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/ As of 2020 there are about 690 active AusPlot sites distributed across Australia. During 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. Accompanying the soil vis-NIR library is a dataset of analytical soil measurements for 367 soil specimens selected the Ausplots soil specimen archive.

AusPlots是由TERN Surveillance主导实施的核心项目，是一项基于样地的生态监测计划，旨在开展全国范围内的生态系统基线评估。该项目的目标是建立并维护全国性样地网络，为一致性生态评估与持续监测提供支持。AusPlots网络收集各类实地数据，以与现有数据源及当前知识体系整合。有关TERN Surveillance的更多信息可访问其官网：https://www.tern.org.au/tern-observatory/tern-ecosystem-surveillance/。截至2020年，澳大利亚境内分布有约690个活跃的AusPlots样地站点。2018至2019年间，AusPlots样地采集的大部分土壤样本通过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）进行扫描。由于每个站点均遵循特定的实地数据采集规程——即按指定尺寸网格设计采集大量空间分布样本，因此需扫描的样本数量庞大。本次扫描共获取19380条可见-近红外光谱数据，扫描工作在CSIRO Waite校区完成，使用的是CSIRO自有可见-近红外光谱仪。随土壤可见-近红外光谱库一同提供的，还有从AusPlots土壤样本档案中选取的367份土壤样本的分析测量数据集。
