Global variability of the composition and temperature at the 410-km discontinuity from receiver function analysis of dense arrays
Margaret Elizabeth Glasgow, Hankui K. Zhang, Brandon Schmandt, Wen-Yi Zhou, Jinchi Zhang
2024, Earth and Planetary Science Letters (643)
Seismic boundaries caused by phase transitions between olivine polymorphs in Earth's mantle provide thermal and compositional markers that inform mantle dynamics. Seismic studies of the mantle transition zone often use either global averaging with sparse arrays or regional sampling from a single dense array. The intermediate approach of this study...
A semi-mechanistic model for partitioning evapotranspiration reveals transpiration dominates the water flux in drylands
E.G. Reich, K. Samuels-Crow, John B. Bradford, M. Litvak, Daniel Rodolphe Schlaepfer, K. Ogle
2024, Journal of Geophysical Research: Biogeosciences (129)
Popular evapotranspiration (ET) partitioning methods make assumptions that might not be well-suited to dryland ecosystems, such as high sensitivity of plant water-use efficiency (WUE) to vapor pressure deficit (VPD). Our objectives were to (a) create an ET partitioning model that can produce fine-scale estimates of transpiration (T) in drylands, and...

Theodore B. Barnhart, Annie L. Putman, Aaron Joseph Heldmyer, David M. Rey, John C. Hammond, Jessica M. Driscoll, Graham A. Sexstone
2024, Water Resources Research (60)
Estimating snow conditions is often done using numerical snowpack evolution models at spatial resolutions of 500 m and greater; however, snow depth in complex terrain often varies on sub-meter scales. This study investigated how the spatial distribution of simulated snow conditions varied across seven model spatial resolutions from 30 to 1,000 m...

Joseph Novak, Rocio Caballero-Gill, Rebecca Rose, Timothy D. Herbert, Harry J. Dowsett
2024, Nature Geoscience (17) 795-802
Several modelling and observational studies suggest deep water formation in the subpolar North Pacific as a possible alternative mode of thermohaline circulation that occurred in the warm Pliocene, a time when global atmospheric partial pressure of carbon dioxide was like the modern atmosphere (~400 ppm). We...

2024, Earth and Space Science (11)
In a warming climate, an intensifying fire regime and higher likelihood of extreme rain are expected to increase watershed sediment yield in many regions. Understanding regional variability in landscape response to fire and post-fire rainfall is essential for managing water resources and infrastructure. We measured sediment yield...
Integrating depth measurements from gaging stations with image archives for spectrally based remote sensing of river bathymetry
Carl J. Legleiter, Brandon Overstreet, Paul J. Kinzel
2024, Water Resources Research (60)
Remote sensing can be an effective tool for mapping river bathymetry, but the need for direct measurements to calibrate image-derived depth estimates impedes broader application of this approach. One way to circumvent the need for field campaigns dedicated to calibration is to capitalize upon existing data. In...

2024, Chemosphere (363)
The environmental ubiquity of tire and road wear particles (TRWP) underscores the need to understand the occurrence, persistence, and environmental effects of tire-related chemicals in aquatic ecosystems. One such chemical is 6PPD-quinone (6PPD-Q), a transformation product of the tire antioxidant 6PPD. In urban stormwater runoff 6PPD-Q can exceed acute toxicity thresholds for several salmonid species and is being implicated...
