Tropical Cyclone Winds Retrieved From Synthetic Aperture Radar

open access: yes, 2013
This paper describes algorithms used to retrieve high-resolution wind fields in tropical cyclone conditions from synthetic aperture radar (SAR) data acquired at C-band with either co-polarization or cross-polarization.

Characteristics and Trends in Short‐Duration Heavy Rain in Wet‐Season in Hong Kong

open access: yesInternational Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
This study examines the characteristics of heavy rain events (hourly rainfall ≥ 30 mm) in Hong Kong from 2000 to 2024. A statistically significant increasing trend in short‐duration (1–3 h) heavy rain events (3.4 events per decade) in the wet season is observed, primarily due to other mechanisms rather than surface troughs or tropical cyclones. Notably,

Assessing Loggerhead Turtle Exposure to Fisheries in Northwest Africa: Predicted Risk and Management Gaps

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Biologging and Global Fishing Watch data reveal extensive spatial and vertical overlap between loggerhead turtles from the Cabo Verde population and fisheries across the Northeast Atlantic, highlighting areas of high predicted bycatch risk and gaps in current protections. ABSTRACT Bycatch is the accidental capture of non‐target animals in fishing gear,

Multifeature Fusion Neural Network for Oceanic Phenomena Detection in SAR Images

open access: yesSensors, 2019
Oceanic phenomena detection in synthetic aperture radar (SAR) images is important in the fields of fishery, military, and oceanography. The traditional detection methods of oceanic phenomena in SAR images are based on handcrafted features and detection ...

Monitoring dolphinfish catches and diel assemblage fluctuations using eDNA at fish‐aggregating devices

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Fish‐aggregating devices (FADs) are man‐made objects designed to attract fish, with the aim of facilitating spatially heterogeneous aggregations of marine species. These objects influence the structure of pelagic fisheries, consequently affecting fish distributions and interactions. One of the most iconic epipelagic species targeted using FADs

Theoretical Evaluation of Several Possible Along-Track InSAR Modes of TerraSAR-X for Ocean Current Measurements

open access: yes, 2007
The German satellite TerraSAR-X, scheduled for launch in early 2007, will permit high-resolution ocean current measurements by along-track interferometric SAR (along-track InSAR) in various experimental modes of operation, using different subsections of ...

HF Radar Sea-echo from Shallow Water

open access: yesSensors, 2008
HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar ...

Low sediment retention efficiency limits delta formation in tectonically confined high‐energy coastal systems

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Conceptual framework showing how tectonic confinement, steep monsoon‐driven river dynamics, high‐energy coastal processes and offshore sediment dispersal together limit sediment retention at the Narmada–Tapi river mouths, suppressing sustained subaerial delta formation despite high sediment supply. Abstract Although deltaic growth is commonly linked to

US military, airspace, and meteorological radar system impacts from utility class wind turbines: Implications for renewable energy targets and the wind industry

open access: yes, 2013
A substantial number of wind energy projects have been stalled or abandoned in the United States of America (US) due to concerns over the effects of wind turbines on radar installations.

Automatic eddy detection in the MIZ based on YOLO algorithm and SAR images

open access: yesScience of Remote Sensing
The automatic detection and analysis of oceanic eddies within the marginal ice zone using synthetic aperture radar present significant challenges, yet are crucial for both scientific research and practical applications.
