Overview
With all the robust and easy-to-use 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.
See the details of the Generation 2 Aquadopp updates in the release notes here.

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.
