Stable water isotopes of seawater at Ocean City during MOSAiC expedition

, 2023
Seawater samples have been taken from the station Ocean City on the main MOSAiC ice floe on legs 1, 2, and 3. Water samples for measurement of stable water isotopes (δ18O, δD) were collected in 50-mL glass screw-cap narrow-neck vials (VWR international ...

Stable isotopes and hydrogeochemical evolutions of groundwater from a typical seismic fault zone in the Mt. Lushan region, Eastern China

Frontiers in Earth Science, 2023
We analyzed the major chemical components, hydrogen (δD) and oxygen isotopes (δ18O), and tritium activity in groundwater from Jiujiang well number 2 (JJ2) as well as atmospheric precipitation and water from the Maweishui spring and Tianhuajing reservoir ...

Can δD and δ18O stable isotopes be used to detect long-range dispersal among carabid beetles?

, 2017
We studied if hydrogen (δD) and oxygen (δ18O) stable isotope values in three common carabid species in intensively managed agricultural landscapes in southernmost Sweden indicate long-range dispersal.

Underlying Climate Controls in Triple Oxygen (16 O, 17 O, 18 O) and Hydrogen (1 H, 2 H) Isotopes Composition of Rainfall (Central Pyrenees)

Frontiers in Earth Science, 2021
Studies of rainfall isotopic composition in the Iberian Peninsula are scarce, and to date, none of them have provided analyses of the triple oxygen isotopes, preventing from the complete understanding of current atmospheric processes in this region.

Generation of normal and adakite-like calc-alkaline magmas in a non-subductional environment: An Sr-O-H isotopic study of the Apuseni Mountains neogene magmatic province, Romania [PDF]

, 2007
Neogene magmatism in the Apuseni Mountains of Romania was active between 15 and 7 Ma, with an isolated final eruption at 1.6 Ma. Several groups of magmatic rocks can be distinguished in the province on the basis of ages, trace elements and isotopic ...

Stable isotopic composition in snowpack along the traverse from a coastal location to Dome A (East Antarctica): Results from observations and numerical modeling

, 2020
Stable isotopic composition (δ18O and δD) in Antarctic snow/ice cores serves as the proxy of past temperature. However, the accuracy of temperature reconstruction is largely dependent on the relationship between water isotopes and local temperature (δ-T)

O, H and C isotopic systematics of Icelandic groundwater [PDF]

E3S Web of Conferences, 2019
Stable water isotopes of oxygen and hydrogen have been studied in Icelandic natural waters since 1960 for hydrological and geothermal research. All the waters are of meteoric and seawater origin.
