A more thorough explanation:

Definition: Ligen is a noun that refers to goods that are abandoned at sea but attached to a buoy so that they may be recovered. It is also used to describe wreckage or cargo lying on the seabed.

Examples:

• A fishing boat found a ligen floating in the water and was able to recover the goods.
• The divers explored the ligen on the seabed and found some valuable artifacts.

The examples illustrate how ligen refers to goods or wreckage that are found in the sea. In the first example, the goods were attached to a buoy, which is a common practice to make them easier to recover. In the second example, the ligen was on the seabed, which can make it more difficult to retrieve.
