Sentences with phrase «isotopic composition also»

Not exact matches

They also used satellite precipitation data to «backsolve» the brine's origins using sodium concentrations, oxygen and hydrogen isotopes, as the isotopic composition of water reflects the condensation temperature and precipitation rate over time.

The authors also monitored the isotopic 13C composition of CO2, which serves as a fingerprint of emissions from coal - fired power plants and matched it to that of the local coal.

The hydrogen isotopic composition of lunar water also varies from region to region, much more dramatically than in Earth.

The measurements show that 4 - Vesta contains the same hydrogen isotopic composition as carbonaceous chondrites, which is also that of Earth.

Sea ice melt (SIM) also has relatively low salinity (S < 5), but its oxygen isotopic composition is similar to that of seawater, from which it is formed (δ18O ≅ 0 to — 6 ‰).

The UniChem connectivity search function allows users to find not only exact matches of their chemical structure across 60 million related molecules from 21 data sources worldwide, but also identifies «equivalent» structures that have the same atom connectivity while differing in stereochemistry or isotopic composition, or which exist in a different salt form.

Instead of CO2 concentrations being about 15 p.p.m.v. lower, the CO2 / temperature shift can also be explained by isotopic composition overestimating temperature by about 1 °C.

I thought one could get other evidence on these matters by looking at the isotopic composition of the CO2 and also by looking at the correlation between CO2 changes and change in O2.
