Highlights

  • Five beams for mean currents and turbulence
  • Wave height and direction
  • Very small size and weight

Overview

  • The Signature1000 ADCP is the optimal tool for turbulence measurements. With a maximum sampling frequency of 16 Hz, it gives the scientific community an unprecedented opportunity to study a part of the turbulence spectrum that has never been accessible before. Vertical resolution current profiles of 2 cm over a range of up to 8 m further increase the Signature1000’s versatility, as does its ability to measure wave height and direction. The center beam also functions as a biological echosounder, enabling high-resolution measurements of biomass in the water column.

Applications

  • Turbulence studies
  • Sediment transport studies
  • 3D profiling using a wire walker
  • Surf zone dynamics
  • Studies of tidal currents
  • Fine-scale mixing studies
  • Vessel-mounted coastal surveying
  • Directional wave measurements
  • Coastal studies
  • Suitable for wave buoys
