The Signature VM Coastal safeguards data quality, opens up new and unprecedented opportunities to the scientific community, and offers operational convenience and reduced complexity.
The Signature VM Coastal package includes the Signature1000, 500 or 250, allowing for great versatility in both the vessel-mounted and bottom-mounted configurations. By using a state-of-the-art and user-friendly vessel-mounted package, measurement errors and initial installation time can be greatly reduced.
Applications
- Coastal surveys, up to 200 m depth
- Port and harbor mapping
- Studies of tidal currents
- Sediment transport studies
- Large-scale mixing studies
Signature VM Coastal - 1000kHz
Fast pinging AD2CP for current measurements and high-resolution echograms in shallow water [30m]
Overview
The Signature VM Coastal 1000 kHz is an optimal instrument for smaller navigational rivers, estuaries and shallow coastal zones. The 16Hz ping rate permit concurrent measurements of current, depth, bottom track and water column echograms.
Echograms are measured with cm resolution down to the bottom, a common area with high suspended sediment load and where a standard VM-ADCP is not able to measure.
Obtaining data from a compact vessel or USV in a river or near shore environments can be challenging due to sudden accelerations, course changes or wave induced motion. The true heading GNSS time server and the optional AHRS accommodate to extend the operational limit.
Coastal or river surveys are mostly transient installations. The compact VM-ADCP is convenient to be used on each vessel or USV. By using a state-of-the-art and user-friendly vessel-mounted package, measurement errors and initial installation time can be greatly reduced.
Highlights
- A coherent system that is quick and convenient to operate
- Fifth echosounder beam for sediment measurements down to the bottom
- Simultaneous current and depth information in one place
- High (16Hz) ping rate for profiling from smaller dynamic platforms and turbulent environments
- Ethernet ADCP and GNSS timeserver, offering tight network timing
- Optional AHRS for improved tilt compensation in dynamic environments
- Outstanding bottom-track performance [30m]
Applications
- Medium size USV's and manned vessels
- Navigational rivers, estuaries and coastal surveys, up to 30 m depth
- Current or turbulence studies
- Sediment transport studies
- Biomass studies
- River discharge studies using Qrev
- Studies of tidal currents
- Condition monitoring
Signature VM Coastal - 500kHz
Fast pinging AD2CP for current measurements and high-resolution echograms in the littoral zone [70m]
Overview
The Signature VM Coastal 500 kHz is the right instrument for the larger navigational rivers up to coastal surveys. The 8Hz ping rate permits concurrent current measurements, depth, bottom track and water column echograms.
Echograms are measured with cm resolution down to the bottom, a common area with high loads of suspended sediment and where a standard VM-ADCP can't measure.
Obtaining data from compact vessels in large rivers or coastal environments can be challenging because of sudden accelerations, course changes or wave induced motion. The true heading GNSS time server and the optional AHRS can widen the operational limits.
The 70m bottom track range safeguards a proper velocity correction even in difficult conditions.

Signature VM Coastal - 250kHz
Fast pinging AD2CP with range for vessels operating on the continental shelf [200m]
Overview
The Signature VM Coastal 250 kHz grants precision, a high ping rate and range for those who want to cover the continental shelf.
By using a state-of-the-art and user-friendly vessel-mounted package, measurement errors and initial installation time can be greatly reduced.
Coastal seas can be a challenging environment to work in. Besides the true heading GNSS time server, the optional AHRS can widen the operational limits. The 200m bottom track range safeguards a proper velocity correction even in difficult conditions.
Highlights
- A coherent system that is quick and convenient to operate
- 3Hz ping rate for profiling from coastal vessel and environments
- Ethernet ADCP and true heading GNSS timeserver, offering tight network timing
- Optional AHRS for improved tilt compensation in dynamic environments
- Outstanding bottom-track performance, even in difficult conditions [205m]
- Optional 5th beam for current and wave measurements in stand-alone mode
- Increased pingrate & range, yet delivering the same accuracy alike slight higher frequency instrumentation on the market
Applications
- Large size offshore USV's and manned vessels
- Estuaries and deep coastal surveys, up to 200 m depth
- Current or turbulence studies
- Sediment transport studies
- River discharge studies using Qrev
- Studies of tidal currents
- Condition monitoring
