landscape reconstruction and anthropogenic (harbour) structures. Regarding the landscape reconstruction glacial channels,
silted-up back waters of rivers and former coastlines can be detected by land seismics and dated with the help of
corings. Appropriate results were achieved e. g. in Ralswiek on the island of Rügen, near a Roman fort in Kalkar and
in Leiruvogur on Iceland. In marine areas high-resolution stratigraphy can be achieved by marine reflection seismics as
shown for example in Bonn and Ainos. Especially for magnetics our systems were adjusted to the conditions in the transition
zone. Now measurements can be conducted in shallow water, flooded areas (water depth < 10 cm) and in rough
terrain to map settlement and harbour structures. Magnetic measurements covering land, flooded areas and shallow
water done in Ainos, Turkey, revealed probable harbour constructions. A magnetic sledge allowed measurements in
high grass on Iceland. A problem in the transition zone is the high electrical conductivity of soils that anticipates the
use of GPR and ERT and its associated depth resolution in near surface regions. A solution of this problem might be
seismic surface waves methods that are independent of electrical conductivity.
