Working Tools Study for JiaoLong Manned Submersible

AbstractThe remarkable progress in deep submergence science with manned submersibles in the past 50 years has made it possible for us to directly explore the inaccessible underwater extreme environment. Basic research carried out at depths over 1,000 m in the deep ocean has
 provided dramatic and unique insights into some of the most compelling scientific questions ever posed. Deep research manned submersibles have been widely recognized as indispensable platforms for conducting deep-sea research. Whereas all deep-sea submersibles share the unique feature of direct
 observation function by scientists and pilots from the cabin, all manned submersibles are equipped with different tools to implement a wide range of jobs in different exploration purposes. These can directly affect productivity and each dive's outcomes, such that it would be meaningful to
 study the samplers, sensors, and other devices that have been installed on the different deep-sea research manned submersibles around the world. This article will also introduce the research and development status of the JiaoLong manned submersible's operational tools, which have been
 researched and tested during the sea trials and test operational phase over the past 9 years. Based on developed technologies, state-of-the-art tools are essential to achieve a high-efficiency use for each dive. The article brings forward discussion and suggestions for the development of JiaoLong's
 operational tools, followed by a conclusion from the perspective of JiaoLong's operation team.
