We are implementing new technologies for studying the environment through formation of the Global Lake Ecological Observatory Network (GLEON), a grassroots network of scientists and information technology experts who use data from instrumented buoys around the world to understand the complex coupling of physical and biological processes in lakes.

Sensor data from NTL-LTER study lake, Crystal Lake, WI showing changes in dissolved oxygen, algae (measured in terms of the concentration of chlorophyll) and water temperature from spring turnover when the lake is mixing and conditions are homogeneous in the lake, to mid-summer stratification in June-July when distinct thermal layers in the lake create distinct chemical and biological conditions. Detailed sensor data also illustrate short-term 'micro-stratification' in the upper 5 m of the water column associated with calm, hot summer days. Measurements such as these are being used to improve current understanding of lake heat budgets and patterns of primary production in lakes.
