Snow depth survey 2019 in North Slope, Alaska

This is the field measured snow depth data using an automatic snow depth probe (magnaprobe, Snow-Hydro LCC) in April 20-29, 2019 in North Slope, Alaska. The data are three different format: csv format (comma delimited text format), projected shape file (UTM zone 5), and unprojected shape file (geographical coordinate, WGS 84). The goal of this research project is to quantify the role of thermokarst lake drainage and drained thermokarst lake basin (DTLB) evolution in the arctic system. The joint research team (University of Alaska, Fairbanks and University of Wyoming) traveled over 19 days and approximately 1000 miles in Northern Alaska to make initial geophysical measurement on a range sites. Field work began in mid-April with several days based in Utqiagvik (Western Coastal Plain) in coordination with principle investigator Hinkel and his graduate student Ian Nichols. A group of six then departed for Teshekpuk Lake (Central Coastal Plain), followed by Inigok (Eastern Coastal Plain and Sand Sea), and Oumalik (Loess Belt and Sand Sea) before returning to Utqiagvik in early May. During the travel, manual snow survey was conducted using the mangaprobe to quantify the snowdrift around thermokarst lakes and other land features as complementary to the geophysical and remote sensed snowpack characterizations.本数据集为2019年4月20日至29日在阿拉斯加北坡地区，采用自动雪深探测仪（magnaprobe，Snow-Hydro LCC）采集的野外雪深实测数据。该数据集包含三种格式：逗号分隔文本格式（CSV）、投影坐标系形状文件（UTM 5区）以及非投影坐标系形状文件（地理坐标系WGS 84）。本研究项目旨在量化热喀斯特湖排水与已排水热喀斯特湖盆（drained thermokarst lake basin, DTLB）的演化在北极系统中的作用。由阿拉斯加大学费尔班克斯分校与怀俄明大学组成的联合研究团队，在阿拉斯加北部开展了为期19天、总行程约1000英里的野外工作，对多个研究点位开展初始地球物理测量。野外工作于4月中旬启动，先期在乌特恰维克（西部沿海平原）开展数日作业，与项目负责人辛克尔（Hinkel）及其研究生伊恩·尼科尔斯（Ian Nichols）协同完成。随后6人团队前往特谢普克湖（中部沿海平原），之后依次到访伊尼戈克（东部沿海平原与沙海区域）和乌马利克（黄土带与沙海区域），最终于5月初返回乌特恰维克。野外考察期间，研究团队使用magnaprobe开展人工雪深测量，以量化热喀斯特湖周边及其他地貌的积雪漂移情况，作为地球物理与遥感积雪特征表征的补充。
