Ocean currents

Vector - 4000 m

Investigate 3D velocity in the bottom boundary layer down to depths of 4000 m

Overview

The Vector is a high-accuracy single-point current meter that is capable of acquiring 3D velocity in a very small volume at rates up to 64 Hz. It is widely used for sediment transport applications, small-scale turbulence measurements and coastal engineering studies. It has an excellent track record of delivering outstanding data quality in a variety of applications. This titanium version of the Vector is suitable for investigating deep-water currents down to depths of 4000 m.

  • Currents
  • Turbulence

Highlights

  • Small-scale turbulence
  • Sampling up to 64 Hz
  • Small sampling volume for measurements close to boundaries

Usage

  • Studies of bottom boundary layers
  • Studies of deep-water currents
  • Ocean engineering projects
  • Low flow measurements
  • Flux measurements
  • Deep ocean mining support

Setup

This 4000m-rated velocimeter is set up using the Nortek deployment software, where users can customize the sampling rate (up to 64Hz), sampling volume size and coordinate system, especially relevant with the cabled probe option.

Deployment

Designed for small-scale turbulence sampling or collecting measurements near boundaries and in deep water, the Vector velocimeter offers multiple probe options (fixed or cabled) making for very flexible deployment setups.

Data

The Vector provides precise, rapid velocity measurements from a very small sampling volume of water. Users can resolve small-scale turbulence events and measure in areas traditionally difficult for ADCPs.
