Abstract. We present the geophysical data set acquired in summer 2022 close to Ny-Ålesund (western Svalbard, Brøggerhalvøya Peninsula, Norway) as part of the project ICEtoFLUX. The aim of the investigation is to characterize the role of groundwater flow through the active layer as well as through and/or below the permafrost. The data set is composed of electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) surveys, which are well-known geophysical techniques for the characterization of glacial and hydrological processes and features. Overall, 18 ERT profiles and 10 GPR lines were acquired, for a total surveyed length of 9.3 km. The data have been organized in a consistent repository that includes both raw and processed (filtered) data. Some representative examples of 2D models of the subsurface are provided, that is, 2D sections of electrical resistivity (from ERT) and 2D radargrams (from GPR). The resistivity models revealed deep resistive structures, probably related to the heterogeneous permafrost, which are often interrupted by electrically conductive regions that may relate to aquifers and/or faults. The interpretation of these data can support the identification of the active layer, the occurrence of spatial variation in soil conditions at depth, and the presence of groundwater flow through the permafrost. To a large extent, the data set can provide new insight into the hydrological dynamics and polar and climate change studies of the Ny-Ålesund area. The data set is of major relevance because there are few geophysical data published about the Ny-Ålesund area. Moreover, these geophysical data can foster multidisciplinary scientific collaborations in the fields of hydrology, glaciology, climate, geology, and geomorphology, etc. The geophysical data are provided in a free repository and can be accessed at https://doi.org/10.5281/zenodo.10260056 (Pace et al., 2023).

斯瓦尔巴群岛尼奥勒松附近 2022 年夏季电阻率断层扫描和探地雷达数据的新存储库


摘要。作为 ICEtoFLUX 项目的一部分，我们展示了 2022 年夏季在 Ny-Ålesund（斯瓦尔巴群岛西部，挪威 Brøggerhalvøya 半岛）附近采集的地球物理数据集。研究的目的是表征地下水流穿过活动层以及穿过永久冻土层和/或永久冻土层下方的作用。该数据集由电阻率层析成像（ERT）和探地雷达（GPR）勘测组成，它们是用于表征冰川和水文过程和特征的众所周知的地球物理技术。总体而言，获得了 18 条 ERT 剖面和 10 条 GPR 测线，总测量长度为 9.3 公里。数据已组织在一个一致的存储库中，其中包括原始数据和经过处理（过滤）的数据。提供了地下二维模型的一些代表性示例，即电阻率的二维剖面（来自 ERT）和二维雷达图（来自 GPR）。电阻率模型揭示了深层电阻结构，可能与异质永久冻土有关，这些结构经常被可能与含水层和/或断层有关的导电区域中断。对这些数据的解释可以支持活动层的识别、深度土壤条件的空间变化的发生以及穿过永久冻土的地下水流的存在。在很大程度上，该数据集可以为新奥勒松地区的水文动力学以及极地和气候变化研究提供新的见解。该数据集具有重要意义，因为有关新奥勒松地区的地球物理数据很少发布。此外，这些地球物理数据可以促进水文学、冰川学、气候学、地质学和地貌学等领域的多学科科学合作。 地球物理数据在免费存储库中提供，可以通过 https://doi.org/10.5281/zenodo.10260056 访问（Pace 等人，2023）。
