R421 Underwater Investigations

Mock Shipwreck Mapping Exercise


In October 1997, students in the R421 Underwater Investigations class within the Underwater Science program participated in an underwater mapping exercise. Artifacts were placed in a shallow (5' depth) pool, oriented in such a way as to resemble a shipwreck with associated components. The task was then to accurately measure the artifacts and make a site plan, implementing SCUBA gear, tape measures, and underwater slates.

Linked below is a site plan developed by part of the class, as well as a demonstration of utilizing PIT (Photographic Imaging Technique) to the same site plan.
