Overview
The Signature 500 ADCP is designed for flexibility. It measures current profiles at up to 8 Hz sampling frequency. It can also measure direct vertical velocity profiles, wave height and direction, and acoustic ranging to ice. The center beam also functions as a biological echosounder, enabling high-resolution measurements of biomass in the water column. All these features can be combined using Nortek’s patented concurrent mode technology.

- Turbulence
- Waves
- Echosounder
Highlights
-
Five beams for mean currents and turbulence
-
Wave height and direction
-
Acoustic ranging to ice
Usage
-
Simultaneous current and turbulence studies at up to 70m range
-
Sediment transport studies or biomass estimates using optional scientific echosounder
-
Buoy-mounted measurements in high-energy areas with optional AHRS for motion correction
-
Wave measurements and ice monitoring using acoustic surface tracking (AST)
Setup
The Signature Deployment software guides users through setup to ensure even the most detailed concurrent measurement schemes are handled correctly and makes certain all users can fully utilize the capabilities of the Signature 500 ADCP.
Deployment
The Signature 500 offers dependable buoy and bottom frame solutions from Nortek and leading industry partners tailored for the instrument. Optional AHRS updated at the same rate as sampling improves motion correction during vehicle and buoy-mounted ADCP current and wave measurements.
Data
Ethernet and optional serial data communications makes retrieval of data quick and easy, including post-recovery download or real-time applications. Ocean Contour is a powerful postprocessing software created specifically for the AD2CP platform.
