Sediment transport inferred by submarine bedforms [PDF]

, 2001
By means of bathymetric and side scan sonar records, the net circulation of sediments caused by tidal currents and waves in the outer Principal Channel of Bahía Blanca Estuary is inferred. On the northern coast of the studied area there are two harbours,

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 ...
