Seismic data from the foreland of the glacier Midtdalsbreen (Norway) in spring, 2018-2019.

This dataset contains raw and stacked seismic survey files collected over three sites at the foreland of the glacier Midtdalsbreen in southern Norway. Information on data collection is provided is corresponding observer logs files (…_obslogs.xlsx). The data was collected in the spring, when the ground was snow covered.Once processed, this data can provide information on the elastic properties of the substrates beneath the survey lines.Seismic files were collected using 48 vertical component geophones and a sledgehammer source with maximum geophone spread lengths of 47 m and 70.5 m for the Terminal Moraine Site and Hummocky and Lateral Moraine sites, respectively. The subsurface at the Hummocky Site violates the assumptions for planar and plus-minus seismic refraction interpretation so this data should not be used for these purposes.See Watts et al. (2022) for detail on data collection.

本数据集收录了挪威南部米达尔斯布雷恩（Midtdalsbreen）冰川冰前区三个测点的原始与叠加地震勘探文件。数据采集的相关说明已配套收录于对应的观测日志文件（…_obslogs.xlsx）中。本次数据采集工作开展于春季，彼时地面完全被积雪覆盖。经处理后，该数据集可用于反演测线下方基底的弹性属性参数。本次地震数据采集采用48道垂直分量检波器与大锤震源，其中终碛垄测点的检波器最大排列长度为47米，冰碛丘陵测点与侧碛垄测点的检波器最大排列长度均为70.5米。需注意，冰碛丘陵测点的地下介质不符合平面折射与正负法地震折射解释的假设前提，因此该数据不可用于此类解释场景。有关数据采集的详细细节，请参阅Watts等人（2022）的研究文献。
