Magnaprobe snow and melt pond depth measurements from the 2019-2020 MOSAiC expedition@en

At MOSAiC, we collected snow depths by Magnaprobe - an automated snow depth probe, throughout the seasons, most often alongside electromagnetic measurements for deriving total thickness. Most of the data were collected routinely along established transect lines and loops to create timeseries. Some data were collected opportunistically e.g., during 'events'. In addition, several repeated ridge transects were established. During the melt season (June – September 2020), the Magnaprobe was used to measure snow depth, surface scatter layer depth and melt pond depth. This repository includes data obtained by Magnaprobe, sea ice thickness derived by subtracting snow depth from co-located total thickness measurements, a descriptive document including maps (Magnaprobe Repository Description), and a table of with other transect-mode measurements at MOSAiC (Action Log Table): remote sensing instruments, snow structure measurements etc.

在MOSAiC科考计划中，我们使用Magnaprobe——一款自动化雪深探测仪——开展了全季节雪深数据采集工作，多数情况下同步开展电磁测量以推求总厚度。绝大多数数据沿预设的测线与环线进行常规采集，以构建时间序列。部分数据为应急采集，例如在‘特殊事件’期间。此外，还布设了多条重复的脊状测线。在2020年6月至9月的融化季期间，Magnaprobe被用于测量雪深、表面散射层深度以及融池深度。本数据集仓库包含通过Magnaprobe获取的数据、通过同位置同步总厚度测量值减去雪深推导得到的海冰厚度数据、一份附带地图的说明文档（Magnaprobe Repository Description），以及一份记录MOSAiC科考中其他测线模式测量数据的表格（Action Log Table）：其中涵盖遥感仪器、雪层结构测量等相关内容。
