Soil water samples from the drained thaw lake basin near Barrow, Alaska, used for the Biocomplexity Experiment, 2009

In 2009, soil water samples were collected from the drained thaw lake basin used for the Biocomplexity Experiment, near Barrow, Alaska (AK). The northern section of the basin was experimentally flooded. Samples were collected from 0-5 and 5-15 cm depths using Rhizon soil moisture samplers and analyzed for dissolved iron-Fe, organic carbon-C, ultraviolet-UV absorbance at 280nm, ammonium, nitrate, amino N, and phosphate.

(2012) Biogeosciences 9:1-15.2009年，研究人员于阿拉斯加州巴罗（Barrow）附近用于生物复杂性实验（Biocomplexity Experiment）的排水解冻湖盆中采集土壤水样。该湖盆的北部区域被实验性地进行了注水处理。研究人员采用Rhizon土壤水分采样器（Rhizon soil moisture samplers），分别在0~5 cm和5~15 cm的土层深度采集样品，并对样品中的溶解态铁（Fe）、有机碳（C）、280 nm处紫外（UV）吸光度、铵态氮、硝态氮、氨基态氮以及磷酸盐进行了分析检测。相关研究细节可参见Lipson等人（2012）发表于《生物地球科学（Biogeosciences）》第9卷第1-15页的论文。
