Sub‐annual spatiotemporal dynamics of sediment and organic matter storage in beaver ponds

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
Ponds higher up the beaver cascades showed increasing erosion of sediments following heavier rainfall events, whereas those further down showed increasing sediment accretion. Following periods with less intense rainfall all ponds showed net sediment accretion.

Small object detection in side-scan sonar images based on SOCA-YOLO and image restoration

Frontiers in Marine Science
Although side-scan sonar can provide wide and high-resolution views of submarine terrain and objects, it suffers from severe interference due to complex environmental noise, variations in sonar configuration (such as frequency, beam pattern, etc.), and ...
