Landscape Position Project at North Temperate Lakes LTER: Vertical Lake Profiles 1998 - 1999

Parameters characterizing the chemical limnology and spatial attributes of 45 lakes were surveyed as part of the Landscape Position Project. Parameters are measured at or close to the deepest part of the lake. A vertical profile of temperature, dissolved oxygen, and conductivity are collected at 1 meter increments Sampling Frequency: generally monthly for one summer; for some lakes, one or two samples in one summer Number of sites: 45本数据集隶属于景观位置项目（Landscape Position Project）所开展的湖泊调查成果，收录了45个湖泊的化学湖沼学（chemical limnology）与空间属性特征参数。所有参数均在湖泊最深处或临近最深处的区域进行测定。研究人员以1米为间隔，采集温度、溶解氧与电导率的垂直剖面数据。采样频率设置如下：多数湖泊在单个夏季内每月采样1次；部分湖泊仅在单个夏季内采集1至2次样本。本次调查共设置45个采样点位。
