Community Awareness and Evidence of Dugong (Dugong dugon) Presence in Anjouan, Comoros

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The dugong (Dugong dugon), listed as Vulnerable globally, is poorly documented in the Western Indian Ocean, including the Comoros. We combined Local Ecological Knowledge (LEK) and Passive Acoustic Monitoring (PAM) to assess occurrence and reported encounters around the island of Anjouan.

Ultra-High-Resolution Mapping of Posidonia oceanica (L.) Delile Meadows through Acoustic, Optical Data and Object-based Image Classification

Journal of Marine Science and Engineering, 2020
In this study, we present a framework for seagrass habitat mapping in shallow (5–50 m) and very shallow water (0–5 m) by combining acoustic, optical data and Object-based Image classification.

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Bionic Tactile Skins for Robotics: Fundamentals, Advances, and Future Prospects

SmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Robotic bionic tactile skins (RBTSs), as crucial components of next‐generation robotic systems, have attracted significant attention in recent years. By enabling robots to achieve human‐like tactile perception and interact effectively with their surroundings, RBTSs play an essential role in enhancing robotic intelligence.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

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 ...
