2009/8/24
To measure spatial variation in soil CO2 efflux in a secondary beech forest in northern Japan, we took measurements five times over two years at 49 sampling points in a 35 m×35 m grid using a closed c...
A field-based method for simultaneous measurements of the δ18O and δ13C of soil CO2 efflux
field-based method simultaneous measurements δ18O δ13C soil CO2 efflux

Three approaches for determining the stable isotopic composition (δ13C and δ18O) of soil CO efflux were compared. A new technique employed mini-towers, constructed of open-topped piping, that were pla...
