The ratio of carbon to carbon the two stable isotopes of carbon in the modern water of Lake Taupo and the Waikato River tells us that volcanic carbon dioxide is getting into the groundwater from an underlying magma body. Glass wool is acceptable as packing material instead of cotton wool. Additionally, it may have sparked a pillar of fire in the sky visible as far as Egypt. This implies that measurements of carbon isotopes in annual rings can track changes in the carbon source used by trees growing near a volcano, providing a potential method of forecasting future large eruptions. Just like a teenager wanting to be older, volcanoes can lie about their age, or at least about their activities. Any addition of carbon to a sample of a different age will cause the measured date to be inaccurate. We found that the radiocarbon dates and isotope data that underpin the presently accepted "wiggle match" age reached a plateau that is, stopped evolving normally.

Radiocarbon dating considerations
It can also affect terrestrial snails that feed in areas where there is a high chalk content, though no measurable effect has been found for land plants in soil with a high carbonate content—it appears that almost all the carbon for these plants is derived from photosynthesis and not from the soil. An international group of researchers has dated a large volcanic eruption in Iceland to within a few months. This effect is known as isotopic fractionation. This is known as radioactive decay. This is probably because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north.
