Earth's Lower Mantle Predominated by Ferric Iron‐Rich Bridgmanite Inferred From High Pressure Elasticity Measurements

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The absence of sound‐velocity data spanning the entire lower mantle pressures for (Fe, Al)‐bearing bridgmanite impedes direct comparisons with seismic wave observations, leaving the chemistry of the lower mantle unresolved. The present ultra‐high pressure sound‐velocity measurements of in situ synthesized (Fe, Al)‐bearing bridgmanite up to 130

Submesoscale Energy Cycle in a Coupled Ocean‐Atmosphere Simulation of the Gulf Stream

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the Gulf Stream energy cycle, with emphasis on the submesoscale pathway relative to other energy sinks. Using a high‐resolution coupled air–sea simulation (CROCO–WRF), we construct a Lorenz diagram based on temporally and spatially separated submesoscale and background energy budgets.

Dominant Role of Soil Moisture Regulating Vegetation Water Content During Flash Drought Evolution

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Increasing flash drought exposure raises global concerns regarding terrestrial ecosystem responses. We investigate the effect of concurrent and past rootzone soil moisture (SM) and vapor pressure deficit (VPD) on vegetation optical depth (VOD), a satellite‐based proxy of vegetation‐water content, during flash drought evolution.
