 Rapidly rising atmospheric CO2 concentration and it’s
potential impact on future climatic conditions is an issue of global economic and political significance.
Natural biomass respiration is a major carbon source. Understanding soil flux and it’s relationship with other sources and sinks within the carbon cycle are currently subject to increasing scientific scrutiny. The new ACE system (Automated Soil CO2 Exchange system) is designed for the long-term, unattended monitoring of soil flux. The automated design allows the soil area to be exposed to ambient conditions between analysis cycles. The soil chamber then automatically closes prior to soil flux measurements being made. The ACE system features a highly accurate CO2 infrared gas analyser housed directly inside the soil chamber assembly. There is therefore no long gas tubing connections between the chamber and a separate analyser. This close proximity of the analyser ensures the fastest possible response times to CO2 changes and also avoids any potential gas “hang ups” in the long lengths of tubing. Experimental set up is much simpler and the system is much more field robust. See the ACE system in action! (10 seconds, 2 MB)
