Research on Polar Motion Prediction Accuracy Based on ETH and GFZ Angular Momentum Forecast Products

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Polar motion (PM), a critical element of Earth Orientation Parameters (EOP), is essential for high‐precision applications such as deep space exploration and satellite navigation. Recent advances in prediction methods utilizing Effective Angular Momentum (EAM) data have become a key pathway for enhancing PM forecast accuracy.

A Global, Taxon‐Stratified, High‐Resolution Sampling‐Effort Dataset From GBIF for Bias‐Aware Ecological Modelling

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.

From Soil Threats to Soil Health: Prevention or Remediation

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
Conceptual diagram representing the approach for assessing and combining soil threats and health. ABSTRACT While soil threats and soil health are two interrelated, sometimes confused, concepts, we demonstrated here that a clear separation between these two concepts associated to a mapping of both soil threats and soil health is necessary.

SWOT and Swath Altimetry: A Breakthrough for Global Ocean Prediction

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Since its launch in December 2022, the SWOT (Surface Water and Ocean Topography) satellite with its KaRIn (Ka‐band interferometer) instrument has provided unprecedented, high‐resolution, two‐dimensional views of global Sea Surface Height (SSH), offering crucial insights into ocean dynamics.

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

Geophysical 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
