Chemical data for six lakes in Wisconsin, USA, 1991-1995.

Chemical data obtained from a Lachat auto-analyzer for six lakes in Wisconsin (Peter, Paul, Tuesday, East Long, Central Long, and West Long Lakes), USA, 1991-1995. There are up to seven samples per sampling date due to Van Dorn collections across a depth interval according to percent irradiance. The autoanalyzer procedures are described in detail in Voichick, N., and J. P. LeBouton. 1994. Methods of the cascading trophic interactions project. Fourth edition. Center for Limnology, Madison, Wisconsin, USA.

本数据集收录了1991年至1995年美国威斯康星州6个湖泊（彼得湖、保罗湖、星期二湖、东长湖、中长湖及西长湖）的化学检测数据，所有数据均由Lachat自动分析仪（Lachat auto-analyzer）测得。本次采样采用范多恩采水器按照辐照度百分率划定深度区间进行分层采集，因此每个采样日期最多可获取7份样品。本数据集所采用的自动分析仪检测方法，详见Voichick N与LeBouton JP于1994年出版的《级联营养相互作用项目方法》（第四版），该文献由美国威斯康星州麦迪逊市湖沼学中心发布。
