Nutrient and chemical data for various lakes near Toolik Research Station, Arctic LTER, Summer 2003.

Note this file was updated and combined into Decadal file http://dx.doi.org/10.6073/pasta/c964a186ed5a58270602ea44f8c3927b Yearly file describing the physical/chemical values recorded at various lakes near Toolik Research Station. Sample site descriptors include site, date, time, depth. Depth profiles of physical measures collected in situwith Hydrolab Datasonde in the field include temperature, conductivity, pH, dissolved oxygen in both percent saturation and mg/l, SCUFA chlorophyll-a values in both volts and µg/l, and PAR.

请注意，本文件已完成更新并整合至十年期数据集文件（Decadal file），链接为：http://dx.doi.org/10.6073/pasta/c964a186ed5a58270602ea44f8c3927b。
本年度数据集记录了图利克研究站（Toolik Research Station）周边多个湖泊的物理与化学观测值。
采样点位的描述信息包含点位标识、观测日期、观测时间与采样深度。
野外使用Hydrolab Datasonde原位（in situ）采集的物理参数深度剖面数据包括：水温、电导率、pH值、以百分比饱和度与mg/l为单位的溶解氧、以伏特和µg/l为单位的SCUFA叶绿素-a浓度，以及光合有效辐射（PAR，Photosynthetically Active Radiation）。
