The Sea-Wing7000 underwater glider, developed by the Shenyang Institute of Automation, CAS, is an instrument platform designed to glide to depths of 7000 meters for the application of deep-sea environment variables observation. Similar in structural layout to the “Sea-Wing” glider[1], to achieve these depths, The “Sea-Wing7000” using composite of carbon fiber / resin as the pressure hull. A “Sea-Wing7000” was deployed in February 2017 in the Mariana Trench, diving to a maximum water depth of 6329 meters. The “sea-wing7000” Mainly includes buoyancy regulating system, attitude regulating, Electronics, Moveable Battery Pack, pressure hull, CTD and other attachments. This paper describes the “Sea-Wing7000” development and experiments.
