Seeburg (dpa / sa) - The search for archaeological treasures on the bottom of the Süßen See near Halle began again on Monday.
The research ship “Sonara” of the Central German Engineering Consultancy (Midi / Halle) will use the most modern measuring technology to search for artefacts for a week and thereby map the entire lake bed in 3-D.
"We hope for many new and detailed findings," said project manager and underwater archaeologist Sven Thomas.
A rock formation in the middle of the lake is of particular interest, says Thomas.
There could be a 3500 year old Bronze Age barrow at a depth of about five meters.
For the first time, a sediment sonar is used which, under favorable circumstances, can penetrate the subsurface with sound waves up to two meters deep.
The objects hidden in the ground are recorded with sharp contours and can then be visualized on the computer in layers, as it were, said Thomas.
"This prepares excavations and the deployment of divers."
The exploration trip is already the sixth diving mission in recent years.
The first photos clearly show that the stones follow the Bronze Age «burial mound architecture», the most important evidence of this is a stele, a so-called guard stone and flat foundation stones that delimit the complex from the outside.

The sweet lake dried up several times in the course of its history.
There are remains of a lagoon in front of the Carolingian settlement of Wormsleben around 800. There are also remains of buildings and footbridges under water with lengths between 20 and 50 meters from the 11th to 15th centuries.
"The research project has received tremendous support from many enthusiasts, sailing enthusiasts and local residents, and has been baptized with the non-scientific but memorable name of 'Malandis'," said Thomas.
The M stands for Mansfelder Land and is based on the "Atlantis".
