Description

AUV mission 009 from NBP1902.
The mission went partway (0.6 km) underneath Thwaites glacier.

AUV mission 011 from NBP1902.
The mission went partway (3 km) underneath Thwaites glacier.

The autonomous underwater vehicle 'Ran' is a Kongsberg Hugin AUV depth-rated to 3000 m. It is equipped with a Honeywell Hg9900 inertial navigation unit, aided with Nortek 500 kHz upward- and downward-looking doppler velocity loggers (DVL). Navigation was also aided by deploying several underwater transponders (UT
