Landscape Changes in the Kitchener Avalanche Path, Aoraki/Mount Cook National Park After the Record‐Breaking July 2022 Storm

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Three‐dimensional landscape changes were investigated in the Kitchener Avalanche Path, Aoraki/Mount Cook National Park, New Zealand, after an extreme storm in July 2022. The Path features an earthen diversion berm constructed in 2018 to mitigate the risk of avalanches to the adjacent Aoraki/Mount Cook Village.

Using Agricultural Production to Evaluate the Novel Method of Reducing the Uncertainty in GNSS-R Soil Moisture Retrieval

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Soil moisture (SM) is one of the important driving factors for promoting photosynthesis of vegetation to produce organic carbon. Global satellite navigation system reflectometry (GNSS-R) has considerable potential in monitoring regional SM due to its ...

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

Oikos, Volume 2026, Issue 3, March 2026.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

Journal of Field Robotics, Volume 43, Issue 2, Page 561-577, March 2026.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Retrieving Ocean Surface Wind Speeds in Real Time on Spaceborne GNSS-R Receivers: Algorithm and Validation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Based on delay-Doppler maps (DDMs) in raw counts generated by spaceborne global navigation satellite system reflectometry (GNSS-R) receivers, retrieving ocean surface wind speeds is feasible, so several spaceborne GNSS-R missions have been carried out ...

Long‐Range Time‐Correlated Single‐Photon Counting Lidar 3D‐Reconstruction From a Moving Ground Vehicle

Journal of Field Robotics, Volume 43, Issue 2, Page 1178-1192, March 2026.
ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

An Estimate of Effective Resolution for CYGNSS Surface Water Detection Revealed by Comparison With Multisensor Optical Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The location of water on the Earth’s surface is critical for a wide range of science and application uses. Global navigation satellite system reflectometry (GNSS-R) is a remote sensing technique with demonstrated potential for identifying areas of
