  skos:definition """The isotopic record found in various non-marine records reveal direct
information about the past climate. d18O (delta oxygen-18), 16O and 18O are
isotopes of oxygen with slight differences in atomic weight. Studies using
other isotopes such as Carbon-13, Carbon-14 and Hydrogen are widely used.
Isoptopic analysis is especially important in dendroclimatologic and speleothem
analyses."""@en ;
