CO2 fluxes and ancillary meteo-climatic variables (CZO@Bayelva)

Observing Earth critical zone processes in the Bayelva basin (CZO@Bayelva).

Data represents the average values and the corresponding standard deviation of Net Ecosystem Exchange (NEE), Ecosystem Respiration (ER) and Gross Primary Productivity (GPP) obtained from two different sites in the tundra of the Bayelva river basin: One site (named CZ) is located in the vicinity of the Climate Change Tower. The other one (named "Airport") is in the vicinity of the Ny Alesund Airport. Each average value is obtained as a mean over a set of around 20 point measures for each plot and each sampling date. Flux data are complemented by measurements of soil temperature, soil volumetric water content, air temperature and relative humidity, and solar irradiance. CO2 fluxes are measured using a flux chamber and a LI-COR IRGA by means of the Dynamic Flux Chamber method.

Statement: Study the dynamics of CO2 exchanges between soil, vegetation and atmosphere in the "critical zone" tundra of the area formerly occupied by the retreating Vestre and Austre Brøggerbreen glaciers at Svalbard, in the Bayelva basin (Svalbard, NO).

Point measurements of CO2 fluxes were performed over two different sites in the Bayelva Basin by using a portable Infrared Gas Analyser (IRGA) equipped with a transparent flux chamber (model LiCOR 850 LI-COR Environmental, USA); Net Ecosystem Exchange (NEE) and Ecosystem Respiration (Reco) were sued to calculate the Gross Primary Productivity is calculated. Meteo-climatic variables, including solar irradiance, and soil temperature and water content were concurrently measured. Green Fractional cover was calculated form RGB pictures.
