All three samples, the Vatican decreed, were to be tested using nuclear accelerators to measure carbon 14 ratios.

Measurements of organic matter generally measure only organic compounds or carbon, and so are only an approximation of the level of once-living or decomposed matter.

Read more about Saatchi's work and that of other researchers measuring global forests and carbon in our new feature story: Seeing Forests for the Trees and the Carbon: Mapping the World's Forests in Three Dimensions.

Our parent company, Guardian Media Group, is also doing its bit to build our understanding of our carbon footprint by developing a system to measure carbon from the paper supply chain for the first time.

Ashby married Elizabeth Helen Margaret Farries, whom he met while they were working together on incineration techniques for measuring carbon in tissue.

During 1983 and 1984 as part of the NOAA AGASP program, the first measurements of such distributions in the Arctic atmosphere were obtained with an aethalometer which had the capability of measuring black carbon on a real-time basis.

The project aims at developing methodologies and supporting pilot demonstrations on how to reliably measure carbon stored in standing forests.

EPA scientists are working to improve ways to measure black carbon, learn more about its composition and compare its impacts relative to other airborne particles.

Since all TOC analyzers only actually measure total carbon, TOC analysis always requires some accounting for the inorganic carbon that is always present.
