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

Ecology 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.

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.

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Enhancing Low‐Latitude Ionospheric Irregularity Prediction With Generalized Linear Models

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The ionosphere poses challenges for accurate forecasting due to its complexity and variability. Irregularities in the lower ionosphere are influenced by local time, season, geographic location, solar activity and space weather, complicating precise predictions.

Beyond Geostrophic and Gradient Wind: Enhancing the Estimation of Climatic Wind Fields From Radio Occultation

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Wind approximations, such as geostrophic and gradient wind, are limited in their ability to accurately represent atmospheric conditions in the presence of significant planetary wave activity. Those approximations, while widely applied in synoptic‐scale wind field estimation, fail to capture the full complexity of atmospheric dynamics under ...

Strong Polar Ionospheric Electron Density Depletion Under Prolonged Northward IMF Bz Condition

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Previous studies have primarily focused on high‐latitude ionospheric‐thermospheric (I‐T) variabilities under southward interplanetary magnetic field (IMF) conditions, while rare studies have investigated the I‐T responses to due northward Bz (NBz), especially in the presence of strong IMF By conditions.
