Chemistry data for lakes and lakes inlets/outlets samples collected summer 2009, Arctic LTER, Toolik Research Station, Alaska.

Yearly file describing the samples collected at various sites near Toolik Research Station (68 38'N, 149 36'W). Sample site descriptors include an assigned number (sortchem), site, date, time, depth, distance, elevation, treatment, date-time, category, and water type (lake, surface, soil). Physical measures collected in the field include temperature (water, soil, well water), conductivity, pH, average thaw depth, well height, discharge, stage height, and light (lakes). Chemical analysis for the sample include alkalinity; dissolved inorganic and organic carbon (DIC and DOC); inorganic and total dissolved nutrients (NH4, PO4, NO3, TDN, TDP); particulate carbon, nitrogen, and phosphorus (PC, PN, and PP); cations (Ca, Mg, Na, K, and Si); anions (SO4 and Cl); and oxygen. Chlorophyll a was collected at stream sites and for experimental manipulations.

本数据集为年度归档文件，收录了采集自图利克研究站（Toolik Research Station，68°38'N，149°36'W）周边各类采样点位的环境样本。采样点位的元数据信息包含分配编号（sortchem）、点位名称、采集日期、采集时间、采样深度、采样距离、海拔高度、处理方式、日期时间戳、样本类别以及水体类型（湖泊、地表水、土壤水）。野外现场实测的物理指标包括水温、土温、井水温度、电导率、pH值、平均解冻深度、井水位高度、流量、水位标高，以及湖泊的光照强度。样本的化学分析指标涵盖碱度；溶解性无机碳与溶解性有机碳（DIC、DOC）；无机态与总溶解态营养盐（NH4、PO4、NO3、TDN、TDP）；颗粒态碳、氮与磷（PC、PN、PP）；阳离子（Ca、Mg、Na、K、Si）；阴离子（SO4、Cl）；以及溶解氧。研究人员在溪流采样点位及实验操控组中采集了叶绿素a样本。
