Suitability Study of Survey Equipment Used in the MODUM Project

Modern seafloor mapping techniques are based almost entirely on acoustics systems. With the usage of appropriate equipment, it is possible to examine seabed in terms of its morphology and also sub-bottom structures. Moreover, detection of objects placed on the bottom surface and buried in sediments is possible with proper gear as well. Above-mentioned actions were one of the crucial aims of the MODUM project (Towards The Monitoring Of Dumped Munition Threat). To achieve it, surveys with certain selected acoustic equipment were done together with data processing. The aim of this chapter is to present those systems, its possibilities, principles of working and results obtained thanks to it. Three different side scan sonar systems are described: used for seafloor surface scanning and detecting objects on it. Also, a sub-bottom profiler, which allows looking on seabed structures and detecting buried targets within, is presented. Additionally, a findings validation device, which is the remotely operated vehicle, is characterized in this chapter as well. Cooperation of all these systems gave good results in terms of detecting sunken munition in the Baltic Sea.
