n.
One of two or more atoms having the same atomic number but different mass numbers.

[iso- + Greek topos, place (so called because the isotopes of a chemical element occupy the same position in the periodic table of elements).]

i′so·top′i·cal·ly adv.

isotope

(ˈaɪsəˌtəʊp)

i•so•tope

(ˈaɪ səˌtoʊp)

n.
one of two or more forms of a chemical element having the same number of protons, or the same atomic number, but having different numbers of neutrons, or different atomic weights.

i·so·tope

(ī′sə-tōp′)
One of two or more atoms that have the same number of protons but a different number of neutrons. Carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 13 has six protons and seven neutrons.

With an understanding that it is only vegetation that releases these heavier water isotopes into the atmosphere (through transpiration), while normal evaporation doesn't, the researchers were able to compare isotope readings in the earlier nuclear monitoring programme data with isotope recordings in rainfall made during 2000 and 2003 in the Amazon and Andes.
As editor Dave Lentz observes in his introductory chapter "Geochemistry of sediments and sedimentary rock: historical to research perspectives" the developments in mass spectrometer and microanalytical technology have seen an explosion of compositional data over the last decade at levels of precision and detection hitherto unattainable, and this has allowed more stringent constraints to be placed on sedimentary processes, particularly via the use of isotope geochemistry.
