Inhomogeneous Dust Biases Photometric Redshifts and Stellar Masses for LSST

The Astrophysical Journal Letters
Spectral energy distribution (SED) modeling is one of the main methods to estimate galaxy properties, such as photometric redshifts, z , and stellar masses, M _* , for extragalactic imaging surveys.

Iron Fertilization of the North Pacific Did Not Drive Long‐Term Pliocene to Quaternary Cooling

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract While several hypotheses exist to explain the development of large‐scale perennial Northern Hemisphere ice sheets in the late Pliocene and early Pleistocene, the prevailing view is that a decline in atmospheric carbon dioxide (CO2) drove this substantial change in late Neogene climate.

Mapping Quartz and Feldspar Areal Abundance and Grain Sizes Using Integrated VTIR Data

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Mineral dust is sourced from arid regions around the globe, and its composition impacts regional and global environments by affecting radiation balance, cloud formation, nutrient deposition, and snowmelt. As such, mineral dust plays a key role in Earth's energy and biogeochemical budgets.

Normalized Continental US Tropical Cyclone Damage Estimates From 1900–2023: An Updated Methodology and Expanded Data Set

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study presents expanded and updated normalized economic damage estimates for continental US landfalling hurricanes and tropical storms from 1900 to 2023. Here we refine our previously developed methodology by incorporating radius of maximum wind‐based area weightings for population and housing unit adjustments through time.

The Importance of Sample‐to‐Sensor Distance in Quantitative Micro(Paleo‐)Magnetic Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Information on the past of Earth's magnetic field can be retrieved from magnetic grains in rock samples. Micromagnetic Tomography (MMT) is a recently developed method that uses magnetic surface scans from a Quantum Diamond Microscope (QDM) combined with the position of magnetic grains in rock samples to calculate the magnetic moments of those ...

Feasibility of Crosshole Seismic Tomography for Monitoring In Situ CO2 Mineral Storage in Basalts: A Rock Physics‐ and Seismic Modeling Study

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract In situ CO2 mineral storage is gaining increasing attention as a carbon capture and storage (CCS) technology to reduce anthropogenic CO2 emissions. So far, in situ CO2 mineral storage projects have been monitored predominantly using fluid‐ and isotope geochemical methods.
