Pleistocene paleoenvironmental evolution at continental middle latitude inferred from carbon and oxygen stable isotope analysis of ostracodes from the Guadix-Baza Basin (Granada, SE Spain) [PDF]
, 2006 A representative paleoenvironmental reconstruction of continental middle latitude from ca. 2my to the upper part of Middle Pleistocene (279±77ky) was obtained from the carbon and oxygen stable isotopes analyzed in ostracode shells (Cyprideis torosa ...

Mapping oxygen stable isotopes of precipitation in Italy
Journal of Hydrology: Regional Studies, 2016 Study region: Italy. Study focus: The oxygen isotope composition from 266 pluviometers was used to study the spatial variability of δ18O and its relationship with Italian orography. The local meteoric water lines (LMWLs) of northern, southern and central
