Mutual Information assessment of the quality of the GRAV-D airborne gravity data and its compatibility with the NGS’ historical surface gravity database

This study demonstrates that Mutual Information serves as an effective diagnostic tool for assessing the internal consistency of GRAV-D airborne gravity data, evaluating its compatibility with historical surface and satellite datasets, and identifying the specific spectral contributions of airborne observations for future geoid modeling.

Validation of a Modified Normalized Mann-Whitney Fractal Dimension Method for characterizing Permo-Tiassic Khuff Carbonate Reservoirs, Saudi Arabia

This study validates that the modified normalized Mann–Whitney method provides an accurate and reliable approximation of pore-radius-derived fractal dimensions for characterizing Permo-Triassic Khuff carbonate reservoirs in Saudi Arabia, demonstrating near-perfect agreement with the established normalized pore-radius method.

Remote Sensing-Based Baseline Assessment of Reef Extent, Thermal Stress, and Anthropogenic Pressure in the Newly Designated Great Reef Protectorate, Red Sea, Egypt

This preprint establishes the first satellite-derived baseline for Egypt's newly designated Great Reef Protectorate by integrating Sentinel-2 mapping, a 41-year thermal stress reconstruction, and anthropogenic pressure assessments to characterize the reef's extent, record unprecedented 2024 heat stress, and confirm its oligotrophic conditions.

Spatiotemporal Analysis of Climate Variability and Natural Disaster Patterns in Brazil Using Self-Organizing Maps

This study demonstrates that Self-Organizing Maps (SOM) with optimized parameters effectively identify distinct spatiotemporal patterns in Brazil's natural disaster data, revealing that precipitation variability and administrative indicators are key drivers for regional clustering and offering valuable insights for climate risk management and adaptive policy planning.

Modified Normalized Fried Mann Fractal Dimension For Characterizing Pore Structure in Khuff Carbonate Reservoirs, Central Saudi Arabia

This study demonstrates that the Modified Normalized Friedmann Method is a highly reliable alternative to the conventional normalized pore-radius approach for characterizing pore-structure fractal behavior in Khuff carbonate reservoirs, as evidenced by an almost perfect linear correlation between the two methods.

Determinants of climate information use among wheat farmers in Golestan Province, Iran: roles of perception, communication channels, and socioeconomic factors

This study of 383 wheat farmers in Golestan Province, Iran, reveals that belief in climate change, perception of local warming, and access to national advisory hotlines are the primary drivers of climate information use, outweighing socioeconomic factors and highlighting the need for enhanced extension communication and risk awareness strategies.

Three-dimensional deep electrical resistivity structure beneath the Kii Peninsula, southwestern Japan: fluids and their contribution to seismic activities

By mapping the 3-D electrical resistivity structure beneath the Kii Peninsula, this study reveals that impermeable acidic plutons act as barriers to fluid migration from the subducting Philippine Sea slab, thereby controlling the accumulation of slab-derived fluids that trigger deep low-frequency earthquakes and guiding fluid flow that influences microseismicity.

Modelling the potential carbon storage capacity of forests dominated by Pinus sylvestris across European ecological zones

This study develops a site-quality-dependent methodology to estimate the Potential Carbon Storage Capacity of European *Pinus sylvestris* forests, providing a standardized baseline for national greenhouse gas inventories and policy frameworks to evaluate carbon stock losses, gains, and mitigation benefits across diverse ecological zones.
