Oceanography

Aquadopp Profiler 1 MHz

500 m, Generation 2

Small and compact, with up to 25 m current profiling range; option for PUV wave measurements

  • Up to 25 m current profiling range
  • Optional right-angle head
  • Pressure-based (PUV) directional wave measurements

Overview

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 m. The 1 MHz version has a current profiling range of up to 25 m. Designed for simple yet powerful operation, this current profiler is packed with features used by engineers and researchers to enable accurate and effective hydrodynamic data collection in a variety of environmental conditions.

This instrument can also be used to perform river discharge measurements by River Insight.

  • Waves

Highlights

  • Up to 25 m current profiling range
  • Optional right-angle head
  • Pressure-based (PUV) directional wave measurements

Usage

  • Mean flow measurements with high focus on ease of use and simplicity
  • Projects with needs for both high-resolution and normal-range current measurements
  • Studies of tidal currents
  • Measurements of combinations of waves and currents
  • This instrument is used to perform river discharge measurements by River Insight.

Setup

The 1MHz Aquadopp Profiler, designed for current measurements up to a 25m range, is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements.

Deployment

Compact size and an optional right-angle head allow for very near-bed deployments, maximizing water column coverage in shallow areas. Teams of all sizes can deploy an Aquadopp Profiler successfully.

Data

Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
