China's manned submersible "Shenhai Yongshi" (Deep-Sea Warrior) arrived in the westerlies at 37 degrees south latitude. The westerly belt is known for its strong winds and huge waves. It caused great difficulties for the submersible to dive. It will rely on frogmen to pick off and hang riggings manually against the turbulent sea waves and winds. The work of the frogman is hazardous, but it is of prime importance to guarantee the successful diving of the submersible.
