Sestonic particulate carbon, nitrogen, and phosphorus data from the Oskrukuyik Creek, near Toolik Field Station, Alaska, summers 1994-Present

Samples from designated stations from the Oksrukuyik Creek were collected during each summer from 1994 to current time. Phosphorus addition has occurred from 1991 to 1996; station sites are relative distance from the original 1991 dripper. Phosphoric acid was added to the stream to increase soluble reactive phosphorus by 0.32 uM. From 1993 to 1996, Ammonium Sulfate was added along with the Phosphoric Acid. This addition of Ammonium Sulfate was added to the stream to increase N by 7.1 uM. From 1997 to present, the historic fertilized reach has been in recovery. Samples were collected to be analyzed for sestonic particulate carbon, nitrogen, and phosphorus. Note that no data is available for the following years: 2002, 2004, 2006, 2007.

本数据集的样本采集工作于1994年至今的每年夏季开展，采集对象为奥克斯鲁伊克溪（Oksrukuyik Creek）指定监测站点的水体样品。1991年至1996年期间，该溪段实施了磷素添加实验：各监测站点的位置以1991年初始滴施装置为参照，以相对距离进行标注；实验期间向溪流中投加磷酸，将可溶性反应磷（soluble reactive phosphorus）浓度提升0.32 μM。1993年至1996年期间，同步投加硫酸铵（Ammonium Sulfate），以将水体总氮浓度提升7.1 μM。1997年至今，此前施加肥料的河段已进入自然恢复阶段。本次采集的样本用于分析悬浮颗粒态碳、氮及磷的含量。需注意，该数据集缺失2002年、2004年、2006年及2007年的相关数据。
