Major Melting Event on the Ross Ice Shelf, Antarctica, Connected With Enhanced Atmospheric Turbulence

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Ross Ice Shelf (RIS) in West Antarctica experienced extensive surface melting in January 2016, driven by warm humid air transported from over the Southern Ocean. Few studies have reported increased atmospheric water vapor and turbulent mixing during this event in this region, where the availability of surface measurements is challenging ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

Distributed Lower‐Crustal Flow Beneath the Central Xianshuihe–Xiaojiang Fault System: Reconciling Geodesy and Geology

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates. We show that conventional elastic dislocation models yield slip rates and locking depths that conflict with seismic ...

Degeneracy Sensing Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping with Dual‐Layer Resistant Odometry and Scan‐Context Loop‐Closure Detection Backend in Diverse Environments

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This paper presents a degeneracy‐aware light detection and ranging (LiDAR)‐inertial framework that enhances LiDAR simultaneous localization and mapping performance in challenging environments. The proposed system integrates a dual‐layer robust odometry frontend with a Scan‐Context‐based loop‐closure detection backend.

Estimating the botanical composition of bahiagrass–rhizoma peanut pastures using aerial multispectral imagery and deep learning

open access: yesCrop Science, Volume 66, Issue 2, March/April 2026.
Abstract Estimating the botanical composition in mixed pastures is challenging due to resource‐intensive sampling methods overlooking grassland spatial variability. We aimed to (I) classify bahiagrass (Paspalum notatum Flügge) and rhizoma peanut (Arachis glabrata Benth.) in grass–legume pastures using aerial multispectral imagery and machine learning, (

GeoNav: Enhancing field phenotyping with high‐precision global navigation systems integration in the Field Book mobile application

open access: yesCrop Science, Volume 66, Issue 2, March/April 2026.
Abstract Field data collection is a key activity in plant breeding, underpinning efforts to develop crop varieties with improved yields, disease resistance, and climate adaptability. Accurately associating data with the correct field plots is critical for selection and genetic improvement but can be challenging, especially in large experiments.

Performance Validation of Sea Surface Wind Speed Retrieval Algorithms and Products From the Chinese Tianmu-1 Constellation GNSS-R: First Results on Comparison With Other Wind Speed Products

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Tianmu-1 constellation is mainly based on BeiDou/Global Navigation Satellite System radio occultation (GNSS-RO) and BeiDou/GNSS reflectometry (GNSS-R) remote sensing technology, which can simultaneously achieve integrated stereo detection of GNSS-RO ...

Uncovering Hidden Predators: Thermal Drone Detection of Antarctic Fur Seals in Tussac Grass at South Georgia

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We demonstrate that fixed‐wing drones equipped with dual thermal and RGB sensors can effectively detect Antarctic fur seals, including those concealed in tussac grass at South Georgia. Thermal imagery significantly improved detection rates compared with RGB alone, while a combined workflow provided the most accurate population estimates.

Morphological instability in restored intertidal flats: How anthropogenic structures drive early‐stage evolution

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The study focusses on the morphological evolution of worldwide restored intertidal flats. These intertidal flats initially experience high sedimentation rates after the opening of the connection with open waters. The anthropogenic structures cause high morphological instability and are eroded, leading to a self‐cannibalisation of the system.
