Rhenium-osmium abundance and isotope data obtained for the Nakatengu Creek Section, Japan. Sample collection August 2021 principally funded by NSF-NERC award. The approximately 2000 m stratigraphically thick Cretaceous section mainly comprises organic bearing siltstone, siliceous mudstone, sandstone and interbedded tuff horizons.

Marine sediment core sediment and pore water fraction barium concentration and isotope data with associated error collected during the International Ocean Discovery Programme (IODP) expedition 391 at Walvis Ridge, offshore Namibia, collected November 2021 - February 2022. Latitude and Longitude of each specific sample is listed in the datafile. Samples were measured on the Thermal Ionising Mass Spectrometer at the University of Oxford and have been drift corrected between 1st January 2023 and 30th September 2024. They are the final, complete record of the data. The data has an external error of 0.03 per mil and is deemed reproducible. Ethan Petrou is responsible for collection and processing of the data and can be contacted. The data was collected to increase the number of barium isotope measurements in the modern oceans and would be useful for any modern oceanography or geochemist interested in redox or paleoproductivity.

Rhenium-osmium abundance and isotope data synopsis obtained for the Nakatengu Creek and Soashibetsu-gawa OAE1a (oceanic anoxic event 1a) Sections, Hokkaido, Japan, and the Sauzeries OAE1a Section, France. Sample collection August 2021 principally funded by NSF-NERC award. For the Nakatengu Creek and Soashibetsu-gawa sections approximately 2000 m stratigraphically thick Cretaceous section mainly comprises organic bearing siltstone, siliceous mudstone, sandstone and interbedded tuff horizons. The Re-Os data is published in Youjuan Li et al. ,Radioisotopic chronology of Ocean Anoxic Event 1a: Framework for analysis of driving mechanisms.Sci. Adv.10,eadn8365(2024).DOI:10.1126/sciadv.adn8365 For the Sauzeries OAE1a section, a 20 m interval comprises interbedded marl-dominated, marl-limestone and fine grained clays. This data is currently not published

This website provides interactive access to geospatial isotope data for Great Britain. The site includes isotope data for strontium, oxygen and sulphur distributions across Great Britain. The user can input isotope measurements from a sample and the website will compare it with British data distributions and provide a downloadable map of areas that match the composition of the unknown. The project is rooted in archaeological studies but has applications in the modern world of food traceability.

Clumped isotope analyses, raw data, replicates and temperatures calculated using the empirical calibration of Wacker et al. (2014), recalculated using the [Brand] isotopic parameters.

This dataset contains geochemical data from springs, streams and monsoonal rainwater samples, collected from the Melamchi Valley catchment, Nepal, between 2022 and 2025. The data includes analysis of major ions, stable water isotopes and Sr, Li, Si and C isotopes to investigate chemical weathering along mountain flow paths. Filtered water samples were collected across the Melamchi Valley catchment, with springs grouped into sub-linear transects. Additional time series samples span 2023 to 2025 at bi/weekly sampling at 5 sites.

This is a geochemical dataset accompanying Emmings, J., Poulton, S., Vane, C., Davies, S., Jenkin, G., Stephenson, M., Leng, M., Lamb, A., Moss-Hayes, V. A Mississippian Black Shale Record of Redox Oscillation. Palaeogeography, Palaeoclimatology, Palaeoecology [submitted July 2019]. This dataset includes RockEval pyrolysis, major and trace element (XRF), Fe speciation, C, N and S isotopes and S species analyses through the Upper Bowland Shale in the Craven Basin (Lancashire, UK). This research was conducted by Joe Emmings, PhD researcher at the University of Leicester and British Geological Survey (BGS) between 2014-2018, and as a post-doctoral research associate (PDRA) at the British Geological Survey (2018-2021). The PhD research was funded by the Natural Environment Research Council (NERC), as part of the Central England Training Alliance (CENTA) [grant no. NE/L002493/1] and received CASE funding from the BGS. PDRA research was funded by the British Geological Survey.

Cave drip water, pool water and PO4 (phosphate) dosing experiments from Cueva Llanio, Cantabria, N. Spain and cave speleothem carbonate from global cave systems. The data set includes stable oxygen and hydrogen isotope data from the cave drip waters, cave water temperatures and the results of phosphate dosing experiments. Phosphate oxygen isotope data is presented from the dosing experiments, direct extractions from the cave water and from a number of speleothem calcite samples from global collaborators. Water samples were collected from Cueva Llanio over 3 field trips 2023-24.
