A revised stratigraphical framework for the Quaternary deposits of the German North Sea sector: a geological‐geotechnical approach

Abstract: Using extensive data sets from three separate areas in the German North Sea sector, consisting of seismic grids, cores and in‐situ cone penetration tests (CPT), we have established a revised stratigraphical framework for the mid to late Quaternary deposits of the German North Sea sector. This framework consists of four regional unconformities and 15 other local unconformities derived from seismic profiles. Using these unconformities, along with lithological and geotechnical data, it was possible to define and … Show more

“…Previous explorations of submerged landscapes have used low-resolution 2D or 3D seismic reflection surveys designed to target deeper oil and gas reservoirs (Fitch et al, 2005;Gaffney et al, 2007Gaffney et al, , 2009 or combine oil and gas datasets with sparse high-resolution 2D seismic reflection data (Coughlan et al, 2018;Hepp et al, 2017Hepp et al, , 2019Prins and Andresen, 2019). Whilst this enables drainage networks to be identified, there is little information to constrain sedimentary and geomorphic processes and therefore the controls on landscape evolution.…”

“…The evolution of the terrestrial landscape of Dogger Bank over 10 kyr timescales, during a period of marked climate and far-field base-level change, has mainly focused on glacial (Cotterill et al, 2017b;Emery et al, 2019a;Phillips et al, 2018) and coastal stratigraphy (Emery et al, 2019a). Prins and Andresen (2019) established a transition from subglacial channel to terrestrial drainage in a study area 150 km northeast of Dogger Bank, but detail of the terrestrial landscape evolution at Dogger Bank during and after ice-sheet retreat has yet to be established.…”

“…The oldest sediment belongs to a large tunnel valley defined by Unit 1. Comparable tunnel valley in the area described by Hepp 15 , Lutz 28 and Coughlan 17 suggest that this unit is made up of glacio-fluvial sand deposited in the Pleistocene. This was followed by the infill Unit 2 defined by Reflectors R2_1 and R2_2.…”
