Cone Pond Watershed: Soil Profiles (Pedons), 1988-2023

Cone Pond Watershed: Soil Profiles (Pedons), 1988-2023 This dataset documents pedons (soil profiles) sampled at Cone Pond Watershed, Thornton, New Hampshire. Since the early 1980’s, Cone Pond, on the Pemigewasset District of the White Mountain National Forest, has been an active research satellite site to the nearby Hubbard Brook Experimental Forest. In 1988, intensive monitoring began as part of a comprehensive watershed scale ecosystem study. A weir was built on the main inlet stream, just above its mouth at Cone Pond, to monitor streamflow. Two rain gages were installed to monitor atmospheric deposition and multiple studies of major ecosystem components were initiated. Soil profiles documented in this dataset were sampled between 1988 and 2003. All descriptive profile and horizon data as well as chemical analyses of samples of genetic horizons are included in this dataset. Samples from 123 of these horizons have been accessioned into the Hubbard Brook physical sample archive; the archived mass of each is included in the horizon table. In addition to these pedons sampled in detail, a number of reconnaissance observations, made at a lower level of detail, and without sampling, were made in 2023 in order to validate a hydropedologic soil model created at Hubbard Brook. These data are included in a separate table. 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.圆锥池塘流域：土壤剖面（Pedons），1988-2023 本数据集收录了新罕布什尔州桑顿市圆锥池塘流域内采集的土壤剖面相关数据。自20世纪80年代初以来，位于白山国家森林佩米奇瓦塞特区的圆锥池塘，便作为邻近哈伯德布鲁克实验林的活跃研究卫星站点开展科研工作。1988年，作为流域尺度综合生态系统研究的一部分，该区域启动高强度监测工作：在圆锥池塘入口上游的主进水溪修建测流堰以监测径流量，安装两台雨量计以监测大气沉降，并启动多项针对主要生态系统组分的研究。 本数据集收录的土壤剖面采集于1988年至2003年间，包含所有剖面及发生层的描述性数据，以及遗传发生层样品的化学分析结果。其中123个发生层的样品已被收纳至哈伯德布鲁克实物样品库，各存档样品的质量均已录入发生层数据表中。 除上述详细采样的土壤剖面外，2023年还开展了若干概查观测：此类观测以较低精度开展且未进行采样，用于验证哈伯德布鲁克研发的水文土壤学模型，相关数据已单独录入一张数据表中。 本数据集数据隶属于哈伯德布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）项目。该项目由哈伯德布鲁克实验林牵头开展协作研究，其运营维护方为美国农业部林务局北部研究站。
