Sestonic particulate carbon, nitrogen, and phosphorus data from the Kuparuk River, near Toolik Field Station, Alaska, summers 1994-2010

Samples were collected to be analyzed for sestonic particulate carbon, nitrogen, and phosphorus. Samples from designated stations from the Kuparuk River were collected for particulates during each summer from 1994 to current time. Phosphorus addition has occurred since 1983; station sites are relative distance from the original 1983 phosphorus dripper. Stations include sites in a reference, recovery, and fertilized reach. Reaches were defined based on the location of phosphorous addition (see methods). Phosphoric acid is added to the stream to increase the soluble reactive phosphorus by 0.32 uM. Three sampling dates occurred each summer; once in June prior to the start of fertilization and once each in July and August.

本数据集采集样本用于分析悬浮颗粒碳（sestonic particulate carbon）、氮及磷的含量。1994年至今的每个夏季，研究人员均从库帕鲁克河（Kuparuk River）的指定站位采集悬浮颗粒物样本。自1983年起，该河段已开展磷添加实验；各站位以其与1983年初始磷滴加装置的相对距离作为标识依据。站位涵盖参照样带、恢复样带与施肥样带三类区域，样带划分依据磷添加位置确定（详见实验方法）。实验通过向河道投加磷酸，将可溶性反应磷（soluble reactive phosphorus）浓度提升0.32 μM。每个夏季设置三次采样：施肥开始前的6月一次，7月与8月各一次。
