Carbon and nutrient data for streams in the Peruvian Amazon

Data from two small streams, two rivers and rainfall fractions in the Western Amazonian basin at Tambopata National Reserve in Madre de Dios region, Peru. Data presented are nutrients (calcium, magnesium, potassium, sodium, total soluble phosphorus and silica) and fluvial carbon - dissolved inorganic carbon (DIC) and its isotopic composition δ13C-DIC, dissolved organic carbon (DOC) and particulate organic carbon (POC). Samples were collected during the period from February 2011 to May 2012 targeting both wet and dry seasons. Samples for DIC samples were collected using pre-acidified evacuated Exetainers. Established standard methods were used to take samples for DOC and nutrients. Established standard methods were used to analyse samples for DIC, DOC and nutrients These methods are outlined in the lineage. The samples were taken to understand the hydrological controls on the carbon concentrations and fluxes during different flow conditions. The data collection was carried out as part of the Natural Environment Research Council funded Amazonica project.

本数据集收录了秘鲁马德雷德迪奥斯地区坦博帕塔国家保护区西部亚马逊盆地中两条小溪、两条河流及降水的碳组分数据。所呈现的数据包括营养素（钙、镁、钾、钠、全溶性磷和二氧化硅）以及河流碳组分——溶解无机碳（DIC）及其同位素组成δ13C-DIC、溶解有机碳（DOC）和颗粒有机碳（POC）。采样工作于2011年2月至2012年5月期间进行，旨在覆盖湿季和干季。DIC样品的采集采用预先酸化的排空Exetainer。DOC和营养素的采样均采用既定标准方法。对DIC、DOC和营养素的样品分析同样遵循了既定标准方法，具体分析流程见溯源信息。采样目的在于探究不同流量条件下碳浓度及通量的水文控制因素。数据收集工作是自然环境研究委员会资助的亚马逊ica项目的组成部分。关于本数据集的详细信息可查阅https://doi.org/10.5285/ee1b9eb7-6fbd-4dd5-8f8f-e07d32c057e4。
