Light stable isotope analyses of hydrogen ( 2 H/ 1 H) and oxygen 18 O/ 16 O) water are used in many terrestrial marine aquatic studies. The advantage using ratios is that molecules serve as ubiquitous already present natural tracers. Within recent years, these have been revolutionized by the development new ratio laser spectroscopy (IRIS) systems cheaper, more robust, mobile compared with traditional mass spectrometry (IRMS). Although easier to operate, also need thorough calibration...
Abstract This study investigated CO 2 degassing and related carbon isotope fractionation effects in the Wiesent River that drains a catchment karst terrain of Franconian Alb, Southern Germany. The river was by physico‐chemical stable analyses water dissolved inorganic during all seasons along 65‐km long downstream transects between source mouth. Calculated p values at were 21 400 ± 2400 µatm. rapidly decreased dropped to an average 1240 330 µatm near About 90% this decrease occurred within...
Abstract Understanding the mechanism of water oxidation to dioxygen represents bottleneck towards design efficient energy storage schemes based on splitting. The investigation kinetic isotope effects has long been established for mechanistic studies various such reactions. However, so far natural abundance determination O 2 produced at solid electrode surfaces not applied. Here, we demonstrate that measurements are possible. Moreover, they experimentally simple and sufficiently accurate...
Air moisture of oceanic origin can be subject to long-range transport and could contribute precipitation at distant places. With ongoing climate change the relationship between water vapour sources sinks is under constant evolution plays an important role for budget assessments. This study analysed monthly integrated event-based samples from two field sites in Western Pamir Mountains (Tajikistan) stable isotope compositions oxygen (δ18O) hydrogen (δ2H) water. The aim was investigate and,...
A newly developed isotope ratio laser spectrometer for CO2 analyses has been tested during a tracer experiment at the Ketzin pilot site (northern Germany) storage. For experiment, 500 tons of from natural reservoir was injected in supercritical state into reservoir. The carbon stable value (δ13C) significantly different background values. In order to observe breakthrough continuously, new instruments were connected stainless steel riser tube that installed an observation well. instrument is...
In the tropics, strong seasonality of monsoon precipitation with recurring droughts leads to large uncertainties regarding evaporative water loss in regional balances. To address these uncertainties, this study investigated evaporation/inflow ratio (E/I) Deduru Oya basin Sri Lanka. The investigation approach relies on a revised Craig–Gordon model stable isotopes (δ18OH2O). A high-resolution survey was carried out, where river samples were collected every two weeks near...
Landuse and climate change alter hydrological processes affect drinking water resources. Practical tools for understanding quantifying these becomes increasingly important, example to sustainably manage groundwater reservoirs. Analyses of the isotopes deuterium (δ2H), oxygen (δ18O), tritium (3H) provide useful tools, which can be applied determine ages, assess bank filtration quantities, identify mixings aquifers or long-term climate-induced changes. The objective...
