SVP – Surface Velocity Drifter

An air or ship deployable surface drifting buoy, designed to measure currents 15m below the ocean surface. Data is transmitted regularly using either Argos or Iridium satellite communication.


Surface Velocity Drifter

The MetOcean Surface Velocity Program (SVP, iSVP) drifting buoy is a Lagrangian current-following drifter, designed to track water currents 15 metres below the ocean surface. Developed for unattended operation in the worlds oceans, the drifter consists of sensors to acquire meteorological and oceanographic data, a battery power source and a satellite transmitter that relays the data through either Argos or Iridium® satellite systems.

Additional Sensors

The holey sock drogue is centered at 15 meters and is sized to provide a drag ratio (drogue frontal area to that of all other submerged frontal areas) in excess of 40:1. A basic unit is equipped with a sea surface temperature sensor. Additional sensors can be added to the SVP including: barometric pressure (BP), salinity, and conductivity. The SVP buoy has been a proven data collection asset for the oceanographic, meteorological, and oil and gas markets. Today, major weather forecasting agencies use MetOcean drifting buoys and they are found throughout the world’s oceans.

Polar iSVP

A iSVP for polar specific applications is available, designed to track and monitor ice flow movement, and provides the user with essential real-time barometric pressure and GPS positional data. The Polar iSVP does not feature a 15m drogue as it is designed to be deployed directly on ice. The Polar iSVP is also available in an air-deployed configuration for use in highly remote locations.
