冰杂岩是东西伯利亚北部特有的富冰建造，是北极碳库的重要组成部分。最近，这些晚第四纪沉积成为许多调查的目标，通常依靠露头和钻孔数据。这些研究中的许多都可以受益于地下的3D结构模型，以扩大他们的观测范围，或限制对清单的估计，如当地的碳储量。我们已经解决了3D探地雷达(GPR)的结构成像问题，在多年冻土研究中，GPR主要用于2D剖面图。我们在位于新西伯利亚群岛冰上的一个现场使用了3D动态探地雷达测量策略。在应用三维探地雷达处理序列后，我们能够在20米以下的深度追踪到两个层位。考虑到现有的钻孔和露头资料，我们将这两个特征解释为主要岩性单元和地层的界面。
ABSTRACTIce complex deposits are characteristic, ice-rich formations in northern East Siberia and represent an important part in the arctic carbon pool. Recently, these late Quaternary deposits are the objective of numerous investigations typically relying on outcrop and borehole data. Many of these studies can benefit from a 3D structural model of the subsurface for upscaling their observations or for constraining estimations of inventories, such as the local carbon stock. We have addressed this problem of structural imaging by 3D ground-penetrating radar (GPR), which, in permafrost studies, has been primarily used for 2D profiling. We have used a 3D kinematic GPR surveying strategy at a field site located in the New Siberian Archipelago on top of an ice complex. After applying a 3D GPR processing sequence, we were able to trace two horizons at depths below 20 m. Taking available borehole and outcrop data into account, we have interpreted these two features as interfaces of major lithologic units and der...
