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 depth, soil frost and
snow water content were measured at approximately biweekly intervals
on these plots from the first snowfall through the end of the
snowmelt. Snow and frost depth, and snow water content sampling
started in December 2010 and is ongoing. 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.

研究团队已在哈伯布鲁克实验林（Hubbard Brook Experimental Forest, HBEF）的多个测点开展了雪深、土壤冻深与雪水含量的测定工作。
2010年10月，作为一项关于雪深、土壤冻结与养分循环关系的研究（研究链接：http://www.ecostudies.org/people_sci_groffman_snow_summary.html）的一部分，研究团队沿海拔梯度布设了6个20×20米的集约样地与14个10×10米的扩展样地，其中8个样地朝向北坡，12个样地朝向南坡。
自首次降雪至融雪期结束，研究团队以约每两周一次的频率在上述样地开展雪深、土壤冻层厚度与雪水含量的测定工作。相关采样工作始于2010年12月，目前仍在持续进行中。
本数据集采集自哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）项目。哈伯布鲁克生态系统研究（HBES）是依托哈伯布鲁克实验林开展的协同研究项目，该实验林由美国农业部林务局（USDA Forest Service）北方研究站运营维护。
