Illuminating the Arctic: Unveiling seabird responses to artificial light during polar darkness through citizen science and remote sensing

Remote Sensing in Ecology and Conservation, Volume 11, Issue 3, Page 312-326, June 2025.
Artificial light at night (ALAN) has global impacts on animals, yet its effects in polar regions remain underexplored. In this study, we analyzed a decade of citizen science data on seabird occurrences in Longyearbyen, using remote sensing data to assess the impact of ALAN during the polar night.

GLRT‐based detection of targets composed of distributed scattering centres

IET Radar, Sonar & Navigation
Attributed scattering problems have been found to be helpful in inverse synthetic aperture radar (ISAR) imaging and target recognition problems. In this model, the scattering centres are divided into two categories: localised and distributed.

Going Deeper With Deep Learning: Automatically Tracing Internal Reflection Horizons in Ice Sheets—Methodology and Benchmark Data Set

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Mapping the internal stratigraphy of ice sheets serves a variety of glaciological applications, from the study of past ice flows to current distribution of surface mass balance and melting to contemporary ice dynamics, all of which are crucial for improving future projections of sea level rise.

Terrestrial Water Storage Changes of Qinghai Lake on the Tibetan Plateau From Joint Inversion of GNSS and InSAR Data

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Although geodetic techniques like Gravity Recovery and Climate Experiment have been widely applied to investigate terrestrial water storage (TWS) variations at regional or basin scales on the Tibetan Plateau (TP) caused by global warming, their coarse spatial has limited the study of individual lakes. In this study, we overcome this limitation

Measurement of Englacial Velocity Fields With Interferometric Radio Echo Sounders

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 6, June 2025.
Abstract The surface velocity of ice sheets is now measured at high spatial and temporal resolutions by satellite‐borne platforms. The availability of this data has enabled rapid progress in both monitoring the evolution of ice sheets and understanding their underlying physical processes.

Analysis of the Utilization of Machine Learning to Map Flood Susceptibility

Journal of Flood Risk Management, Volume 18, Issue 2, June 2025.
ABSTRACT This article provides an analysis of the utilization of Machine Learning (ML) models in Flood Susceptibility Mapping (FSM), based on selected publications from the past decade (2013–2023). Recognizing the challenge that some stages of ML modeling inherently rely on experience or trial‐and‐error approaches, this work aims at establishing a ...

Compressive sensing for interferometric inverse synthetic aperture radar applications

IET Radar, Sonar & Navigation, 2016
The applicability of interferometric inverse synthetic aperture radar (InISAR) techniques to images reconstructed via compressive sensing (CS)‐based algorithms is investigated. Specifically, the three‐dimensional (3D) reconstruction algorithm is applied after exploiting CS for data compression and image reconstruction.
