease of configuration and use as a base or rover, and its choice of antennas make it truly universal - capable of any operation.

The SPS855 combines the radio and GPS receiver in a single housing. You can secure the majority of your investment inside a site trailer, vessel cabin, or carrying case, protected from the elements and/or theft, leaving only the antennas outside.

Available in a range of options to suit your individual applications, flexibility and performance requirements, versatile Trimble GNSS receivers are a future-proof investment. The SPS855 uses all currently available satellite signals including L1, L2 and the GPS modernized L2C code. It can be upgraded with GLONASS and L5 GPS signals to optimize performance in areas of tough GPS-only conditions and maximize your investment well into the future.

It is also part of a larger family of receivers that have the same user interface, the same accessories and the same workflows, allowing multi-unit fleets to be created with interchangeable components.

Trimble SPS361 Modular GPS Heading Receiver

Trimble SPS361 Modular GPS Heading receivers are ideal for the following site development and marine construction applications:

  • RTKroveronsitevehicleormarinevesselsthatrequirepositionandheading
  • Site and marine rover applications using Location GPS augmentation, including OmniSTAR, Location RTK, SBAS, Beacon, and DGPS RTCM

The receiver has a keypad and display, so you can configure the receiver without using a controller or computer. All the receivers can optionally record GPS data to the internal memory, and transfer the data over a serial or Ethernet connection.
