原文：

Last week an Indonesian submarine cruised through the Lombok Strait between the islands of Bali and Lombok to carry out routine testing. But in the early hours of April 21, the 44 year-old KRI Nanggala 402 submarine dropped out of contact and plummeted 838 meters to the ocean floor, taking 53 crew members with it. Indonesian military officials found the sunken vessel broken into three parts on the bottom of the Bali Sea.

While some speculated that the submarine was hit by a foreign missile or a power blackout, Indonesian authorities now suspect the submarine was pulled under by a powerful underwater current called an internal solitary wave.

The ocean is in a constant state of motion with the rise and fall of tides, currents and waves. Waves don't just occur on the surface, they're also generated in deeper water. This is because the density of the ocean changes from the surface to the bottom of the sea floor -the colder the water gets, the more dense it becomes.

中譯：

1艘印尼潛艦上週於峇里島與龍目島之間的龍目海峽巡航，實施例行測試任務。惟於4 月 21 日凌晨，這艘艦齡44歲的「神鋤號」失聯，與艦上53名成員，一併沉墜至838公尺深的海床。印尼軍方官員在峇里海底部找到了這艘沉沒斷成3截的潛艦。

儘管有人臆測該潛艦係遭他國飛彈擊中或是電力中斷，印尼有關當局目前懷疑，這艘潛艦係遭一種稱為「內孤立波」的水下強大海流拖下海底。

海洋有潮起與潮落、有海流也有波浪，係處於一種恆動的狀態。波浪不光是發生在海面上，也會在較深的海中生成。此係由於海洋的密度從海面到海床底部都會產生變化─海水愈冷，其密度亦隨之變高。（第9篇／共14篇）
