Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...

AGU Advances, Volume 7, Issue 1, February 2026.Abstract The experiences of Earth observation (EO) professionals from underserved and underrepresented backgrounds are under‐documented, which this study seeks to rectify. We interviewed 55 individuals from various organizations supporting underrepresented EO professionals and coded their responses for prevalent themes using standard qualitative ...

Analyzing Geomagnetic Data From the Dusheti Observatory During the Intense Magnetic Storms of 2024
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Geomagnetic storms, intense disturbances in the Earth's magnetosphere, pose risks to both technology and human activity in space. In this study, we analyzed geomagnetic field measurements from the Dusheti Observatory in Georgia during the intense geomagnetic storms of March 3, March 24, and 11 May 2024.

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

Powering AGNs with super-critical black holes
, 2009 We propose a novel mechanism for powering the central engines of Active Galactic Nuclei through super-critical (type II) black hole collapse. In this picture, ~$10^3 M_\odot$ of material collapsing at relativistic speeds can trigger a gravitational shock,

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Hyper‐velocity impacts on planetary surfaces lead to impact craters whose morphology evolves due to exogenous factors such as atmospheric processes, as well as endogenous factors including tectonic and metamorphism. On Earth, erosion processes driven by climate (fluvial, aeolian, glacial processes) progressively erase these structures, or even

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract A small‐volume 6,000 m3 rockslide struck the Lorgino hamlet of Crevoladossola (NW Italy) just before 23:00 UTC on 26 January 2023, at the boundary of a nearby marble quarry. The rockslide severely damaged the mining infrastructure and halted operations for months, fortunately without causing injuries or casualties.
