Summary
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 [...]
Summary
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.
These data were calculated to identify associations between young-of-year Yellow Perch mercury content and water level metrics, temperature, and annual deposition data for lakes in northern Minnesota. Summaries of land cover and slope characteristics within a buffered area around each study site were compiled to identify whether land cover conditions were driving differences in the relationship between water level and mercury content.
