KML files of the identified dune units with their interpreative classifications, and types of lakes basins

In this study, the morphology of the dunes located in the coastal stretch between Inharrime and Inhambane (Mozambique) is analysed using remote sensing-based datasets, including open-source satellite imagery and digital terrain models, to explore the link between dune evolution and lake genesis. This analysis allowed identification of two types of dunes based on their morphology. The first being shore-parallel ridges, interpreted as ancient coastal barriers, and the second being mostly parabolic dunes and trailing arms perpendicular to the present-day coastline, interpreted as transgressive dunes. By comparing the position of these coastal barriers and the global sea-level curve, an age was tentatively assigned to each barrier. The barriers are suggested to have been formed during marine interstadial events, namely between MIS13 and MIS 5, when sea level was high. In contrast, the transgressive dunes seem to have formed later, although determining their precise origins remains a difficult task. Considering the types of dunes, two types of lake basins were identified: back-barrier depressions and deflation basins.

本研究以莫桑比克因哈里梅（Inharrime）与伊尼扬巴内（Inhambane）之间沿岸地带的沙丘为研究对象，采用开源卫星影像、数字地形模型（digital terrain models）等遥感数据集开展形态分析，旨在探究沙丘演化与湖泊成因之间的关联。本次分析基于形态特征识别出两类沙丘：其一为与岸线平行的脊状构造，被解读为古海岸屏障；其二以抛物线沙丘（parabolic dunes）及垂直于现代岸线的尾臂为典型特征，被判定为海侵沙丘（transgressive dunes）。通过将上述海岸屏障的分布位置与全球海平面曲线进行比对，研究人员为每一处海岸屏障初步推定了形成年代。据推测，该类屏障形成于海洋间冰段事件期间，即MIS13至MIS5时期，彼时全球海平面处于高位。与之相对，海侵沙丘的形成时间相对较晚，但其确切成因目前仍难以明确。结合沙丘类型特征，研究人员还识别出两类湖盆：屏障后洼地（back-barrier depressions）与风蚀洼地（deflation basins）。
