Geo-χ-Former: A Geodynamically Informed Transformer for Short-Term Polar Motion Prediction in the Excitation Domain

This paper introduces Geo-χ-Former, a geodynamically informed Transformer framework that improves 30-day short-term polar motion prediction by forecasting in the excitation domain using effective angular momentum covariates and calendar encodings, thereby reducing root-mean-square errors by 9.21% and 11.93% compared to standard IERS Bulletin A predictions.

Spatial Assessment of Environmental Risks and Community Perceptions of CarbonGeosequestration for Blue Ecosystem Sustainability in the Niger Delta Nigeria

This study reveals a significant spatial conflict between prospective carbon geosequestration zones and ecologically sensitive blue ecosystems in Nigeria's Niger Delta, compounded by high public risk perception and low awareness, thereby necessitating an integrated, participatory governance framework to ensure sustainable deployment.

Seismic velocity changes associated with a flash flood crisis as a proxy for slope instability

This study demonstrates that ambient noise seismic interferometry can effectively monitor slope instability by detecting a rapid, spatially expanding drop in seismic velocity following the September 2022 flash flood in central Italy, which correlates with pore-pressure propagation and offers a promising proxy for forecasting hydro-geological hazards.

Sensitivity of Cross-equatorial Propagation of Cold Surge to Sea Surface Temperature in the South China Sea

This study demonstrates through numerical experiments that cooler sea surface temperatures in the South China Sea actively strengthen cross-equatorial northerly surges and associated rainfall patterns, confirming that these oceanic conditions are a driving factor rather than merely a response to East Asian cold surges.
