Evaluating and improvement of tree stump volume prediction models in the eastern United States
Forests are considered among the best carbon stocks on the planet. After forest harvest, the residual tree stumps persist on the site for years after harvest continuing to store carbon. A bigger concern is that the component ratio method requires a way to get stump volume to obtain total tree …

Mid-Infrared Studies of Galactic sources: Probing the Relationship Between Polycyclic Aromatic Hydrocarbons and their Physical Environment
… relaxation of polycyclic aromatic hydrocarbons (PAHs) after the absorption of a far-ultraviolet (FUV) photon. PAHs are astronomically significant in that they contain up to 15% of the cosmic carbon inventory and play an important role in the physical and chemical processes of the ISM …

Tracking nuclear generating station emissions and fossil fuel contributions using tree rings in southern Ontario, Canada
… (12C, 13C) and radioactive (14C) isotopes of carbon are an important indicator of the Anthropocene. Carbon from anthropogenic sources can be released to the atmosphere as radiocarbon (14C) from nuclear power and above-ground nuclear weapons testing. Carbon-12 and carbon-13 (12,13C) are derived …

Estimation of net carbon sequestration potential of citrus under different management systems using the life cycle approach
A study was conducted to determine the net carbon sequestration potential of citrus to mitigate climate change. Perennial crops such as citrus have the potential to absorb and sequester carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical …

The Role of the Ocean in MIS 4 Climatic Changes and Atmospheric CO₂ Variability: a Geochemical Fingerprinting Approach
… changes, primarily by releasing geological carbon into the atmosphere and increasing atmospheric CO<sub>2</sub>, with current levels reaching >400ppm, a concentration unprecedented in the last 800ka. This has led to far-reaching socioeconomic consequences for human society and risks for all …

Wetlands Characterization in the Congo River Basin Using Multi-source Remotely Sensed Data and Field Survey
… a network of 548 circular permanent carbon inventory plots of 15 meters radius were established in forested wetlands and dense semi-deciduous forest in order to estimate Above Ground Biomass (AGB) for each forest type and to compare values between forested wetlands and non-wetlands …

Methodological developments for mapping soil constituents using imaging spectroscopy
… and introduce perturbations in the terrestrial carbon reservoirs in vegetation, soil and detritus. Optical remote sensing and in particular Imaging Spectroscopy has shown the potential to quantify land surface parameters over large areas, which is accomplished by taking advantage of the …

Biogeochemistry of Carbon on Disturbed Forest Landscapes
Carbon accreditation of forest development projects is essential for sequestering atmospheric CO2 under the provisions of the Kyoto Protocol. The carbon sequestration potential of surface coal-mined lands is not well known. The purpose of this work was to determine how to measure carbon …

Kolefnisbinding og vöxtur mismunandi skógargerða í þremur skógum á Suðvesturlandi Heiðmörk, Nesjavöllum og Ölfusvatni
Eitt af mikilvægum hlutverkum skógræktar er að binda koldíoxíð (CO2) úr andrúmslofti og geyma sem kolefni (C) í lífmassa og jarðvegi til lengri tíma. Aukin umræða og kröfur um notkun ábyrgra aðferða til þess að meta kolefnisbindingu skóga var aðal kveikjan að þessari rannsókn. Markmið þessa …
