Carbon and nitrogen lateral fluxes at Kytalyk research site (NE Russia) - year 2012

Measurements of dissolved organic carbon (DOC), nitrogen (DON) concentrations and water discharge at the outlet of the water catchment comprising the Kytalyk research station in North Eastern Russia (70.828845 N: 147.492320 E). Water samples were collected from June to August 2012 on a regular basis (every 2 days on average) and analyzed by Elemental Analyzer. Water discharge was measured by bucket method using a weir with a V notch to channel the stream flow. In case of diffuse overland flow, which occurred on June 15, the discharge was assessed on the basis of the measurements of the water flow speed and of the cross section of the water channels. Daily water discharge, DOC and DON fluxes are provided assuming the measured water flow rates as constant during each respective day. The area of the catchment was estimated in 0.99513 square km through the visual interpretation of a high resolution satellite image (GeoEye) combined with ground truth knowledge.

本数据集包含俄罗斯东北部Kytalyk研究站（北纬70.828845°，东经147.492320°）所在汇水区出水口处的溶解有机碳（Dissolved Organic Carbon, DOC）、溶解态有机氮（Dissolved Organic Nitrogen, DON）浓度及径流量实测数据。
研究于2012年6月至8月期间按固定采样频次（平均每2天1次）采集水样，并通过元素分析仪（Elemental Analyzer）完成实验室分析。径流量测定采用带V形缺口的测流堰导流，结合桶测法完成实测；针对2012年6月15日发生的坡面漫流事件，径流量通过水流流速与河道断面的实测数据进行估算。
本数据集提供逐日径流量、DOC与DON通量数据，计算时假设单日实测水流流速保持恒定。结合高分辨率卫星影像（GeoEye）的目视解译与地面实测验证资料，该汇水区的面积被估算为0.99513平方千米。
