Biogeochemistry data set for NSF Arctic Photochemistry project on the North Slope of Alaska.

Data file describing the biogeochemistry of samples collected at various sites near Toolik Lake on the North Slope of Alaska. Sample site descriptors include a unique assigned number (sortchem), site, date, time, depth, and category (level of thermokarst disturbance). Physical measures collected in the field include temperature, electrical conductivity, and pH. Chemical analyses include alkalinity; dissolved organic carbon (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); anions (Cl, SO4); and silica. A synthesis of much of the data presented here is published in Cory et al. 2013, PNAS 110:3429-3434; Cory et al. 2014, Science 345:925-928; and Page et al. 2013, Environment, Science, & Technology 47:12860-12867.

本数据集文件记录了采集自阿拉斯加北坡图利克湖（Toolik Lake）周边多个采样位点的生物地球化学相关数据。采样位点的元数据包含唯一分配编号（sortchem）、采样位点、采样日期、采样时间、采样深度以及热喀斯特扰动（thermokarst disturbance）等级。野外实测的物理指标包括温度、电导率与pH值。化学分析指标涵盖碱度、溶解性有机碳（dissolved organic carbon，简称DOC）、无机与总溶解态营养盐（NH4、PO4、NO3、TDN、TDP）、颗粒态碳、氮与磷（PC、PN、PP）、阳离子（Ca、Mg、Na、K）、阴离子（Cl、SO4）以及二氧化硅。本数据集收录的多数数据综合研究成果已发表于以下文献：Cory等人2013年发表于《美国国家科学院院刊》（PNAS）第110卷，页码范围3429-3434；Cory等人2014年发表于《科学》（Science）第345卷，页码范围925-928；以及Page等人2013年发表于《环境科学与技术》（Environmental Science & Technology）第47卷，页码范围12860-12867。
