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.

1994年至今，研究人员于每年夏季采集奥克斯鲁伊克溪（Oksrukuyik Creek）指定监测站的悬浮颗粒样品。1991年至1996年期间，该溪流开展了磷添加实验，各监测站的站位以其与1991年初始滴注装置的相对距离进行标定。研究人员向溪流中投加磷酸，以将可溶性反应态磷（soluble reactive phosphorus）浓度提升0.32微摩尔。1993年至1996年，研究人员同步投加硫酸铵与磷酸，投加硫酸铵的目的是将水体氮浓度提升7.1微摩尔。1997年至今，此前受施肥干预的河段进入自然恢复阶段。本次采集的样品用于分析悬浮颗粒态碳（sestonic particulate carbon）、氮与磷的含量。请注意，2002年、2004年、2006年及2007年无有效观测数据。
