Reporter today (3 days) learn from rich ministry, came 26 days on August 20 local time, the Chinese silver dollar that approving in executive rich ministry of task of 48 the number of voyages or flights " ocean " on the boat, by our country of own research and development " sea otter Ⅲ " unmanned cable accuses submersible (ROV) deep-sea submergence is carried out successfully 5 times in area of seamount of northwest Pacific Ocean, the biggest go deep 4200 meters, finish 22 times in all sit bottom, hover 36 times observation, close bottom observation works 16 hours, the environment that finished typical seamount investigates the task.
According to introducing, this " sea otter Ⅲ " begin operation of division take an examination ofing 5 times, collect sponge in all, add up to end of branchial eel, encrinite, sea snake, shrimp, coral 6 kinds of biology. Next, the scientist will undertake to these sample the lab studies, extend the understanding of diversity of pair of deep-sea seamount biology further, the similar sex that knows community of the biology between different seamount and connect quality. Additional, "Sea otter Ⅲ " collect sample of case of n/med tuberculosis, bear in all 6.5 kilograms, through indoor chemistry composition is analysed, can understand its tantalum composition, and " grow " the history.
As we have learned, "Sea otter Ⅲ " it is first 6000 rice level of domestic current operation ROV, deploy manipulator of 7 functions, 5 functions, grand sample chamber suction type, rock cut machine, deposit is protected press the facility such as sample chamber; Sonar is inspected before embarking, exceed the special type tool such as short base line, have avoid automatically let ability of fraise, deep-sea position; Additional of 11 high-definition photograph contented like the head deep-sea observation, film like the function; 7 airscrew reach hydraulic pressure system, assure ability of Sunday run cruise. "Sea otter Ⅲ " ROV system is experimental applied success, it is important to indicate equipment of deep-sea and great technology developed an our country to be stridden ahead again one pace. "Sea otter " ROV system is our country " flood dragon Long Tanhai " one of the project serious content, believe to will appear very quickly in development of deep-sea resource perambulate, deep-sea environment to monitor the numerous domain such as protection, deep-sea scientific knowledge, the our country that help strength achieves goal of strategy of marine powerful nation.
