Krui Catchment Soil Organic Carbon Data

The two files contain soil organic carbon (% w/w) data for the Krui River catchment in NSW, Australia. It consists of field data (“Krui_20cm_SOC.csv”) and modelled data (“BIOS2_Krui_SOC_1908-2015.csv”) used to study the impact of drought on soil organic carbon. Soil organic carbon concentrations were determined using soil cores collected to 20 cm depth in 2006, 2015 and 2018 to study the impacts of recent droughts, while the BIOS2 model outputs (Haverd et al., 2013) from 1911-2015 were used to study the impacts of historical droughts. The area of study is the Krui River catchment (585 km2) in NSW, Australia. The catchment extends from 31° 49’ to 32° 13’S and from 150° 02’ to 150° 21’E. “BIOS2_Krui_SOC_1908-2015.csv” presents soil organic carbon data at annual timesteps from 1911-2015 for the catchment. “Krui_20cm_SOC.csv” presents soil organic carbon data collected across the catchment in 2006, 2014 and 2018.

本数据集包含两个文件，涵盖澳大利亚新南威尔士州（New South Wales, NSW）克鲁伊河（Krui River）流域的土壤有机碳（soil organic carbon）质量百分比（% w/w）数据，用于探究干旱对土壤有机碳的影响，其中包含野外实测数据（"Krui_20cm_SOC.csv"）与模拟数据（"BIOS2_Krui_SOC_1908-2015.csv"）。
2006、2015及2018年采集的深度达20 cm的土芯样本被用于测定土壤有机碳浓度，以此研究近期干旱的影响；而1911—2015年的BIOS2模型（Haverd等，2013）输出结果，则被用于分析历史干旱的影响。
本研究区域为澳大利亚新南威尔士州克鲁伊河流域，流域面积585 km²，地理范围介于南纬31°49′至32°13′、东经150°02′至150°21′之间。
"BIOS2_Krui_SOC_1908-2015.csv"收录了该流域1911—2015年的年尺度土壤有机碳数据；"Krui_20cm_SOC.csv"则包含2006、2014及2018年在该流域采集的土壤有机碳实测数据。
