Snow Melt Transect ARCSS grid Barrow, Alaska 2011

A 200 meter snow melt transect was chosen within the Arctic System Science (ARCSS) grid in Barrow, Alaska. ARCSS grid coordinates are labeled A through K and 1 through 11 for each N-S and E-W row of markers respectively. Transect begins 2 meters west of ARCSS grid point D09 and extends south ending 2 meters west of ARCSS grid point F09. Depth measurements were taken at every 2 meters along the transect on the east side of the transect to avoid any disturbances. The Systems Ecology Lab at the University of Texas El Paso (SEL) Circumpolar Active Layer Monitoring (CALM) depth probe was used for the measurements. Location of the snow melt transect was chosen using ArcGis tools.

本数据集选取了位于阿拉斯加巴罗地区北极系统科学（Arctic System Science, ARCSS）网格内的一条200米融雪样带。ARCSS网格坐标分别以A至K、1至11标记南北向与东西向的标记行。该样带始于ARCSS网格点D09西侧2米处，向南延伸，终止于ARCSS网格点F09西侧2米处。为避免干扰，本次测量在样带东侧每隔2米开展一次深度采样。测量工作采用德克萨斯大学埃尔帕索分校系统生态学实验室（Systems Ecology Lab, SEL）的环极活动层监测（Circumpolar Active Layer Monitoring, CALM）深度探针完成。融雪样带的点位选取借助ArcGIS工具实现。
