Between the dates of February 28th, 2008 and March 6th, 2008, investigators traveled to several cistern sites across Malta and Gozo. The goal of this project was to obtain video and sonar data that will help archaeologists understand the evolution of water storage systems in Malta. The data obtained provides information that was previously unknown including the size, shape, and complexity of the cisterns.

To gain this data, a VideoRay MicroROV, or underwater robot, equipped with camera and sonar was used. The robot was lowered down chutes until submerged in water. From that point, the robot could be driven through the cistern via joystick. Of the many sites visited, 6 were mapped using various post-processing techniques including image mosaic, and robot Simultaneous Localization and Mapping (SLAM) algorithms.
