High resolution incubation measurements

Soil samples were taken in the bog site of the Siikaneva peat complex and adjacent shrub-belt and forest site in Ruovesi, Finland. Samples were characterized by measuring water content, bulk density, C and N content and further parameters. Samples were collected on 2020-10-22 and 2020-10-23. A subset of samples was taken for a 53 day incubation experiment at 20°C in June 2021. The aim was to measure microbial CO2 production rates of soil samples with varying soil characteristics and water contents to test and establish a new method for incubation measurements with high temporal resolution using a LI-7810. For further information on the method see https://ghg-in-permafrost.awi.de/ .Incubation measurement files contain single incubation measurements of about 10 to 20 minutes length with CO2 concentration measurements with a resolution of 1Hz conducted with a LICOR Trace Gas Analyzer (LI-7810). The data format is described here (section 3, page 5): https://www.licor.com/documents/zsce2z88fgkfpbiguqi0k3g537jllsl7 .本研究于芬兰吕韦斯（Ruovesi）地区的西卡涅瓦（Siikaneva）泥炭复合体沼泽样地及其邻近的灌丛带与森林样地采集土壤样品。通过测定含水率、容重、碳（C）、氮（N）含量及其他相关参数对样品进行理化表征。样品采集时间为2020年10月22日与23日。2021年6月选取部分样品开展为期53天的20℃恒温培养实验。本实验旨在测定不同土壤理化特性与含水率的土壤样品的微生物CO₂产生速率，以检验并建立一种依托LI-7810分析仪实现高时间分辨率培养测定的新方法。有关该方法的详细信息可参考：https://ghg-in-permafrost.awi.de/。培养测定文件包含单次时长约10至20分钟的培养实验数据，其中CO₂浓度测定采用LICOR痕量气体分析仪（LI-7810）完成，采样分辨率为1Hz。该数据集的数据格式详见以下链接（第3章节，第5页）：https://www.licor.com/documents/zsce2z88fgkfpbiguqi0k3g537jllsl7。
