We found that 26.3% of the landscape had been harvested during this time period which outweighed growth at the landscape level, resulting in a net tree aboveground biomass change of − 5.7 Mg/ha/yr, and − 2.3 Mg/ha/yr in total aboveground carbon, summed across all the aboveground biomass pools.
Compound identities and abundances are listed in Additional file 4. Phosphatidylcholine (PC) molecules exhibiting partially desaturated, O-linked diacyl (aa) chains of variable length totaling 34 or 36 carbons (sum of both acyl chains) were by far the most abundant metabolites.
Dissolved inorganic carbon (DIC, sum of dissolved carbon dioxide, bicarbonate, and carbonate) in the medium was measured using previously described protocols [ 34].
It is interesting to note that the percentage of overall carbon wasting (sum of orotate, DHO, CBASP, NAA and lactate) in the carbon balance was similar (ca 5.5%) at the studied dilution rates under very different maximal glucose-acetate co-utilisation capability values.
"World backsliding on curbing carbon emissions," summed up a headline in the Bangor Daily News.
Total carbon density, the sum of above-vegetation, fine roots, and soil organic carbon on an area basis was obtained by multiplying the mass of each component by its corresponding weight-basis concentration in each plot.
Total annual carbon dioxide flux sums for the tower site ranged from 1064 to 1382 g C m−2 yr−1, across different years and different gap-filling methods.
This could be attributed to the high organic matter (organic carbon) and high sum of bases in the surface layer of the grazing land (Tables 5, 8).
This property of the carbonate system is known as buffering and can be quantified using the Revelle factor, R [ Revelle and Suess, 1957]: (2) The Revelle factor R is the ratio of the relative change of seawater pCO2 (or, alternatively, CO2 aq)) to the relative change of dissolved inorganic carbon (DIC, the sum of CO2 aq), HCO and CO ) [ Zeebe and Wolf-Gladrow, 2001; Egleston et al., 2010].
Calculate your "carbon footprint," the sum of carbon emissions from all your carbon-producing activities.
The compounds quantified by the PTR-MS (acetaldehyde, ethanol, methanol and terpenes) were multiplied by their carbon number and summed to determine the total concentration of VOCs in ppm C.
