Mercury and water level fluctuations in lakes of northern Minnesota - sampling site land cover and inundated area data

These data tables summarize land cover classifications, slope measurements, and inundated area estimates for several lakes in northern Minnesota, as part of a larger project seeking to identify associations between young-of-year Yellow Perch mercury content and water level metrics, temperature, and annual deposition data in a multivariate analysis. One table presents inundated area estimates for a range of water surface elevations in 0.1 meter increments between a range of seasonal minimum and maximum water surface elevation values. The other table summarizes the percent cover and number of hectares of each land cover class within a specified buffered area around each study sampling site, along with a measure of the overall net change and standard deviation of slope within the buffered area.

本数据集包含的两张表格汇总了明尼苏达州北部多个湖泊的土地覆盖分类结果、坡度测量值与淹没面积估算值，该数据集隶属于一项旨在通过多变量分析，探究当年生黄鲈（Yellow Perch）体内汞含量与水位指标、水温及年度沉积数据之间关联的大型研究项目。其中一张表格针对季节性最低与最高水面高程区间内的各水面高程（以0.1米为增量步进），给出了对应的淹没面积估算值。另一张表格则汇总了各研究采样点周边指定缓冲区域内各类土地覆盖类型的占比及对应公顷面积，同时还提供了该缓冲区域内坡度的总体净变化量与标准差统计值。
