    Description: Seismic survey of the silted bays of the Medione and Gorgo Cotone rivers. Evidence of the location of the harbour of the ancient city of Selinus, Sicily. The ruins of the ancient city of Selinus are located on the southern coast of Sicily on a limestone plateau bounded to the east and west by two respective silted bays or riverbeds. So far it has been impossible to archaeologically determine which of these bays served as a harbour in antiquity. In order to explore the depth structure of the silted bays, we performed two seismic surveys with shear waves, reaching penetration depths of approximately 25 m. The seismic measurements were calibrated by drillings. In th upper 15 m, the two bays differ strongly in seismic structure. The eastern bay (Gorgo Cotone valley) must be considered as a former lagoon that was connected to the sea. When the city of Selinus was founded, this lagoon was already silted at its shore, and it was banked up artificially for the construction of the eastern city quarter up to the city wall. The western bay (Modione valley) shows uniform fluvial sedimentation. A possibly artificial banking can also be found at the western foot of the city hill, dipping steeply (∼20°) from the city wall down to the Modione valley. The comparison of both locations shows that the eastern bay is a more plausible location of the harbour of Selinus, due to its protected lagoon and remains of construction.

    Description: The lowland of the Oldenburger Graben was investigated in an interdisciplinary cooperation between Geologists, Archaeologists and Palaeobotanists. The postglacial sea level rise was reconstructed by combining and evaluating different methods and results. A new preliminary shoreline displacement curve for the south-western Baltic was created on the basis of reliable sea level data from adjacent regions. The shoreline displacement curve for the Oldenburger Graben mainly covering the time interval from 5100 to 3000 BC cal suggests an oscillating sea level rise. Two periods of intensive sea level rise can be distinguished from two periods of modest rise. The duration between two periods of intensive rise mounts up to 900 years. These oscillations correspond with climatic variations in the North Atlantic. The new preliminary shoreline displacement curve for the south-western Baltic reveals at least eleven oscillations during the last 9000 years.

    Description: Die quartärgeologische Entwicklung der Grube-Wesseker Niederung (Oldenburger Graben) wurde vor dem Hintergrund des postglazialen Meeresspiegelanstiegs rekonstruiert. Die letzte glaziale Überprägung der Niederung erfolgte am Ende des Fehmarn-Vorstoßes durch subglaziale Schmelzwassererosion. Im Spätglazial und frühen Postglazial war die Niederung durch Seen und vermoorte Senken geprägt. Um 6000 BC cal erreichte die Litorina-Transgression die glaziale Hohlform. Die Meeresspiegelmarken für den Zeitraum 5100 bis 3000 BC cal belegen einen phasenhaften Anstieg von -4,5 bis -1,75 m NN. Während dieser Zeit entwickelten sich zwei Ostseeförden. Besiedlungsspuren aus dieser Zeit sind häufig an Sand- oder Tillkuppen gebunden, die zur Besiedlungszeit Inseln oder Halbinseln darstellten. Die Aussüßung der Förden begann um 3000 BC cal bzw. um 2500 bis 2000 BC cal. Während der slawischen Besiedlung von Starigard/Oldenburg ist eine durchgehende Verbindung von der Mecklenburger Bucht bis zum Wesseker See denkbar. Die derzeit vorliegenden Ergebnisse zum Meeresspiegelanstieg in der südwestlichen Ostsee wurden zusammengestellt und teilweise neu bewertet. Auf Grundlage der als verlässlich bewerteten Daten sowie unter Berücksichtigung eines Zusammenhangs zwischen Temperaturschwankungen im Nordatlantik und dem eustatisch bestimmten Meeresspiegelanstieg in der südwestlichen Ostsee wurde eine neue Strandlinienverschiebungskurve für den Küstenabschnitt zwischen Flensburger Förde und Wismarbucht erstellt. Diese legt einen mindestens elf Oszillationen umfassenden Meeresspiegelanstieg während der letzten 9000 Jahre nahe.
