Table 1 : AMS-14C data used for the reconstruction of the Wismar Bay shoreline displacement curve

The Baltic coast of Mecklenburg-Vorpommern is located in the transition Zone between the region of Fennoscandian Uplift and the Central European Depression. In relation to the eustatic sea-level rise, the northeast coast shows a slower inundation, while for the southwestern area a faster transgression is indicated, which can be attributed to crustal movements. To determine the spatial and temporal differences since the onset of the Littorina Transgression, three relative sea-level curves have been established along a transect parallel to the gradient of upliftlsubsidence. The Wismar Bay area is one endpoint of the transect demonstrating today 10 Abb., 2 Tab. a relative sea-level rise of 1.4 mm/a. To determine the relative sea-level curve for the Wismar Bay, two sites were investigated on Rustwerder Spit (Poel) and Redentin. They provided reliable depth-age data, while the stratigraphy was additionally supported by lithological/geochemical, pollen, diatom and macrofossil data. Additional evidence was provided by archaeological submarine surveys and excavations. Comparing the new relative sea-level curve with a curve from the Vorpommern coast, it can be shown that for the period from 4000 cal BC until present, the differences between the two curves are caused by a constant neotectonic movement, while for the older periods an increasing isostatic component must be taken into account.

梅克伦堡-前波美拉尼亚（Mecklenburg-Vorpommern）的波罗的海沿岸地处芬诺斯坎德兰隆起带（Fennoscandian Uplift）与中欧沉降区（Central European Depression）之间的过渡带。相较于全球海平面上升（eustatic sea-level rise），该区域东北海岸的海水淹没速率较慢，而西南海域则表现出更快的海侵现象，这一差异可归因于地壳运动。为厘清自里托里纳海侵（Littorina Transgression）发生以来的时空差异，研究人员沿一条平行于隆起-沉降梯度的地质剖面，构建了三条相对海平面曲线。维斯马湾（Wismar Bay）区域为该地质剖面的端点之一，当前观测到其相对海平面上升速率为1.4 mm/a，本研究附10幅插图、2张表格。为构建维斯马湾的相对海平面曲线，研究人员对波埃尔岛上的鲁斯特韦德沙洲（Rustwerder Spit）以及雷登廷（Redentin）两处遗址开展了调查。两处遗址提供了可靠的深度-年代数据，地层学分析则辅以岩性、地球化学、孢粉、硅藻以及大化石相关数据作为支撑。水下考古调查与发掘工作提供了额外的佐证证据。将本次构建的相对海平面曲线与前波美拉尼亚海岸的已有曲线进行对比后可知，在校准公元前4000年至今的时间段内，两条曲线的差异源于持续的新构造运动；而在更早的时期，则需考虑不断增强的地壳均衡分量的影响。
