TERN Surveillance monitoring program: Soil vis-NIR spectral library with accompanying soil measurement data for 367 specimens

AusPlots is the core program delivered by TERN Surveillance. AusPlots is a plot-based surveillance monitoring program, undertaking baseline assessments of ecosystems across the country. The aim of AusPlots is to establish and maintain a national network of plots that enables consistent ecological assessment and ongoing monitoring. The AusPlots network collects a range of field data for integration with other existing data sources and current knowledge. More information about TERN Surveillance can be found at their website - https://www.tern.org.au/tern-observatory/tern-ecosystem-surveillance/\n\nAs of 2020 there are about 690 active AusPlot sites distributed across Australia.\n\nDuring 2018 to 2019, most of the soil specimens collected at the AusPlots sites were scanned with an ASD portable vis-NIR spectrometer (PANalytical Inc., Boulder, CO, USA). As there is a specific field data collection protocol carried out at each site i.e., numerous spatial distributed samples collected in a grid-design of specified dimensions, this meant a substantial number of specimens to scan. In total there were 19,380 vis-nir spectra collected. The scanning was done at CSIRO Waite Campus with a CSIRO owned vis-NIR spectrometer.\n\nAccompanying the soil vis-NIR library is a dataset of analytical soil measurements for 367 soil specimens selected the Ausplots soil specimen archive. \n\n\n\n\nLineage: The condition of the soil for vis-NIR data collection was: Air-dried and ground to

AusPlots是由TERN监测项目（TERN Surveillance）推出的核心项目。AusPlots是一项基于样地的监测项目，负责对澳大利亚全国范围内的生态系统开展基线评估。其目标是建立并维护一套国家级样地网络，以实现标准化的生态评估与持续监测。该网络会采集多类野外数据，用于与其他现有数据源及现有研究成果进行整合。有关TERN监测项目（TERN Surveillance）的更多信息可访问其官方网站：https://www.tern.org.au/tern-observatory/tern-ecosystem-surveillance/

截至2020年，澳大利亚境内共设有约690个活跃的AusPlots样地站点。

2018至2019年间，研究人员对AusPlots站点采集的大部分土壤标本使用ASD便携式可见-近红外光谱仪（vis-NIR spectrometer，PANalytical Inc.，美国科罗拉多州博尔德市）进行了扫描。由于每个站点均遵循统一的野外数据采集规范，即按照指定尺寸的网格设计采集大量空间分布的样本，因此需要扫描的土壤标本数量十分庞大。本次共采集到19380条可见-近红外光谱数据。扫描工作在澳大利亚联邦科学与工业研究组织（CSIRO）韦特校区完成，使用的是CSIRO自有可见-近红外光谱仪。

该土壤可见-近红外光谱库配套包含一套分析土壤测量数据集，涵盖从AusPlots土壤标本库中选取的367份土壤标本的相关检测数据。
