Carbon flux measurements from chambers collected between July to October 2022 at Old Woman Creek, Huron, Ohio.

This dataset contains carbon dioxide and methane flux measurements collected via chamber sampling at Old Woman Creek National Estuarine Research Reserve in Huron, OH. These data were generated to understand temporal and vegetation patterns associated with wetland carbon cycling. Specifically, this dataset intends to answer how carbon dioxide and methane fluxes change monthly and hourly across sites with vegetation and without vegetation. Data includes chamber measurements that were measured in both sites with vegetation and without vegetation and that were collected hourly, for 12 hours, and monthly, for four months. The file soilrespiration_data.csv contains these data, and the metadata file (soilrespiration_chammetadata.csv) and location metadata file (soilrespiration_locationmetadata.csv) have information on locations where the chambers were placed and sampled in the wetland. Data processing was done on raw methane fluxes (Flux_CH4) to remove the influence of ebullition (Flux_CH4_ebullition) to get a diffusive flux (Flux_CH4_diffusive).本数据集包含采自美国俄亥俄州休伦市老妇人溪国家河口研究保护区、采用箱式采样法获取的二氧化碳与甲烷通量观测数据。本数据集的构建目的为解析湿地碳循环相关的时间动态与植被关联格局。具体而言，本数据集旨在阐明有植被与无植被样地内，二氧化碳与甲烷通量的月际及小时尺度变化规律。数据集涵盖有植被与无植被两类样地的箱式采样数据，采样按小时开展（单次连续采样时长12小时），且按月进行，持续时长共计4个月。数据文件soilrespiration_data.csv包含上述观测结果；配套的元数据文件soilrespiration_chammetadata.csv与位置元数据文件soilrespiration_locationmetadata.csv记录了湿地内采样箱的布设点位信息。研究人员对原始甲烷通量（Flux_CH4）进行了预处理，剔除冒泡排放过程（Flux_CH4_ebullition）的干扰，最终得到扩散型甲烷通量（Flux_CH4_diffusive）。
