ОписаниеAEC-71-9107 THE DAILY OUTPUT OF CARBON DOXIDE FROM FOREST FLOOR LITTER is measured by the apparatus shown in this photo. The six chambers embedded in the forest floor (lower left) contain various combinations of soil litter and organisms. Carbon dioxide, piped from these six "microcosms" to a gas analyser located on the rack, is measured at 50-minute intervals over a 24-hour cycle by Oak Ridge National Laboratory technical staff.
