Furthermore, the measurement of isotope ratios requires the robotic extraction of samples with isotopicratio analysis, which imposes further complexity on such missions. However, isotopicratio measurements alone are unreliable as biogenic processes can yield a variable isotopic signature and can often be replicated under certain abiotic conditions. Isotopicratio measurements can differentiate between biogenic and non-biogenic origins. The isotopicratio of radium will then decrease as the water from the source river enters a bay or estuary.

These isotopicratio differences have had large implications on models of the nature of the solar nebula and the formation of the present (secondary) atmospheres of the terrestrial planets.

These isotopic ratios can be measured by mass spectrometry and employed to gain insights into paleoclimate conditions. Os isotopicratio exceeds 0.129, significantly greater than that of carbonaceous chondrites, but similar to anhydrous ordinary chondrites.

Isotopic ratios in the water in turn depend on a variety of geographic and climatic factors, including temperature, humidity, and latitude. Their isotopic ratios all range around 0.710-0.712, which is not very much above the seawater value. Because these bedrock isotopic ratios are averaged in soils, plants, and, in turn, the animals from a region, they provide very specific average signatures of local environments. For example, differences in lateral isotopic ratios within an ocean can indicate strong water fronts or gyres.

By comparing the detected isotopic ratios to a measured standard, an accurate determination of the isotopic make up of the sample is obtained.

Subsequent studies have found isotopic ratios of krypton, xenon, nitrogen and some other elements whose forms are also unknown in our solar system.
