Semi-Lagrangian transport of oxygen isotopes in polythermal ice sheets: implementation and first results
Semi-Lagrangian transport oxygen isotopes polythermal ice sheets implementation first results
2014/12/19
Modelling the evolution of the Earth system on long timescales requires the knowledge and understanding of driving mechanisms, such as the hydrological cycle. This is dominant in all components of the...
Stable water isotopes in the coupled atmosphere–land surface model ECHAM5-JSBACH
Stable water isotopes coupled atmosphere–land surface model ECHAM5-JSBACH
2014/12/12
In this study we present first results of a new model development, ECHAM5-JSBACH-wiso, where we have incorporated the stable water isotopes H218O and HDO as tracers in the hydrological cycle of the co...
δ18O water isotope in the iLOVECLIM model (version 1.0) – Part 3: A palaeo-perspective based on present-day data–model comparison for oxygen stable isotopes in carbonates
δ18O water isotope LOVECLIM model A paleo-perspective present-day data–model comparison oxygen stable isotopes carbonates
2014/12/12
Oxygen stable isotopes (δ18O) are among the most useful tools in palaeoclimatology/palaeoceanography. Simulation of oxygen stable isotopes allows testing how the past variability of these isotopes in ...
Compound--Specific Hydrogen Isotopes of Lipid Biomarkers in Lake El’gygytgyn, Ne Russia
Arctic Deuterium Organic Geochemistry Paleoclimate Stable Isotopes
2014/10/22
Recent successful drilling operations at Lake El'gygytgyn, NE Russia have recovered sediment cores back to 3.6Ma, representing the longest time-continuous sediment record of past climate change in the...
Interpretation of benthic foraminiferal stable isotopes in subtidal estuarine environments
Interpretation benthic foraminiferal stable isotopes subtidal estuarine environments
2010/1/21
Here we present a novel approach for the interpretation of stable isotope signatures recorded in benthic foraminifera from subtidal estuarine environments. The stable isotopic composition (δ18O and δ1...
Stable isotopes as ecological tracers:an efficient method for assessing the contribution of multiple sources to mixtures
Stable isotopes ecological tracer contribution multiple sources mixtures
2010/1/18
Stable isotopes are increasingly being used as tracers of ecological processes potentially providing relevant information to environmental management issues. An application of the methodology consists...
