Sub-project 1: Natural and Cultural Sciences Holocene

Objective of the age determination

The task of the geology sub-section for the Jade Bay initially comprises a detailed survey of the Holocene sediment distribution along a west-east trending traverse, running transversely to known channel structures in the subsoil. Along the traverse, pile-driven core soundings were sunk to a final depth of between 6 m and 14 m below ground level. The individual drilling locations correspond to the different depositional conditions assumed for the respective mudflat area: With boreholes in the mudflats north of Dangast, in the subsoil of which a geest projection was mapped, in the Stollhammer Mischwatt, located near the former Oberahn fields and in the area of the former channel system of a geest uplift in the Buchtenwatt, on which the oldest peat (basalt peat) has also been preserved. A total of 39 14C samples have so far been submitted to the LIAG isotope laboratory in Hanover for radiocarbon dating and should provide more detailed information on the timing of palaeolandscape development.
