Ramped Temperature CO2 Evolution for Permafrost and Kolyma River Dissolved Organic Carbon

This dataset is the CO2 (ppm) produced as a function of increasing temperature combustion of dissolved organic carbon at a constant 5°C per minute ramped rate with a constant flow-through of oxygen. Dissolved organic carbon samples were gathered from a permafrost thaw stream and the Kolyma River in northeastern Siberia and subjected to microbial incubation degradation before investigation by ramped pyrolysis oxidation. Data is used to create a thermogram followed by inverse modeling to garner chemical composition based on thermostability. Samples were analyzed to determine the contribution of permafrost dissolved organic carbon to the Kolyma River.本数据集记录了在恒定每分钟5℃的升温速率、持续通氧的条件下，溶解性有机碳（dissolved organic carbon）燃烧过程中产生的二氧化碳（CO₂，百万分比浓度ppm）随温度升高的变化数据。 研究人员从西伯利亚东北部的永久冻土（permafrost）解冻溪流与科雷马河（Kolyma River）采集了溶解性有机碳样品，所有样品在通过升温热解氧化法（ramped pyrolysis oxidation）开展分析前，均先经过微生物培养降解处理。 该数据集可用于绘制热解热谱图，随后通过逆建模方法，基于热稳定性推导得到样品的化学组成。 本次分析旨在明确永久冻土溶解性有机碳对科雷马河的贡献占比。
