What Does Hydroscopy Mean?
Hydroscopy is the practice of viewing objects underwater. Hydroscopy uses an instrument known as a hydroscope, which is typically constructed out of a tube with a transparent material (e.g., glass, plastic) inserted into it that allows for observation.
Hydroscopy has many uses. It is often used for scientific discovery of new underwater plant and animal species and to exam the behavior of aquatic organisms. Hydroscopy is used to view underwater pipelines and ship hulls to look for the presence of corrosion. Hydroscopy is also used to survey the floor of a body of water.
