Secrets of Malta's Historic Water Systems06/05/2008 |
| Miniature sonars, engineered by Tritech International, have been invaluable in helping to uncover the deep secrets of Malta's historic fresh water systems. Several reservoir sites in Malta and Gozo have been the focus of collaborative archaeological explorations by AURORA Trust, Marine Resources Development Foundation and California Polytechnic State University. The investigations aim to understand the complexities of underground cisterns and infrastructures and to research their evolution. |

Sonar data and video images were collected through a 250ft cable, attached to a control box and computer at the main access points. Project investigator, Christopher Clark, from the California Polytechnic State University, said that the Tritech sonar was ideal for their mapping application for two reasons. Firstly, there were fewer false reflections and much less noise than he expected. Secondly, the compact size of the sonar allowed the ROV to fit through tight passages that were not accessible when using other sensors.
Six of the sites visited were mapped using mosaic and robot Simultaneous Localisation and Mapping (SLAM) algorithms.

MCA on Surveying the British Coast |
Rob Spillard explains how the MCA is conducting hydrographic surveys, including the history of British hydrographic surveying, latest developments in technology and wreck research projects, sometimes accompanied by a BBC TV camera crew. This movie includes an example of the discovery of two sunken WWI submarines off the Orkney Islands.
