A gas flux chamber assembly is provided that includes a lift-and-rotate mechanism and a chamber. The chamber is moved between first and second positions, wherein the chamber is positioned over a sample in the first position and is positioned outside of an area above the sample in the second position. In operation, the chamber is first lifted off of the collar and is then rotated, about a rotational axis outside of the area above the collar. These acts are reversed to move the chamber from the second position to the first position.

Gas flux system chamber design and positioning method

A gas flux chamber assembly with a soil collar and a chamber is provided. The chamber is moved between first and second positions, wherein the chamber is positioned on the soil collar in the first position and is positioned outside of an area above the soil collar in the second position. In operation, the chamber is first lifted off of the soil collar and is then rotated, about a rotational axis substantially parallel to the soil collar axis, outside of the area above the soil collar. These acts are reversed to move the chamber from the second position to the first position.
