A dataset of the mid-brunhes period at site MD05-2925, Solomon Sea: Surface-subsurface planktonic foraminifera stable C-O isotope and Mg/Ca ratios

open access: yesData in Brief, 2021
Here we present derived thermal-hydrological variations data during the Marine isotope stages (MISs) 10–12 using surface and subsurface dwelling planktonic foraminiferal geochemical proxies of a sedimentary core of MD05-2925 (9.3oS, 151.5oE, water depth ...

Isotopic Tracing of Perchlorate Sources in the Environment

open access: yesJournal of Chemistry, 2021
Perchlorate (ClO4−) is an emerging persistent pollutant that is ubiquitous in the environment at trace concentrations. Perchlorate ingestion poses a risk to human health because it interferes with thyroidal hormone production.

Building Mexican isoscapes: Oxygen and hydrogen isotope data of meteoric water sampled across Mexico

open access: yesData in Brief, 2021
Oxygen and hydrogen isotope data of meteoric water samples are compiled from several States across Mexico. This dataset includes 287 oxygen and hydrogen (and deuterium excess) isotope data corresponding to meteoric water collected from the surface ...

Investigating stable oxygen and carbon isotopic variability in speleothem records over the last millennium using multiple isotope-enabled climate models [PDF]

open access: yesClimate of the Past, 2022
The incorporation of water isotopologues into the hydrology of general circulation models (GCMs) facilitates the comparison between modeled and measured proxy data in paleoclimate archives.

Linear Responses in Time-dependent Hartree-Fock-Bogoliubov Method with Gogny Interaction [PDF]

open access: yes, 2012
A numerical method to integrate the time-dependent Hartree-Fock Bogoliubov (TDHFB) equations with Gogny interaction is proposed. The feasibility of the TDHFB code is illustrated by the conservation of the energy, particle numbers, and center-of-mass in ...

Isotopic and magnetic proxies are good indicators of millennial-scale variability of the East Asian monsoon

open access: yesCommunications Earth & Environment, 2023
Past East Asian Monsoon variability has been reconstructed using oxygen isotopes of cave speleothems as well as proxy indicators from Chinese loess sequences.

Fragmentation of exotic oxygen isotopes [PDF]

open access: yes, 2003
Abrasion-ablation models and the empirical EPAX parametrization of projectile fragmentation are described. Their cross section predictions are compared to recent data of the fragmentation of secondary beams of neutron-rich, unstable 19,20,21O isotopes at

Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone

open access: yesNature Communications, 2021
To explore the importance of local vs. global sulfur-cycle controls on variations in pyrite sulfur isotopes, the authors couple carbon-nitrogen-sulfur concentrations and stable isotopes of sediments from the Peruvian oxygen minimum zone, identifying a ...

Do oxygen isotope values in collagen reflect the ecology and physiology of neotropical mammals?

open access: yesFrontiers in Ecology and Evolution, 2015
Stable isotope data provide insight into the foraging ecology of animals. Traditionally, carbon and nitrogen isotope values have been used to infer dietary and habitat preferences.
