Aggregate, Volume 7, Issue 9, September 2026.Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning
Journal of Field Robotics, Volume 43, Issue 6, Page 3617-3632, September 2026.ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Multi-beam side-scan sonar [PDF]
, 2001 Conventional single beam side-scan sonars with beams at about 1o are not well suited for the detection and identification of very small objects TS < -25 dB - e.g. minelike objects.

Sea Bottom Line Tracking in Side-Scan Sonar Images Using WTMM-Based Edge Detection
Journal of Marine Science and EngineeringThe topographic features of the seafloor can be observed clearly via high-resolution side-scan sonar imagery. However, the faithful interpretation of a sonar image depends strongly on the accuracy with which the location of the sea bottom line can be ...

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Side-Scan Sonar Imaging: Automatic Boulder Identification
, 2021 Boulder surveys seek to identify prominent boulders which position may collide with planned cable routes, offshore wind farms, or other subsea activities. Data is collected using suitable sensor technologies such as bathymetry from multibeam echosounders
