Along‐Strike Seismic Structure of the Andreanof Aleutian Arc Segment and Implications for the Formation of Continental Crust

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.

Dynamics off the Congo River and Its Impact on the Water Exchange Between the Coastal and Open Ocean at Different Timescales

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Congo River represents one of the largest freshwater discharges in the Atlantic Ocean. In this study, we investigate the role of mesoscale and submesoscale dynamics in modulating salinity transport, using a 3 km‐resolution realistic numerical simulation.

Observed Trends and Variability in the Water Masses of the Southern Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract We present SatGEM‐2, a new version of the satellite gravest empirical mode (SatGEM) Atlas for the circumpolar Southern Ocean, incorporating all available CTD and Argo profile data through December 2022. SatGEM‐2 uses in situ hydrographic observations to construct static gravest empirical mode (GEM) fields in pressure–sea surface height (sea ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Controls on Valley‐Floor Width in the Western Andes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce
