The influence of ocean circulation changes on atmospheric CO2 hinges primarily on the ability to alter the ocean interior's respired nutrient inventory. Here we investigate the Atlantic overturning circulation at the Last Glacial Maximum and its impact on respired carbon storage using radiocarbon and stable carbon isotope data from the Brazil and Iberian Margins. The data demonstrate the existe...

The structure and morpho...

Rangelands are the most important ecosystem for carbon sequestration. Knowledge of plant response to grazing is one of important requirements for rangeland management. Stocking rate is one of main factors in destruction of the vegetation cover in rangeland ecosystems. Livestock grazing has the potential to substantially alter carbon storage in grassland ecosystem. This study examined the effect...

Although much carbon is removed each year from the earth’s atmosphere by forest growth, the CO2 content of the air has been increasing over the past number of centuries. To calculate the rate of carbon storage in forest ecosystems a number of models have been developed. The models developed in Britain generally combine tree production functions with carbon retention curves for various products....

BACKGROUND: Strawberry puree color is unstable during processing and storage due to oxidative reactions. OBJECTIVE: To determine if strawberry puree prepared under nitrogen or carbon dioxide would result in greater retention of color and anthocyanins than samples prepared under air. METHODS: Purees prepared under carbon dioxide, nitrogen or air were pasteurized and stored at 25◦C. Samples were ...

Interconnected hollow-structured carbon was successfully prepared from a readily available bio-waste precursor (orange peel) by pyrolysis and chemical activation (using KOH), and demonstrated its potential as a high-performing electrode material for energy storage. The surface area and pore size of carbon were controlled by varying the precursor carbon to KOH mass ratio. The specific surface ar...

since renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. given that iran is benefiting from vast steppes, therate of carbon sequestration in them dese...

Caragana microphylla, a native perennial leguminous shrub, is widely used for desertification control in China’s Horqin Sandy Land. We investigated the effects of afforestation using C. microphylla in areas with fixed and active dunes on soil carbon (C) and nitrogen (N) storage in the soil total and light-fraction (LF) organic matter. Compared to the values in the control areas, soil organic ca...

Forests contribute to climate change mitigation by storing carbon in tree biomass. The amount of carbon stored in this carbon pool is estimated by using either allometric equations or biomass expansion factors. Both of the methods provide estimate of the carbon stock based on the biometric parameters of a model tree. This study calls attention to the potential advantages of the data mining tech...

CARBON CAPTURE AND STORAGE (CCS) IS A TECHnology being developed in an attempt to slow global warming. In theory, CCS would prevent carbon dioxide produced from coal-fired power plants from reaching the atmosphere by capturing and storing it permanently underground. The scale of this proposal is remarkable, requiring the capture of tens of billions of tons of carbon dioxide from thousands of co...
