GLEON Buoy

LSPA’s water quality buoy collects and transmits data on weather and in-lake conditions. This buoy is part of a global buoy network (Global Lake Ecological Observatory Network).  Instruments record wind speed and direction, humidity, sunlight, water temperature at various levels, and dissolved oxygen in the water.

The instruments on the buoy measure dissolved oxygen approximately 1 meter from the surface and temperature every 2-3 meters down through the water column (17 sensors). It also has what is known as a PAR sensor, which measures sunlight between particular wavelengths, the ones that organisms use. The weather instruments will help to tie in weather specifics when analyzing the other data.
