Mag648 in underwater glider application

May 25, 2012 - via Bartington Instruments

Bartington Instruments’ low noise Mag648 magnetometer is being used to assist underwater gliders in navigating beneath the icecap.

Underwater gliders are used for environmental monitoring and can operate autonomously, but must surface periodically to reorientate themselves with a GPS signal. When the sea is iced over this becomes problematic.

A team at Memorial University, Canada has developed a system that allows underwater gliders to build up a map of magnetic anomalies on the seabed during the ice-free summer months. The glider will then use the map to navigate underwater once the sea has iced over again.
