Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.

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.

A Mass Conservation Model to Study the Evolution of Coastal Soft Cliffs Driven by Sea Level Rise Over Multi‐Century Timescales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Soft cliffed coasts are particularly vulnerable to erosion and their retreat depends on environmental, geological and geomechanical factors. In this work, we use a mathematical modeling approach to understand effects of future global sea level rise on these coasts over multiple centuries.

Influence of Biofilms and Extracellular Polymeric Substances on High‐Frequency Acoustic Backscatter

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Acoustic Backscatter Technique has been used to detect underwater targets and characterize seabed and river floor sediment properties. Microbial biofilms, consisting of microorganisms enclosed in Extracellular Polymeric Substances (EPS), have the potential to modify acoustic backscatter by altering the sediment topography, permeability, and ...
