Standing Meanders of the Antarctic Circumpolar Current: Evidence for Ridge‐Controlled Eddy Saturation

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The standing meanders of the Antarctic Circumpolar Current are key sites of mixing and meridional transport in the Southern Ocean, but their long‐term variability and trends remain poorly understood. Here, we investigate the Pacific‐Antarctic Ridge meander using satellite altimetry data from 1993 to 2023.

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Multispectral Data and LiDAR for Enhanced Georeferencing of Gdanska Glowa's 17th‐Century Fortifications

Archaeometry, Volume 68, Issue 1, Page 94-106, February 2026.
ABSTRACT This study presents a novel remote sensing method to detect 17th‐century environmental elements associated with the historical fortifications of Gdanska Glowa in Poland. By integrating 10‐band multispectral imaging, high‐resolution (1 m) digital elevation models, vegetation metrics and random forest classification within Google Earth Engine ...

Bistatic systems

Archives of Acoustics, 2014
This paper describes key features of a bistatic operation in the hydroacoustic systems, his performance model and constraints imposed by environment and propagation conditions in shallow water.
