Lago Grande, Santarem, Para, Brazil (1.5°S, 55.4°oW, >104 ha)

The tropical lake measurements will be made in Lago Grande de Curuai, a large floodplain lake in the Amazon. The lake area varies between roughly 5x10^4 to 20x10^4 ha and the water depth varies between 3-10 m from the high water period to the low water period. The low winds and large heat fluxes suggest that buoyancy driven turbulence will dominate gas exchange in this lake.
