Physical and chemical data for various lakes near Toolik Research Station, Arctic LTER Summer 1999.

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.

本年度数据集记录了图利克研究站（Toolik Research Station）周边多个湖泊的理化观测数据。采样位点的记录参数涵盖采样点信息、观测日期、观测时间与采样水深。野外使用Hydrolab Datasonde原位（in situ）采集的物理参数剖面数据，包含水温、电导率、pH值、以饱和百分比与毫克每升（mg/l）两种单位计量的溶解氧、以伏特与微克每升（µg/l）两种单位计量的SCUFA叶绿素a值，以及光合有效辐射（Photosynthetically Active Radiation，PAR）。
