Abstract
Abstract The world of manned underwater vehicles (MUV) in 2013 counts a total of 95 active submersibles used for ocean research, tourism, and commercial, leisure, and security applications. The MUV industry safety record remains pristine, with not a single incident involving loss of life in over 40 years. The paper reviews the state and future directions for the world’s deepest ocean research submersibles. In 2012 and 2013, the world of deep research submersibles saw dramatic advances, reaching full ocean depth for the first time in more than 50 years. The record of the world’s deepest submersible held by Japan’s Shinkai 6500 , rated to 6,500 m depth, for almost 25 years was surpassed by China’s 10-year development project of the Jiaolong submersible, rated to 7,000 m. The Jiaolong successfully completed its multiyear testing program, achieving full design depth in June 2012. This record feat was eclipsed, however, by the surprise disclosure and full ocean depth dive by James Cameron’s Deepsea Challenger , diving to a depth of 10,908 m in the Mariana Trench just months earlier. This depth had not been reached since the historic dive of the bathyscaphe Trieste in 1960, and brings new energy for several national organizations to develop full ocean depth submersibles. There are today a total of 14 national and commercial submersibles capable of diving 1,000 m or deeper, offering a wide range of services. This also provides a global network of rescue capability with locations in the United States, China, Japan, Russia, France, Spain, Canada, and Portugal.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
