Chemistry data for lakes and lakes, inlets/outlets samples collected summer 1988, 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，记录了采集于图利克研究站（Toolik Research Station，68°38'N，149°36'W）周边多个采样点的样本。采样点相关描述信息包含分配编号（sortchem）、采样点名称、采样日期、采样时刻、采样深度、采样距离、海拔高度、处理方案、日期-时间戳、样本类别以及水体类型（湖泊、地表水、土壤水）。野外现场采集的物理测量指标包括：温度（水温、土温、井水温度）、电导率、pH值、平均解冻深度、井水位、流量、水位高度以及光照（仅针对湖泊样本）。样本的化学分析项目涵盖：碱度；溶解态无机碳（dissolved inorganic carbon, DIC）与溶解态有机碳（dissolved organic carbon, DOC）；无机态及总溶解态营养盐（NH4、PO4、NO3、总溶解氮TDN、总溶解磷TDP）；颗粒态碳、颗粒态氮与颗粒态磷（PC、PN、PP）；阳离子（Ca、Mg、Na、K及Si）；阴离子（SO4与Cl）；以及氧气。溪流采样点及实验调控组均采集了叶绿素a样本。
