underseal

Underseal is a term used in the context of underwater archaeology and maritime history to describe a type of seal or stamp that is applied to an object underwater. This technique is often used to mark or authenticate artifacts, documents, or other items that are submerged or recovered from underwater environments. Underseals can be made from various materials, including metal, glass, or even stone, and may bear inscriptions, symbols, or images that provide information about the object's origin, date, or significance.

The process of applying an underseal involves submerging the seal and the object to be marked in water, then using a tool to press the seal onto the object. This method ensures that the seal is applied in a controlled environment, minimizing the risk of damage to the seal or the object. Underseals are commonly used in the preservation and authentication of underwater artifacts, as they provide a permanent and visible record of the object's history and provenance.

In some cases, underseals may be used to mark objects that are intended to be submerged or buried, such as time capsules or memorials. These underseals can serve as a form of documentation, providing information about the object's purpose, contents, or the intentions of those who created it. The use of underseals in underwater archaeology and maritime history has contributed to the preservation and understanding of our shared cultural heritage, allowing us to learn more about the past and the people who came before us.
