The Story of Autosub
To the Arctic - Courtauld Glacier
In 2004, Autosub undertook two cruises aboard RRS James Clark Ross in the Arctic. Wings were added to the rear half of the centre section of the vehicle to improve surface diving. Also added was an Aqualab water sampler, a 200ml motorised syringe taking in water and saving into one of 25 50ml bags. Conditions were more often mist and fog, with sunny days being the exception.
Autosub successfully executed several under sea ice missions. The vehicle was fitted with two semi-transparent acoustic ‘windows’ which covered the upward-looking Kongsberg EM2000 swath bathymetry transducers.
