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

Climate Change Impact on the Evolution of the Saline Lakes of the Soan-Sakaser Valley (Central Salt Range; Pakistan): Evidences from Hydrochemistry and Water (δD, δ18O) and Chlorine (δ37Cl) Stable Isotopes

Water, 2019
The surfaces of saline lakes are shrinking at a threatening rate worldwide. Likewise, the Uchhali complex (formed by three saltwater lakes located in the Salt Range, Pakistan) that serves as a major regional source of water for humans and as a habitat ...

Spatiotemporal variability of hydrogen and oxygen stable isotopes in the Han River Basin and the regional hydrological implication

Frontiers in Earth Science
Characterization of the spatiotemporal variability of stable isotopes (δ18O and δD) in the surface water of the Han River Basin (HRB) is critical for tracing basin-scale hydrological cycle processes, identifying moisture-source dynamics, and optimizing ...

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 ...
