Effects of permafrost thaw on nitrogen availability and plant-soil interactions in a boreal Alaskan lowland: II - Nitrogen Data 2013

This dataset examines shifts in extractable soil pore water chemistry along a lowland boreal permafrost thaw chronosequence. Data was collected in 2013 at the APEX Beta and forested study plots, located adjacent to the BNZ experimental forest. Measured parameters include: dissolved inorganic N (DIN), dissolved organic N (DON), free amino acids, total dissolved N (TDN), soil temp. at 10 cm, seasonal ice depth, and volumetric soil moisture at 10 cm. Soil pore water samples and environmental variables were collected every three to four weeks from late June to late September, 2013 for a total of five sampling events.

本数据集旨在探究低地寒带多年冻土解冻时间序列样带上可提取土壤孔隙水化学特性的变化。2013年，于毗邻BNZ实验林的APEX Beta样地与森林研究样地采集相关数据。测定参数包括：溶解态无机氮（dissolved inorganic N, DIN）、溶解态有机氮（dissolved organic N, DON）、游离氨基酸、总溶解态氮（total dissolved N, TDN）、10厘米深度土壤温度、季节冰层厚度，以及10厘米深度体积土壤含水量。2013年6月下旬至9月下旬期间，每3至4周采集一次土壤孔隙水样本与环境变量，共计完成5次采样活动。
