Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract Oceanic lithosphere formed at the global mid‐ocean ridge system makes up >60% of Earth's solid surface. Its uppermost ∼6 km are accreted either magmatically, where mafic melt is available, or tectonically, where this melt is absent. The magmatically accreted lithosphere is known to evolve with age, as demonstrated by its velocity increase ...

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

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