Carbon and nutrient data for rainfall fractions in the Peruvian Amazon

Aquatic carbon (dissolved inorganic carbon (DIC), dissolved organic carbon (DOC) and particulate organic carbon and the carbon isotopic composition of DIC) and nutrients (calcium, magnesium, potassium, sodium, total soluble phosphorus and silica) in rainfall fractions (rainwater, throughfall, stemflow and overland flow) were sampled in the Western Amazonian basin. The samples were collected towards the end of a wet season April - May 2012. Rainfall and throughfall samples were collected in plastic buckets. Stemflow samples were collected using stemflow collection systems. Overland samples were collected using a a plastic pipe cut lengthways directing flow into a plastic bucket. Established standard methods were used to analyse the DIC, DOC and nutrients. These methods are outlined in the lineage. The samples were taken to understand the nutrient and carbon delivery in rainwater as well as leaching from tree canopies, stems and from the soil surface. The data collection was carried out as part of the Natural Environment Research Council (NERC) funded Amazonica project (NE/F005482/1).

在西亚马逊盆地，对降水分（雨水、穿透雨、树干流和地表径流）中的水生碳（溶解无机碳（DIC）、溶解有机碳（DOC）及颗粒有机碳）和养分（钙、镁、钾、钠、总溶解性磷和硅）进行了采样。样本收集于2012年4月至5月雨季尾声。雨水和穿透雨样本收集于塑料桶中。树干流样本通过树干流收集系统收集。地表径流样本通过纵向切割的塑料管引导水流至塑料桶中收集。DIC、DOC和养分的分析采用了既定的标准方法，具体方法详见谱系。这些样本的采集旨在了解雨水中的养分和碳输送，以及从树冠、树干和地表土壤中的淋溶情况。数据收集是作为自然环境研究委员会（NERC）资助的Amazonica项目（NE/F005482/1）的一部分进行的。关于此数据集的详细信息可在https://doi.org/10.5285/59bdb8f6-fb1f-418f-a53c-394f6c68a334中找到。
