GEOMAR Technologie GmbH - GTG

In summer 1997 GEOMAR Technologie GmbH (GTG) was surveying the coastal and harbour areas of Beirut and Tripoli in the Lebanon. A total area of more than 250 hectars was surveyed within eight days. The surveys were carried out to achieve basic data for planning and building activities of the harbours and for reclamation of land from the sea within the coastal area.

The surveyed areas are marked as hot spots; there is no link, but just a display of the name of the surveyed area. The picture kindly was made available by MAPS geosystems.

Main task was the geophysical survey and data evaluation to achieve information about the marine sediment. For the shallow waters subbottom profiling a side scan sonar system was used as well as a boomer system.
Additional interpretation and planning data are given due to the echo-sounding measurements and the mapping of the bathymetry. The depth rages from 4 to 45 meters. Contour lines of bathymetry with a 0.5 meter interval revealed in detail structures caused by bottom currents as well as by geology of the eastern Mediterranean Sea margin.
For precise horizontal positioning Differential Global Positioning (DGPS) was used.
