High definition cameras from Norwegian high-tech company Kongsberg Maritime were used in a recent expedition of China’s manned deep-sea submersible Jiaolong to the Mariana Trench in the western Pacific Ocean.
The Jiaolong had been equipped with two ultra deep water versions of Kongsberg Maritime OE14-502D High Definition Cameras along with an ultra deep OE14-208 Digital Stills Camera and two OE14-364 Compact Fixed Colour Cameras. The Jiaolong made a total of six dives altogether, reaching a depth of 7062 meters on its final dive. This surpassed a national record depth of 7020 meters reached just a few days previously.
While at the ocean bottom, scientists captured high quality video, conducted geological surveys, placed markers and gathered samples of organisms living on the ocean bed.
In a company press release, Kongsberg Maritime says the HD video footage is the deepest recorded using KONGSBERG HD cameras. This, along with numerous past deep water marine research applications around the globe where KONGSBERG cameras have been used in depths in excess of 8000 meters, demonstrates KONGSBERG’s ability to manufacture the most rugged harsh environment underwater cameras available.
