Detection of Landslide‐Generated Tsunami by Shipborne GNSS Precise Point Positioning

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the R/V Sikuliaq, a research ship of the

Forward Modeling of Bending Angles With a Two‐Dimensional Operator for GNSS Airborne Radio Occultations in Atmospheric Rivers

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract The Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) technique is used to retrieve profiles of the atmosphere during reconnaissance missions for atmospheric rivers (ARs) on the west coast of the United States. The measurements of refractive bending angle integrate the effects of variations in refractive index over ...

Along‐Track Marine Geoid Resolution Enhancement With SWOT

Earth and Space Science, Volume 12, Issue 3, March 2025.
Abstract Satellite altimetry has been the major data source for marine geoid determination·and gravity recovery in recent decades. In general, altimetry‐derived geoid and gravity anomaly models are typically released with a 1' × 1' gridding interval. However, their actual spatial resolution is far lower than the nominal ∼2 km level.

Assessment of the Performance of SWOT for Observing the Static Ocean Topography

Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.
Abstract Marine geodetic references, such as the mean sea surface (MSS), are currently limited by the spatial resolution of conventional satellite altimeters. We analyze the new swath‐altimetry data from the Surface Water and Ocean Topography (SWOT) satellite, to determine the performance of SWOT for mapping the static ocean topography, and possible ...

Species‐By‐Species Pattern Analysis of Coastal Dune Vegetation

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 2, February 2025.
Abstract Vegetation is crucial for stabilizing and developing coastal dunes. Different plant species exhibit different spatial distributions which reflect their environmental role and adaptation strategy. This study aims to provide a fine‐scale species‐by‐species analysis of vegetation spatial patterns on coastal dunes within the San Rossore–Migliarino–

Crustal Heterogeneity Onshore Central Spitsbergen: Insights From New Gravity and Vintage Geophysical Data

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Gravity data provide constraints on lateral subsurface density variations and thus provide crucial insights into the geological evolution of the region. Previously, gravity data from the Norwegian Arctic archipelago of Svalbard comprised an onshore regional gravity database with coarse station spacing of 2–20 km, offshore gravity profiles ...

Drone‐towed electromagnetic and magnetic systems for subsurface characterization and archaeological prospecting

Near Surface Geophysics, Volume 22, Issue 6, Page 617-635, December 2024.
Abstract Drone‐based geophysical surveying is an emerging measuring platform. High time‐cost efficiency and flexibility to survey over inaccessible areas make drones attractive or sometimes the only feasible option to carry geophysical measurements. This study presents a new drone‐towed electromagnetic induction and magnetic gradient sensor system used

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

Ibis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...

Seamless Map of Depth to the Moho Interface in the Afro‐Arabian Region Using Gravity Data Derived From EGM2008

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract The Afro‐Arabian region is one of the few places on land, where rifting processes at divergent plate boundaries can be thoroughly investigated. One of the crucial factors in understanding rifting processes involves assessing the crustal thickness.
