Carbon 14 dating in wine
Humans and animals breathe it out, it comes out of the earth when organic material decays, and it is also created by burning fossil fuels like coal, petrol and natural gas.
CO formed in this way contributes to the strengthening of the greenhouse effect, and thus to a warmer climate.
Fossil fuels are millions of years old so all of the 14C that they once contained has disappeared in the meantime.
CO deriving from fossil fuels can thus be identified easily by the absence of 14C.
In order to investigate the greenhouse gas effect in Europe, one has to measure the concentrations of CO2 from fossil fuels at different places all over the continent.
This could be done with 14C tests of air samples, but the same types of measurements can also be carried out on plants that have absorbed CO2.
Researchers have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide.
1952: An analysis of the carbon-14 radioisotope in a piece of charred oak from an excavated pit at Stonehenge estimates that the mysterious structure on England's Salisbury Plain is 3,800 years old, plus or minus 275 years.
Thus, as the radioactive carbon-14 in dead matter decays to the more plentiful isotope carbon-12, the proportion of C-14 to C-12 declines.
from fossil fuels at different places all over the continent.
This could be done with 14C tests of air samples, but the same types of measurements can also be carried out on plants that have absorbed CO in the atmosphere can come from various sources.
Regional map Wine is the ideal agricultural product for conducting this type of research.
Better quality bottles of wine state on the label the year that the grapes were harvested and the region they come from.
The carbon atoms in the alcohol molecule can be directly traced back to the carbon atom in CO from fossil fuels was in the atmosphere when the grapes were ripening.
