The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Role of North Pacific Sea Surface Temperatures in Linking Summer Beaufort Sea Ice to Preceding‐Winter ENSO

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Interannual variability of the Beaufort Sea (BFS) ice notably affects the oceanic circulation, pelagic and sympagic ecosystems, and navigation activities. However, key physical pathways regulating interseasonal connections between the El Niño‐Southern Oscillation (ENSO) and BFS ice concentration anomalies in early‐summer (May–July) remain ...

US‐Japan Alliance: Emmeshing Bilateralism Into Broader Multilateralism

open access: yesAsia &the Pacific Policy Studies, Volume 13, Issue 2, May 2026.
ABSTRACT In the 21st Century, geopolitical confrontation between the Eurasian continental powers and the sea powers works to divide Asia. The US‐Japan alliance has transformed itself from Japanʼs asymmetrical security dependence of the Cold War period into a mutual and more integrated partnership today.

Complete Chloroplast Genomes of Ranunculus arvensis and Ranunculus laetus: Comparative Analysis and Phylogenetic Insights

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Here, we de novo assembled the chloroplast genomes of Ranunculus arvensis and Ranunculus laetus, providing comprehensive comparative analysis with 21 congeners. The genomes exhibited conserved quadripartite structures with no major rearrangements, though lineage‐specific variations in atpH position were detected in two species.
