Oceanography

Signature1000

High-performance mean currents and turbulence, wave height and direction

  • 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.

  • Turbulence
  • Waves
  • Echosounder

Highlights

  • Five beams for mean currents and turbulence
  • Wave height and direction
  • Ice thickness and ice drift
  • Very small size and weight

Usage

  • Simultaneous current and turbulence studies up to 30m 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 Signature1000 ADCP, including current, wave and turbulence measurements.

Deployment

Teams of all sizes can successfully deploy the Signature1000 thanks to its small size (21.2cm height), as well as 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 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.
