Interestingly the wealthiest grave, with a large cruciform brooch, belonged to the individual of native British ancestry (O4), and the individual without grave goods was one of the two genetically «foreign» ones (O2), an observation consistent with isotope analysis at West Heslerton which suggests that new immigrants were frequently poorer26, 27.

It is appropriate as this point to add that if Bolin & Eriksson's conditions in the last paragraph were true, carbonated beer (Bohren, 1987) and soda «pop» as we know it would be an impossibility with their «buffer» factor (see below); rain and fresh water would not show the observed equilibrium pH of 5.7 (Krauskopf, 1979); and experiments would not had shown complete isotopic equilibrium between CO2 and water in just hours, which in turn is the prerequisite for routine stable isotope analysis involving CO2 (Gonfiantini, 1981).

Coupled with paleontological analyses of marine microfossils in deep - sea sediments, these stable - isotope and trace - element microanalyses provide quantitative measures of global climate and ocean behavior over diverse time scales.

Isotope analysis allows us to identify that this CO2 is the result of «old» carbon combining with «new» oxygen which is a clear signature of fossil fuel combustion produced CO2.
