Grassland species effects on soil CO2 flux track the effects of elevated CO2 and nitrogen
• Understanding and predicting the impacts of elevated atmospheric CO2, elevated nitrogen deposition, and decreases in plant diversity require better understanding of the way in which plant species influence soil CO2 flux. • In experimental grassland plots where atmospheric CO2, nitrogen supply, and species composition and diversity were manipulated, species effects on soil CO2 flux during 19 s...
متن کاملEvolution of the Climate System of Mars: Effects of Obliquity Change
Introduction: Greenhouse effect of CO2 may have been the most important factor for the Martian surface environment throughout the history of Mars. Polar ice caps and surface regolith are considered to be large CO2 reservoirs to exchange CO2 with the atmosphere on the Mars (atmosphere-ice caps-regolith (AIR) system). In this respect, Mars has an essentially different climate system from that of ...
متن کاملCO2 flux history 1982–2001 inferred from atmospheric data using a global inversion of atmospheric transport
Based on about 20 years of NOAA/CMDL’s atmospheric CO2 concentration data and a global atmospheric tracer transport model, we estimate interannual variations and spatial patterns of surface CO2 fluxes in the period 01/1982–12/2000, by using a time-dependent Bayesian inversion technique. To increase the reliability of the estimated temporal features, particular care is exerted towards the select...
متن کاملDeterminants of growing season soil CO2 flux in a Minnesota grassland
Soil CO2 flux was measured across 947 plots at 7 experimental grassland sites at the Cedar Creek Natural History Area in order to determine the relationships between soil CO2 flux and environmental factors, living plant biomass, and soil C and N. Soil CO2 flux increased as the day progressed, and was positively related to aboveground biomass, belowground biomass, and soil % C. However, most of ...
متن کاملMeasuring the CO2 flux at the air/water interface in lakes using flow injection analysis.
The carbon dioxide flux at the air/water interface in lakes was calculated after the determination of H2CO3* (free CO2) and atmospheric CO2 using flow injection analysis (FIA) coupled to a conductometric detector. The method is based on the diffusion of CO2 through a hydrophobic membrane into a flow of deionized water, generating a gradient of conductivity proportional to the concentration of C...
