We present for the first time a three-dimensional (3D) reconstruction of the palaeoenvironment of 63 ha covering subarea of the former lake during the Mesolithic. The archaeological aims focus on detecting the location of former islands hosting hunter-gatherers settlements and on reconstructing the ancient landscape development for understanding prehistoric land use. Clusters of Mesolithic camps have been found located on small sand hills that formed islands in the prehistoric lake. For this environment, we present depth maps of the three most important sedimentary facies interfaces of ancient Lake Duvensee. Stratigraphic information from the corings enabled us to create a 3D model of the spatio-temporal development of the Duvensee bog. The locations of the islands and their estimated dive-up times agree with the spatio-temporal pattern of the previous archaeological finds. The model shows where hunter-gatherers could settle and move from one island to another following the shorelines of the overgrowing lake. en database 550 his Host institution aut Author Corradini, Erica 0000-0003-4266-8589 Corradini Erica Wilken, Dennis aut Author 0000-0002-5128-351X Wilken Dennis Panning, Diana aut Author 0000-0002-3167-0360 Panning Diana Pickartz, Natalie aut Author 0000-0002-3290-7032 Pickartz Natalie 10.57892/100-82 Rusch, Katharina aut Author Rusch Katharina Mecking, Rebekka aut Author 0000-0002-2651-2077 Mecking Rebekka Erkul, Ercan aut Author 0000-0003-3396-807X Erkul Ercan Rabbel, Wolfgang aut Author 0000-0003-4720-6906 Rabbel Wolfgang Zanon, Marco ctb Contributor Zanon Marco Gross, Daniel ctb Contributor Gross Daniel Lübke, Harald ctb Contributor Lübke Harald Dörfler, Walter ctb Contributor Dörfler Walter Feeser, Ingo ctb Contributor Feeser Ingo 2016 2018 2022 290391021 Archäologische Prospektion Ground Penetrating Radar 53.696541, 10.546459 Duvensee region A GSSI GPR unit with a 200 MHz center frequency antenna was used to investigate the Duvensee area. A rectangular grid of GPR profiles was established to investigate the palaeolandscape with 30-m spacing in the northern part of the area. In the southern sector, the profile spacing is ca. 100 m in NS direction and 30 m in WE direction (Figure 1c). For deriving a 3D stratigraphic subsurface model, it was necessary to recognize and pick in every radargram the reflections associated with the interfaces between the main sedimentary units identified in the drill cores. We recognized three main reflectors: Interface1 represents the transition between coarse organic sediments (peat and coarse detritus gyttja) and fine-grained organic sediments (fine detritus gyttja, calcareous gyttja), Interface2 represents the transition to the underlying clayish-loamy sediments, and Interface3 marks the top of the basal sand deposits at the lake bottom. From Interface3, we identified the location and extent of five former islands with Mesolithic camps. The picked reflectors were finally interpolated and a map showing the depth of each interface was created. For converting reflection time to depth, we used velocity-depth functions determined from common-midpoint (CMP) measurements that had been carried out separately. In this way, a specific wave velocity was attributed to each layer. The resulting 3D model of the investigated area was finally created and visualized using the Surfer software. The 3D stratigraphic model provides growth and shrinking rates of the island and lake areas in the Mesolithic, and volumes of organic and non-organic deposited lake sediments. Besides, it provides a basis for a sustainable groundwater management needed for heritage preservation. fdr_mods_00000082 https://opendata.uni-kiel.de/receive/fdr_mods_00000082
