Physical and chemical data for various lakes near Toolik Research Station, Arctic LTER Summer 1991.

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。采样位点的描述信息包含位点编号、观测日期、观测时间与水深。在野外使用Hydrolab Datasonde原位采集的物理参数垂直剖面数据包括：水温、电导率、pH值、以饱和度百分比与mg/l为单位的溶解氧、以伏特与µg/l为单位的SCUFA叶绿素-a值，以及光合有效辐射（Photosynthetically Active Radiation，简称PAR）。
