Anomaly Detection in Paleoclimate Records using Permutation Entropy [PDF]
, 2018 Permutation entropy techniques can be useful in identifying anomalies in paleoclimate data records, including noise, outliers, and post-processing issues. We demonstrate this using weighted and unweighted permutation entropy of water-isotope records in a

Bulletin of the Mineral Research and Exploration, 2020 The Salda Lake basin which is in the southwestern Turkey is an important water body in view of environmental values. We used stable isotopes (δD and δ18O), δ3H and 14C composition of the water samples to understand recharge process effective in the ...

Do fluid inclusions preserve δ18O values of hydrothermal fluids in epithermal systems over geological time? : evidence from paleo- and modern geothermal systems, Milos island, Aegean Sea [PDF]
, 2003 Stable isotope compositions of quartz (δ18Oquartz) and fluid inclusion waters (δ18OFI and δDFI) were analysed from Profitis Ilias, a low-sulphidation epithermal gold mineralisation deposit on Milos island Greece, to establish if δ18OFI preserve a record ...

Constraining Holocene hydrological changes in the Carpathian–Balkan region using speleothem δ18O and pollen-based temperature reconstructions [PDF]
, 2014 Here we present a speleothem isotope record (POM2) from Ascunsă Cave (Romania) that provides new data on past climate changes in the Carpathian–Balkan region from 8.2 ka until the present.

The main controls of the precipitation stable isotopes at Kathmandu, Nepal
Tellus: Series B, Chemical and Physical Meteorology, 2020 Precipitation stable isotopes (2H and 18O) are adequately understood on their climate controls in the Tibetan Plateau, especially the north of Himalayas via about 30 years’ studies. However, knowledge of controls on precipitation stable isotopes in Nepal

Seasonal deuterium excess in a Tien Shan ice core: Influence of moisture transport and recycling in Central Asia [PDF]
, 2003 Stable water isotope (δ18O, δD) data from a high elevation (5100 masl) ice core recovered from the Tien Shan Mountains, Kyrgyzstan, display a seasonal cycle in deuterium excess (d = δD − 8*δ18O) related to changes in the regional hydrologic cycle during ...
