- Description:
- Assessing the precision of different geochemical methods is crucial for quantifying rare earth elements (REEs) and critical minerals (CMs) in coal-bearing sedimentary strata, with application to broader sedimentary systems. This study analyzed 230 samples via portable X-ray fluorescence (pXRF) and subsequently high-graded them for inductively coupled plasma-mass spectrometry (ICP-MS) analysis. Samples originate from the Uinta Region of Utah and Western Colorado, with lithologies including coal, claystone, siltstone, mudstone, shale, sandstone, and igneous dikes. REE quantification relies heavily on pXRF and ICP-MS datasets, but the precision between these two methods is unconstrained, encouraging the investigation into the controlling variables associated with each analytical technique. With precision as the primary objective, several sample homogeneity and spatial experiments were conducted to compare pXRF and ICP-MS datasets. Results indicate that both datasets exhibit the greatest similarity when analyzing semi-equivalent areas and volumes of samples. Across all lithologies, powdered samples consistently exhibit greater precision between pXRF and ICP-MS datasets than whole rock samples, as seen in improved r2 values. This finding supports a proposed spatial grid approach to pXRF that quantifies the homogeneity of a three-dimensional sample, resulting in data statistically similar to that of ICP-MS. Ultimately, coupled high-resolution analyses using complimentary pXRF and ICP-MS methods (recommended herein) provide the greatest understanding of REE enrichment with the objective of precision. This recommended methodology produces an unbiased pXRF dataset, 63.3%-76.7% statistically similar to that of ICP-MS. This development is crucial for the confident utilization of pXRF analysis for geochemical evaluation, especially considering domestic CM resources.

- Description:
- This dataset includes the GEOS-Chem model output and python scripts required to reproduce work outlined in 'Potential Air Quality Side-Effects of Emitting H2O2 to Enhance Methane Oxidation as a Climate Solution' by Mayhew and Haskins. The study investigates the predicted change to a selection of air pollutants resulting from the addition of elevated point sources of H2O2 to GEOS-Chem to simulate a proposed methane mitigation technology. The efficiency of this technology is also assessed according to a simplified theoretical framework which is tested against the GEOS-Chem output.

- Description:
- Skull thickness distributions were collected from infants under 12 months of age (n=266). Data-driven age groups were established based on the variability of skull thickness with age. By providing anatomical standards and guidelines for each age and sex group, this work aims to improve consistency in infant head trauma modeling studies.

- Description:
- This is a data set for generating current densities used for the validation of two methods. Similarly, it gives the electric fields for the 80-minute validation of the two methods. Furthermore, the partial transfer function method calculated electric fields are also deposited in this dataset. Similarly, the spectrum of each source and impulse response obtained from the FDTD model are also included. Finally, the electric fields were obtained for 8 hours using the PTF method.

- Description:
- This dataset includes seismic waveforms for an event used in the study "Effects of 2.5-D ultra-low and ultra-high velocity zones on flip-reverse-stacking (FRS) of the ScS wavefield". In addition, because ultra-high velocity zone (UHVZ) synthetic computations can be challenging when using ray based methods, we include our full waveform solutions for 1-D and 2.5-D UHVZ models as discussed in our manuscript. These can be used to benchmark other methods.
