Nortek Signature VM Ocean - 100|75/55 kHz ADCP

The Signature VM package delivers vessel-mounted current profiler AD2CP capabilities based on present-day technology

Nortek’s vessel-mounted ADCP current survey package – called Signature VM – opens up new and unprecedented opportunities to the community, while offering operational convenience and reduced complexity. Data quality can be safeguarded, and both errors and initial installation time can be substantially reduced by using an integrated system where each is module is pre-qualified.

Description

Signature VM Ocean - 100kHz

Vessel-mounted ADCP capabilities with an optional scientific echosounder for biomass measurements into the mesopelagic zone [300-400m]

 

Overview

Nortek’s vessel-mounted Signature VM Ocean (100 kHz) opens up new opportunities to measure currents and to study biomass simultaneously.

Until now, epipelagic and upper mesopelagic VM ADCP surveys could not deliver the resolution, precision or range to examine the ocean boundary layer in detail. To study biomass in the upper-ocean boundary layer, you had to add a separate scientific echosounder.

Modern people desire state-of-the-art tools that are coherent and convenient to operate. The Signature VM Ocean 100 kHz grants access to current and echogram measurements to non-daily users as Ph.D.'s, biologists or offshore engineers.

Highlights
  • A coherent and modern system that is convenient to operate
  • Four beams for current profiling with a range between 300-400m
  • Optional scientific echosounder with multiple modes for biomass measurements
  • Modern graphical interface with current and range corrected echogram
  • Outstanding bottom-track performance [560m]
  • Automated post-processing of day files
  • Ideal for ocean USV's due to low power requirements
  • Optional GNSS timeserver, offering tight Ethernet network timing and true heading information
  • Optional AHRS for improved tilt compensation in dynamic environments
  • VM or stand-alone applications
Applications
  • Large size offshore USV's and manned ocean vessels
  • Ocean surveys
  • Offshore operations
  • Current or large scale turbulence studies
  • Internal wave detection
  • Upper-ocean boundary-layer studies
  • Detection of fish, krill or plankton in the water column
  • Studies of tidal currents
  • Condition monitoring

 

Signature VM Ocean - 55kHz

Dual-frequency long-range vessel-mounted ADCP capabilities covering the mesopelagic zone [up to 1000m]

 

Overview

The Signature VM Ocean 55 kHz is a dual-frequency profiler that combines high-resolution profiling and long-range profiles into one instrument opening up opportunities for physical oceanography, biologist and marine engineers.

The novel piston transducer design empowers a high single ping precision which is crucial in obtaining long-range data from moving platforms. Options as a true heading GNSS timeserver will further complement the ADCP data.

The convenient to use and modern software turn long-range current measurements at hand to non-daily users as Ph.D. students, biologists or operational engineers.

Recorded files can automatically be processed for a concise overview of the day.

Highlights
  • A coherent and modern interface that is convenient to operate
  • Piston transducer design bringing high single ping precision
  • Three beams for current profiling operating on 75 or 55 kHz
  • Detailed boundary layer up to 675m (75 kHz) and coarse long-range profile up to 1000m (55 kHz)
  • 6m fine to 20m coarse resolution
  • Outstanding bottom-track performance [1000m]
  • Automated post-processing of (day) files
  • A relative light weight and compact AD2CP for VM and stand-alone applications
  • Ideal for ocean USV's due to low power requirements
  • Optional true heading GNSS timeserver, offering tight Ethernet network timing and true heading information
  • Optional AHRS for improved tilt compensation in dynamic environments
  • VM or stand-alone applications
Applications
  • Large size offshore USV's and manned ocean vessels
  • Ocean surveys
  • Offshore operations
  • Current or large scale turbulence studies
  • Internal waves
  • Deep ocean studies
  • Studies of tidal currents
  • Condition monitoring
