Furthermore, the measurement of isotope ratios requires the robotic extraction of samples withisotopicratioanalysis, which imposes further complexity on such missions.
From theCambridge English Corpus
However,isotopicratiomeasurements alone are unreliable as biogenic processes can yield a variable isotopic signature and can often be replicated under certain abiotic conditions.
From theCambridge English Corpus
Isotopicratiomeasurements can differentiate between biogenic and non-biogenic origins.
From theCambridge English Corpus
Theisotopicratioof radium will then decrease as the water from the source river enters a bay or estuary.
From
Wikipedia
The method is based on measurements of isotopic ratios of gases dissolved and (trapped) in ice.
From theCambridge English Corpus
Theseisotopicratiodifferences 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.
From
Wikipedia
These isotopic ratios can be measured by mass spectrometry and employed to gain insights into paleoclimate conditions.
From theCambridge English Corpus
Osisotopicratioexceeds 0.129, significantly greater than that of carbonaceous chondrites, but similar to anhydrous ordinary chondrites.
From
Wikipedia
Isotopic ratios in the water in turn depend on a variety of geographic and climatic factors, including temperature, humidity, and latitude.
From theCambridge English Corpus
Their isotopic ratios all range around 0.710-0.712, which is not very much above the seawater value.
From theCambridge English Corpus
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.
From theCambridge English Corpus
For example, differences in lateral isotopic ratios within an ocean can indicate strong water fronts or gyres.
From
Wikipedia
By comparing the detected isotopic ratios to a measured standard, an accurate determination of the isotopic make up of the sample is obtained.
From
Wikipedia
Oxygen isotopic ratios, which may be measured very precisely, yield a unique and distinct signature for each solar system body.
From
Wikipedia
Subsequent studies have found isotopic ratios of krypton, xenon, nitrogen and some other elements whose forms are also unknown in our solar system.
From
Wikipedia
Many new aspects of nucleosynthesis have been discovered from the isotopic ratios within the stardust grains.
From
Wikipedia
Local variations in uranium/thorium/lead content cause a wide location-specific variation of isotopic ratios for lead from different localities.
From
Wikipedia
Measurement of carbon isotopic ratios can be used for detection of adulteration of honey.
From
Wikipedia
For example the isotopic ratios of comet and of interstellar dust are very similar, indicating a common origin.
From
