What are drifters and drogues?
DRIFTERS are oceanographic instruments that are composed of a surface float tethered to a drogue. They provide essential information on the upper ocean such as temperature, salinity, current direction, and speed.
> Learn more about drifter types
A DROGUE is an essential component of a water-following device. It consists of a carefully designed sea anchor that ensures the drifters follow the water with high accuracy. Surface waves that frequently exceed amplitudes of several meters and the wind blowing at the surface of the ocean do not affect it.

Technology Development and Custom-Made Drifters
The Lagrangian Drifter Laboratory innovates drifter and sensor designs as demanded by science applications and evolving requirements.
Drifter Types
Nine standard drifter types are available immediately for deployment.
Drifter-Based Science Products
Drifter arrays complement the ocean observing and modeling components of science programs. The LDL provides analytical products that support programs’ research objectives.
Subscription Service
To meet scientific and operational needs, custom sensor/drifter packages that fit within the Global Drifter Array can be deployed on a subscription basis to collect additional ocean variables.
