Itasca Biological Station Lake Monitoring Data, MN (1905 - 2021)

This dataset is a compilation of lake monitoring efforts across time at the Itasca Biological Station and Laboratories. The first records date back to 1905, and coverage is intermittent throughout 1900's and into the 2000's. Measurements were recorded by several instructors and station staff across several lakes in the Itasca, MN region. At each sampling site, weather conditions, water clarity (via Secchi disk), and depth-specific measurements of temperature, dissolved oxygen, and photosynthetically active radiation were recorded.
