Oceanography

Aquadopp 2

6000 m

High-performance full ocean depth, single-point current meter with titanium housing

  • Single-point current meter capable of measuring at full ocean depth
  • Titanium housing
  • Diagnostics mode for mooring performance evaluation

Overview

With all the features and capabilities of the standard Aquadopp, the deepwater Aquadopp 6000 m current meter has been used and proven by oceanographers around the world for almost 20 years. Thanks to innovative data diagnostic features for challenging environments, it provides exceptionally high-quality 3D currents in a form factor that is easy to install in any type of mooring line configuration, or simply attached to a bottom or surface platform.

The 6000 m Aquadopp now offers 6% broadband measurements and “hibernation mode” between measurements, enabling precise data collection with lower power consumption. The upgraded deepwater Aquadopp design also offers increased internal battery storage, extending potential deployment duration.

  • Currents

Highlights

  • Single-point current meter capable of measuring at full ocean depth
  • Titanium housing
  • Diagnostics mode for mooring performance evaluation
  • LED blinks when pinging for peace of mind during deployment

Usage

  • Studies of deep-water currents
  • Attached to mooring lines
  • Combined with riser monitoring systems
  • Near-bed current measurements from landers

Setup

Nortek deployment software allows users to customize their 600m Aquadopp deployment in a straightforward manner, providing guidance on deployment schemes, battery power and required internal memory.

Deployment

The 6000m Aquadopp is the ideal current meter for deep-water moorings. The instrument is capable of very long-term, unsupported deployments thanks to its low power consumption, internal data collection and ability to run entirely on internal battery power.

Data

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