Gliders Successful During Proud Manta 11

NURC -

From 24 January to 11 February, in the Ionian Sea to the southeast of Sicily, three gliders participated for the first time in an anti-submarine warfare (ASW) exercise.

During Proud Manta 11, NURC--a NATO Research Centre in La Spezia--successfully used the gliders to collect in situ, three-dimensional environmental data to support improved operational planning and decision-making tools.

As opposed to traditional propelled autonomous underwater vehicles (AUV), gliders use shifts in mass to steer and changes in buoyancy to dive and surface, and can stay at-sea for very long periods of time.

Thanks to the Italian Navy, two shallow-water gliders (called by scientists Greta and Zoe) and one deep glider (named Noa) were deployed from the Italian Navy vessel Levanzo.

For 18 days the gliders operated autonomously, sending data every three hours through an Iridium satellite link back to a command and control room at NURC.
