The lakes included in this time series are small, humic bog lakes in the boreal region near Minocqua, WI. They range in depth from 2 to 21.5 m and encompass a range of water column mixing frequencies (termed regimes). Dimictic lakes mix twice per year, typically in fall and spring, while polymictic lakes can mix more than twice throughout the spring, summer, and fall. Meromictic lakes have no recorded mixing events. pH was measured in 2007, while nutrient data were determined in 2008 (with the exceptions of FB, WS, and HK, measured in 2007); the two measurements were taken concurrently with the bacterial biomass collection from the same water sample. Where two values are present in a single cell, the first represents the epilimnion value and the second represents the hypolimnion value. GPS, Global Positioning System.
