Snow depth, soil frost depth and snow water content along an elevation gradient at the Hubbard Brook Experimental Forest.

Snow depth, soil frost depth and snow water content have been measured at several locations at the Hubbard Brook Experimental Forest (HBEF). In October 2010, as part of a study of the relationships between snow depth, soil freezing and nutrient cycling (http://www.ecostudies.org/people_sci_groffman_snow_summary.html), we established 6 20 x 20-m plots (intensive plots) and 14 10 x 10-m plots (extensive plots) following an elevation gradient, with eight of the plots facing north and twelve facing south. Snow and frost depth, and snow water equivalent sampling started in December 2010. Measurements on the extensive plots ended at the conclusion of snow coverage in spring, 2012. Measurements at the 6 intensive plots are ongoing and measurement frequency was increased from approximately bimonthly to approximately weekly beginning in the 2019-2020 snow cover season. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

本数据集针对哈伯德布鲁克实验林（Hubbard Brook Experimental Forest, HBEF）内多个点位的雪深、土壤冻深及雪水含量开展观测。2010年10月，为探究雪深、土壤冻结与养分循环之间的关联（研究参考链接：http://www.ecostudies.org/people_sci_groffman_snow_summary.html），研究团队沿海拔梯度布设了6块20×20米的密集样地与14块10×10米的扩展样地，其中8块朝向北坡、12块朝向南坡。2010年12月正式启动雪深、冻深及雪水当量的采样工作。扩展样地的观测工作于2012年春季积雪消融后终止。6块密集样地的观测仍在持续，且自2019-2020年积雪季起，观测频率从约每两月一次提升至约每周一次。本数据集作为哈伯德布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）的组成部分收集完成，该研究是在哈伯德布鲁克实验林内开展的协作项目，而该实验林由美国农业部林务局北方研究站（USDA Forest Service, Northern Research Station）运营维护。
